| 1 | Potential and challenges of tannins as an alternative to in-feed antibiotics for farm animal production显示文摘Naturally occurring plant compounds including tannins, saponins and essential oils are extensively assessed as natural alternatives to in-feed antibiotics.Tannins are a group of polyphenolic compounds that are widely present in plant region and possess various biological activities including antimicrobial,anti-parasitic, anti-viral, antioxidant, anti-inflammatory, immunomodulation, etc.Therefore, tannins are the major research subject in developing natural alternative to in-feed antibiotics.Strong protein affinity is the well-recognized property of plant tannins, which has successfully been applied to ruminant nutrition to decrease protein degradation in the rumen, and thereby improve protein utilization and animal production efficiency.Incorporations of tannin-containing forage in ruminant diets to control animal pasture bloat, intestinal parasite and pathogenic bacteria load are another 3 important applications of tannins in ruminant animals.Tannins have traditionally been regarded as 'anti-nutritional factor' for monogastric animals and poultry, but recent researches have revealed some of them, when applied in appropriate manner, improved intestinal microbial ecosystem, enhanced gut health and hence increased productive performance.The applicability of plant tannins as an alternative to in-feed antibiotics depends on many factors that contribute to the great variability in their observed efficacies. | Qianqian Huang Xiuli Liu Guoqi Zhao Tianming Hu Yuxi Wang | 2018 | Animal Nutrition2018，，2： | 54 |
| 2 | Structural characteristics and petroliferous features of Tarim Basin显示文摘Using the modern tectonic geology theories andmethods such as the plate tectonic analysis, the paleo-struc-ture analysis, the structural-Iithofacies analysis, and the faultrelated fold and petroleum system, and combining with theseismic data, well drilling data and the circumferential fieldgeology, study on the structural characteristics and petro-leum prospect in the Tarim Basin has been carried out. Re-sults show that the Tarim Basin is a large superimpositionand combination basin with continental crustal basement,composed of a Paleozoic craton and Meso-Cenozoic forelandbasins. The characteristics of the basin are: the kernel partof the basin is the marine facies Paleozoic craton, superim-posed 4 continental facies foreland basins. Though the scaleof the paleozoic craton of the Tarim Basin is relatively small,the structure is steady. The petroleum prospect of the Paleo-zoic craton is: multiphase pool-generation and accumulationcontrolled by ancient uplift. The Meso-Cenozoic forelandbasins in the Tarim Basin, which are distributed on the era-tonic circumference and are a long-term subsidence, turnedinto rejuvenated foreland basins after the Meso-Cenozoicperiod. The petroleum prospects are: coal-bed generatinghydrocarbon, abundant natural gas, pool-generation in laterand recent periods, the oil and gas distribution controlled bythe foreland thrust belt. The structural characteristics ofTarim provide it with a superimposition and combinationpetroleum system of multiple resources, multiple reservoirsand multiphase pool-generation. The oil and gas explorationprospect covers two large fields: the Paleozoic craton and theMeso-Cenozoic foreland thrust belt. | JIA Chengzao~1 & WEI Guoqi~2 1.

