| 1 | Characteristics of Volcanic Rocks in the Shoshonite Province, Eastern China, and Their Metallogenesis显示文摘The shoshonite province in eastern China is characterized by extensive distribution (ca. 80000 km2) of Late Jurassic-Early Cretaceous (165-100 Ma) shoshonite series with subordinate high-K calc-alkali series. It was formed in a dominantly tensile stress field. In comparison with their analogues in island arcs and active continental margins in other countries, the volcanic rocks in the shoshonite province have their specific characteristics in petrology, mineralogy and geochemistry as well as related mineralization association, which are the comprehensive reflection of the special composition and structure of the mantle and crust of the province and the special Mesozoic regional tectonic setting. | Wang Dezi, Ren Qijiang, Qiu Jiansheng, Chen Kerong