| 3 | On Palaeozoic Tectonics in the Alxa Region, Inner Mongolia, China显示文摘Two ophiolitic melange belts in the Late Carboniferous formations have been discovered recently in the Alxa region. One is in the Engger Us fault and possesses properties of oceanic crust. The other is in the Badain Jaran fault and shows properties of a back-arc basin. These two faults, together with the Yagan fault, constitute the important boundaries of tectonic units in the Alax region. The four tectonic units delimited by these faults are different in rock assemblages, metamorphism and geochemistry. They reflect the nature of tectonic environments in which they are found. The tectonic units may be traced and correlated to the eastern and western neighbouring areas. The formation and evolution process of the units and their interaction in the Alxa region may be described in terms of the evolution of the Palaeo-Mongolian Ocean and its continental margins. | WU Tairan HE Guoqi ZHANG Chen | 1998 | Acta Geologica Sinica(English Edition)1998，72，3： | 28 |
| 4 | Effects of grazing on carbon and nitrogen in plants and soils in a semiarid desert grassland,China显示文摘Grazing can modulate the feedback between vegetation and soil nutrient dynamics(carbon and nitrogen),altering the cycles of these elements in grassland ecosystems.For clarifying the impact of grazing on the C and N in plants and soils in the desert grassland of Ningxia,China,we examined the plant biomass,SOC(soil organic carbon),total soil N and stable isotope signatures of plants and soils from both the grazed and ungrazed sites.Significantly lower aboveground biomass,root biomass,litter biomass and vegetation coverage were found in the grazed site compared to the ungrazed site,with decreases of 42.0%,16.2%,59.4% and 30.0%,respectively.The effects of grazing on plant carbon,nitrogen,?15N and ?13C values were uniform among species.The levels of plant carbon and nitrogen in grasses were greater than those in the forbs(except for the carbon of Cynanchum komarovii and Euphorbia esula).Root 15 N and 13 C values increased with grazing,while the responses of root carbon and nitrogen to grazing showed no consistent patterns.Root 15 N and 13 C were increased by 79.0% and 22.4% in the grazed site compared to the ungrazed site,respectively.The values of SOC and total N were significantly lower in the grazed than in the ungrazed sites for all sampling depths(0–10 and 10–20 cm),and values of SOC and total N at the surface(0–10 cm) were lower than those in the deeper soils(10–20 cm).Soil ?15N values were not affected by grazing at any sampling depth,whereas soil ?13C values were significantly affected by grazing and increased by 19.3% and 8.6% in the soils at 0–10 and 10–20 cm,respectively.The soil ?13C values(–8.3‰ to –6.7‰) were higher than those for roots(–20.2‰ to –15.6‰) and plant tissues(–27.9‰ to –13.3‰).Our study suggests that grazing could greatly affect soil organic carbon and nitrogen in contrast to ungrazed grassland and that grazing appears to exert a negative effect on soil carbon and nitrogen in desert grassland. | Hui AN GuoQi LI | 2015 | Journal of Arid Land2015，7，3： | 24 |
| 5 | Differential Hydrocarbon Enrichment and its Main Controlling Factors in Depressions of the Bohai Bay Basin Differential Hydrocarbon Enrichment and its Main Controlling Factors in Depressions of the Bohai Bay Basin显示文摘Significant differential hydrocarbon enrichment occurs in depressions in a petroliferous basin.There are multiple depressions in the Bohai Bay Basin, and each depression as a relatively independent unit of hydrocarbon generation, migration and accumulation, contains significantly different hydrocarbon generation conditions and enrichment degree. On the basis of previous documents and a large number of statistical data, this work comparatively analyzed the differential hydrocarbon enrichment and its major controlling factors in depressions of the Bohai Bay Basin. The results show that depressions in the Bohai Bay Basin have various hydrocarbon enrichment degrees, and can be categorized into four types, namely enormously oil-rich, oil-rich, oily and oil-poor depressions. In general, the enormously oil-rich and oil-rich depressions are distributed in the eastern part of the basin along the Tan-Lu and Lan-Liao faults, whereas depressions in the western part of the basin are poor in hydrocarbons. Moreover, the vertical distribution of hydrocarbons is also highly heterogeneous, with Pre-Paleogene strata rich in hydrocarbons in the northern and western depressions, Paleogene strata rich in hydrocarbons in the entire basin, and Neogene strata rich in hydrocarbons in the off-shore areas of the Bohai Bay Basin. From early depressions in onshore areas to the late depressions in offshore areas of the Bohai Bay Basin, the source rocks and source-reservoir-cap rock assemblages gradually become younger and shallower, and the hydrocarbon resource abundance gradually increases. Hydrocarbon supplying condition is the key factor constraining the hydrocarbon enrichment for different depressions,while the main source-reservoir-cap rock assemblage, sufficient hydrocarbons and the transportation capacity of faults control the vertical distribution of hydrocarbons. The main factors controlling hydrocarbon enrichment are different for different layers. The hydrocarbon supplying condition of source rocks is the key controlling factor, whereas the source-reservoir configuration, the main sourcereservoir-cap rock assemblages, and the fault transportation are the main factors of hydrocarbon enrichment in the Paleogene, Paleogene and Neogene, respectively. | JIANG Youlu LIU Hua SONG Guoqi WANG Yongshi LIU Jingdong ZHAO Kai LYU Xueying | 2017 | Acta Geologica Sinica(English Edition)2017，91，5： | 15 |
| 6 | Effects of dietary alfalfa flavonoids extraction on growth performance,organ development and blood biochemical indexes of Yangzhou geese aged from 28 to 70 days显示文摘This experiment was conducted to study the effects of dietary alfalfa flavonoids extraction supplemental level on growth performance, organ development and blood biochemical indexes of Yangzhou geese at the age of 28 to 70 days. Two hundred and forty 21-day-old healthy male geese with similar body weight were randomly distributed into 4 groups with 6 replicates per group and 10 geese per replicate. Geese in the control group were fed a basal diet and the others in the experimental groups(groups 1,2, and 3) were fed experimental diets supplemented with 150, 300 and 450 mg/kg alfalfa flavonoids extraction(the concentration of it was 81%), respectively. The experiment had 7 days for pre-test and 42 days for formal test.The results showed that the final body weight and average daily intake of group 2 were significantly higher than those of other groups(P < 0.05). The average daily gain of group 2 was significantly higher than that in the control group and group 1(P < 0.05). There was no significant difference in feed-to-gain ratio between each group(P > 0.05). Pre-slaughter live weight, carcass weight, slaughter rate, semieviscerated weight, semi-eviscerated rate, eviscerated weight, eviscerated rate, leg muscle weight and leg muscle rate had no significant difference between each group(P > 0.05). The breast muscle weight and ratio of each test group were significantly higher than those in the control group(P < 0.05) and the group2 was the best. The abdominal fat weight and ratio in the group 1 were significantly higher than those in the control group and group 3(P < 0.05) and the tibia weight in the group 2 was significantly higher than that in the control group and group 1(P < 0.05); There were no significant differences in heart weight,liver weight and the gland stomach weight among all groups(P > 0.05). Spleen weight in test groups was significantly higher than that in the control group(P < 0.05). The bursa weight and muscular stomach weight in the group 2 were significantly higher than those in the control group and group 1(P < 0.05). In serum, total cholesterol, triglycerides, low-density lipoprotein and urea nitrogen in the group 2 were significantly lower comparing with those in the control group(P < 0.05). High-density lipoprotein in the group 2 was significantly higher than that in other groups(P < 0.05). There were no significant differences in total serum protein, albumin, globulin and albumin/globulin among all groups(P > 0.05). Alanine aminotransferase and aspartate transaminase(AST) in groups 2 and 3 were higher than those in the group1 and control group but not obvious(P > 0.05) and alkaline phosphatase(ALP) in groups 1 and 2 was higher than that in the control group and group 3(P > 0.05). It is concluded that alfalfa flavonoids extraction added in dietary feed improve the growth performance, organ development and blood biochemical indexes of Yangzhou geese. It is concluded that 300 mg/kg supplemental level of the dietary alfalfa flavonoids extraction is optimal in this experiment. | Yinyin Chen Xiaoxiao Gong Guodong Li Miao Lin Yongjiu Huo Shengli Li Guoqi Zhao | 2016 | Animal Nutrition2016，，4： | 14 |
| 7 | Flake tantalum powder for manufacturing electrolytic capacitors显示文摘The FTP200 flake tantalum powder was introduced.The microstructures of the powder with leaf-like primary particles having an average flakiness of 2 to 20 and porous agglomerated particles were observed.The chemical composition,physical properties,and electrical properties of the FTP200 powder were compared with those of the FTW300 nodular powder.The FTP200 powder is more sinter-resistant,and the surface area of the flake tantalum powder under sintering at high temperature has less loss than that of the nodular tantalum powder.The specific capacitance of the flake tantalum powder is higher than that of the nodular tantalum powder with the same surface area when anodized at high voltage.Thus,the flake tantalum powder is suitable for manufacturing tantalum solid electrolytic capacitors in the range of median and high(20-63 V) voltages. | HE Jilin YANG Guoqi PAN Luntao LIU Hongdong BAO Xifang | 2008 | Rare Metals2008，27，1： | 13 |
| 8 | Relationship between Geological Structures and Hydrocarbon Enrichment of Different Depressions in the Bohai Bay Basin显示文摘The Bohai Bay Basin contains many depressions with varying degrees of hydrocarbon enrichment associated with the geological structures of different depressions. This study discussed the relationship between the geological structures and hydrocarbon enrichment of the depressions in the Bohai Bay Basin. Based on the Paleogene strata distribution and the length to width ratio of different depressions, their geological structures are divided into three types in plan-view: open(length/width < 2), narrow(length/width > 4) and transitional types(length/width 2–4). In cross section, the geological structures can be divided into dustpan I, dustpan II and double-faulted types. Based on tectonic evolution and sedimentary characteristics, the depressions are classified into early-formed, inherited and late-formed categories. Generally, narrow depressions are mainly located in the northeast and southwest of the Bohai Bay Basin, while open depressions are dominantly distributed in the central area of the basin; late-formed depressions are mainly around the Bohai sea area, and early-formed depressions are mostly located in the periphery of the basin. Geological structures of the depressions control the formation of the source, reservoir and cap rocks as well as hydrocarbon accumulation setting, and further influence the pay zones and oil-bearing sequence. In detail, dustpan II and doublefaulted depressions mainly have A-type sags, which often possess better hydrocarbon generation conditions than dustpan I ones; hydrocarbons in open dustpan II depressions tend to accumulate in the central uplift areas or buried hill, while those in narrow dustpan I depressions always accumulate in gentle slope belts. The oil-bearing sequence for different evolutional depressions corresponds well with the sedimentary strata of the main development stages of depressions. In early-formed depressions, hydrocarbons are mainly enriched in deeply buried reservoirs, while in late-formed depressions hydrocarbons are abundant in the relatively shallow traps. In summary, most inherited and late-formed dustpan II depressions are enriched in hydrocarbons due to their extensive source rocks and good source–reservoir–seal assemblages, whereas dustpan I and early-formed depressions are relatively poor in hydrocarbons. | JIANG Youlu LIU Hua SONG Guoqi WANG Yongshi LIU Pei Lü Xueying | 2015 | Acta Geologica Sinica(English Edition)2015，89，6： | 13 |

| 11 | Effects of bamboo vinegar powder on growth performance and mRNA expression levels of interleukin-10,interleukin-22,and interleukin-25 in immune organs of weaned piglets显示文摘The aim of this study was to explore the effects of bamboo vinegar powder on growth performance,diarrhea situation and mRNA expression levels of cytokines i.e., interleukin-10(IL-10), interleukin-22(IL-22), and interleukin-25(IL-25) in immune organs of weaned piglets, and to accumulate theoretical data for the application of bamboo vinegar powder in weaned piglet production. Forty-five crossbred(Duroc × Landrace × Yorkshire, all male) weaned piglets with similar body weight(6.74 ± 0.17 kg) at 31 days of age were randomly assigned to 5 treatments with 3 replicates per treatment and 3 piglets in each replicate. The five treatments were as follows: CON(a basal diet), ANT(the basal diet + 0.12% antibiotics),BV1(the basal diet + 0.1% bamboo vinegar powder), BV5(the basal diet + 0.5% bamboo vinegar powder),BV10(the basal diet + 1.0% bamboo vinegar powder). This experiment lasted 35 days. The growth performance and diarrhea situation were recorded. The relative mRNA expression levels of IL-10, IL-22 and IL-25 in liver, spleen, duodenum and mesenteric lymph nodes were detected by real-time PCR. Feed:gain of BV5 was significantly lower than that of CON(P < 0.05). In comparison with CON, diarrhea rate and diarrhea index of BV1 and BV5 all tended to decrease(P < 0.1). Compared with CON, mRNA expression level of IL-10 in liver of ANT tended to be lower(P < 0.1) and these of BV1, BV5 and BV10 were significantly reduced(P < 0.05). The mRNA expression levels of IL-10 in duodenum of ANT, BV1, BV5 and BV10 were all lower than those of CON, of which BV10 had significantly decreased IL-10 mRNA expression in duodenum(P < 0.05). The mRNA expression levels of IL-22 in duodenum of ANT, BV1, BV5 and BV10 all tended to be inhibited compared with CON(P < 0.1). With the increase of bamboo vinegar powder dosage, mRNA expression levels of IL-25 in spleen and mesenteric lymph nodes of BV1, BV5 and BV10 tended to be up-regulated. Overall, bamboo vinegar powder could improve growth performance,and regulate mRNA expression levels of IL-10, IL-22 and IL-25 in immune organs of weaned piglets. The dosage at 0.5% showed optimum effects. | Yongjiu Huo Zhengxu Liu Han Xuan Chunbin Lu Lihuai Yu Wenbin Bao Guoqi Zhao | 2016 | Animal Nutrition2016，，2： | 11 |
| 12 | Mechanical Properties of Methane Hydrate-Bearing Interlayered Sediments显示文摘The complex distribution of gas hydrate in sediments makes understanding the mechanical properties of hydrate-bearing sediments a challenging task.The mechanical behaviors of hydrate-bearing interlayered sediments are still poorly known.A series of triaxial shearing tests were conducted to investigate the strength parameters and deformation properties of methane hydrate-bearing interlayered sediments at the effective pressure of 1 MPa.The results indicate that the stress-strain curves of hydrate-bearing interlayered sediments are significantly different from that of hydrate-bearing sediments.The peak strength,Young's modulus,initial yielding modulus,and failure mode are deeply affected by the methane hydrate distribution.The failure behaviors and mechanism of strain softening and hardening patterns of the interlayered specimens are more complicated than those of the integrated specimens.This study compares the different mechanical behaviors between integrated and interlayered specimens containing gas hydrate,which can serve as a reference for the prediction and analysis of the deformation behaviors of natural gas hydrate reservoirs. | DONG Lin LI Yanlong LIU Changling LIAO Hualin CHEN Guoqi CHEN Qiang LIU Lele HU Gaowei | 2019 | Journal of Ocean University of China2019，18，6： | 11 |
| 13 | Discovery of mantle and lower crust xenoliths from early Cretaceous volcanic rocks of southwestern Tianshan,Xinjiang显示文摘In Tuoyun area of southwestern Tianshan, mantle and lower crust xenoliths are present In the volcanic rocks with ages of 101-123 Ma. Mantle xenoliths include mineral megacrysts such as kaersutite and pargasite, feldspar, biotite, and rare pyroxene and rock fragments such as perodotite, pyroxenite, amphibolite, and rare glimmerite. Lower crust xenoliths are mainly banded and massive granulite. The volcanic rocks were produced by within-plate magmatism. Occurrence of hydrous and volatile mineral megacrysts, amphibolite, and some pyroxenite containing hydrous and volatile minerals indicates that mantle metasomatism was intense. Undoubtedly, this discovery is very important to understanding of the crust-mantle structure and geodynamic background in depth in southwestern Tianshan and geological correlation with adjacent regions. | Baofu Han Xuechao Wang Guoqi He Tairan Wu Maosong Li Yulin Liu Shiguang Wang | 1999 | Chinese Science Bulletin1999，44，12： | 11 |
| 14 | A Discussion on the Origin of Shale Reservoir Inter-Laminar Fractures in the Shahejie Formation of Paleogene, Dongying Depression显示文摘This paper was conducted on the shale reservoir in the Dongying depression in the Shahejie Formation of Paleogene. Based on detailed core description, rock thin sections, argon ion polishing, scanning electron microscopy(SEM) analysis, CT scanning and carbon-oxygen isotopic test, the formation mechanism of the inter-laminar fractures(or seams) and their development conditions were discussed by comprehensive analysis of the diagenetic evolution features and the reservoir space evolution characteristics. The results show that the laminated composite pattern in Dongying depression was dominated by vertical distribution of laminated calcite and clay minerals. Contrasted to the traditional understanding, development degree of inter-laminar fractures was much lower. Pure fluid between layers cannot exist without framework minerals, and the pre-existing well connected pore or horizontal overpressure micro seam was favorable paths of fluid migration. From the points of inter-laminar fractures origin mechanism and its evolution, the so called seams, were much more complex than traditional understanding that hydrocarbon generation raised the pore pressure and led to the parallel microfractures. But the inter-laminar fractures had little relationship with that whether the lamination was developed or bedding boundary was clear or not. In fact, the shale reservoir inter-laminar fractures were not rigorous fracture. They were controlled by pre-existing inter-granular pore(or seam) or dissolved pore, which distributed along carbonate laminae boundary and were connected by later super pressure, dissolution and the seepage force. And the development conditions were burial depth(bigger than 3 000 m) and the Ro value(>0.6%). Discussion on its origin and evolution has important petroleum geological significance on optimizing reservoir segment and favorable target areas selection. | Huimin Liu Shun Zhang Guoqi Song Shoupeng Zhang Xuefeng Hao Zhonghuai Xie Ningning Xu Peng Liu | 2017 | Journal of Earth Science2017，28，6： | 10 |
| 15 | Geobiological processes of the formation of lacustrine source rock in Paleogene显示文摘Gypsum-salt rocks and coccolith calcareous shale are widely deposited in the lower part of the Paleogene Shahejie Formation in the Dongying Sag,Shandong Province.The gypsum-salt rock is believed to be formed during the earlier deposition in salt lake,while the overlying coccolith shale in saline lake with relatively low salinity.By comparing the lake environment and lacustrine microbial communities between ancient and recent lakes,cyanobacteria are regarded as the main representative of productivity during the formation of gypsum-salt strata series,with the annual productivity of 1500-2000 gC m-2 yr-1.Based on the research of ultramicrofossils in the calcareous shale,coccolith is considered as the main contributor to the productivity during the formation of calcareous shale.On the basis of statistic data of sedimentary rates,shale laminations,and coccolith fossils in each lamination,the quantitative value of productivity is calculated,with the annual productivity of 2250-3810gC m-2 yr-1(averagely 3120 gC m-2 yr-1).Statistic data of large amount of pyrite framboids indicate that the lower water column was persistently in sulfidic or anoxic conditions during the deposition of gypsum-salt strata series,but it changed to be dysoxic when the coccolith calcareous shale was deposited.Both of these water conditions are favorable for the preservation of organic matter.It is estimated that the organic carbon burial efficiency of the Lower Paleogene salt lakes and saline lakes of Dongying Depression is about 10%-15%,which is calculated and analyzed using the multi-parameter geobiological model. | LI GuoShan WANG YongBiao LU ZongSheng LIAO Wei SONG GuoQi WANG XueJun XU XingYou | 2014 | Science China Earth Sciences2014，57，5： | 10 |
| 16 | Silurian to Devonian foreland basin in the south edge of Tarim Basin显示文摘Based on the theory of plate tectonics, combin-ing with the isotopic dating of ophiolite, igneous and volcan-ics, geochemical test, rare earth element analyze and seismicinterpretation, this paper studies the pre-Carboniferous tec-tonics and sedimentary formation of the south edge of theTarim Basin and proves that there exists the Kunlun Oceanunder tensional tectonics during the Sinian and Cambrian inthe south edge of the Tarim Plate. After that, due to the colli-sion orogenesis, there formed the peripheral foreland basinin the south edge of Tarim. The Upper Silurian and Devo-nian molasses sedimentary system superposed on the Sinianand Middle Silurian passive margin flysch sedimentary sys-tem and formed the bivariate structure of the foreland basin.And at the same time, based on the field geology and seismicinterpretation, we have identified that the formation of theSilurian and Devonian have the character of half depositwhich shows thick in the south area and thin in the north,and the pre-Carboniferous thrust compression tectonics re-mained in the foreland thrust belt, which further demon-strates that there existed the Silurian and Devonian periph-eral foreland basin on the south edge of the Tarim Basin. | WEI Guoqi JIA Chengzao LI Benliang CHEN Hanlin | 2002 | Chinese Science Bulletin2002，47，S1： | 10 |
| 17 | Study of Pigment Epithelium-derived Factor in Pathogenesis of Diabetic Retinopathy显示文摘Diabetic retinopathy(DR), a major micro-vascular complication of diabetes, has emerged as a leading cause of visual impairment and blindness among adults worldwide. However,aside from pathological damage, the traditional laser and multi-needle operation treatments required for more advanced disease can cause further damage to the visual field and increase the operation risk. Therefore, the development of new therapeutic strategies for the prevention and treatment of DR is essential..Some emerging evidence now indicates that pigment epithelium-derived factor(PEDF), a multifunctional protein,can target multiple pathways to exert neurotropic,.neuroprotective, anti-angiogenic, anti-vasopermeability, anti-inflammation, anti-thrombogenic, and anti-oxidative effects against DR. This review addresses the functions of PEDF in different pathways that could lead to potential therapeutics for the treatment of DR. | Jing Zang Guoqi Guan | 2015 | Eye Science2015，30，2： | 10 |
| 18 | Meso-Cenozoic Tectonic Events Recorded by Apatite Fission Track in the Northern Longmen-Micang Mountains Region显示文摘There is a cross-cutting relationship between the E-W trending structures and the NE-trending structures in the northern Longmen-Micang Mountains region,which reflects possible regional tectonic transition and migration.Apatite fission track(AFT) analyses of 15 samples collected from this area yield apparent ages varying from 30.3±4.2 Ma to 111.7±9.0 Ma and confined-track-lengths ranging from 10.6±0.3 μm to 12.4±0.1 μm.Four specific groups were identified on the basis of the Track Age Spectrum Calculation(TASC) patterns,i.e.,143-112Ma,93.6-88?Ma,42-40Ma and ~25.6Ma.These age groups correspond to the spatial distributions of datasets and may represent four tectonic events.Together with the regional deformation patterns,the four age groups are interpreted to indicate tectonic superposition,transition and migration during the Meso-Cenozoic with the following possible order:(1) the Micang Mountains belt was dominated by the E-W trending structure during 143-112Ma;(2) the contraction of the Longmen Mountains belt from the NW to the SE during 93.6-88Ma led to the superposition of the NE-trending structures over the E-W trendinding structures;(3) dextral strike-slip shear dominated the Longmen Mountains belt at 42-40Ma;(4) westward migration of the active tectonic belt occurred from 93.6-25.6Ma in a break-back sequence in the northern Longmen Mountains belt.The Late Cenozoic tectonics in the northern Longmen Mountains belt are characterized by the dextral strike-slip shear and the occurrence of westward break-back sequence of deformations.As a result,north-south differences in deformations along the Longmen Mountains belt were intensified since the Miocene time and strains were mainly accumulated in the hinterland of the Longmen Mountains instead of being propagated to the foreland basin. | LEI Yongliang JIA Chengzao LI Benliang WEI Guoqi CHEN Zhuxin SHI Xin | 2012 | Acta Geologica Sinica(English Edition)2012，86，1： | 8 |

| 20 | Low side lobe pattern synthesis using projection method with genetic algorithm for truncated cone conformal phased arrays显示文摘A hybrid method for synthesizing antenna's three dimensional(3D) pattern is proposed to obtain the low sidelobe feature of truncated cone conformal phased arrays. In this method,the elements of truncated cone conformal phased arrays are projected to the tangent plane in one generatrix of the truncated cone. Then two dimensional(2D) Chebyshev amplitude distribution optimization is respectively used in two mutual vertical directions of the tangent plane. According to the location of the elements,the excitation current amplitude distribution of each element on the conformal structure is derived reversely, then the excitation current amplitude is further optimized by using the genetic algorithm(GA). A truncated cone problem with 8×8 elements on it, and a3 D pattern desired side lobe level(SLL) up to 35 dB, is studied. By using the hybrid method, the optimal goal is accomplished with acceptable CPU time, which indicates that this hybrid method for the low sidelobe synthesis is feasible. | Guoqi Zeng Siyin Li Yan Zhang Shanwei L | 2014 | Journal of Systems Engineering and Electronics2014，25，4： | 7 |
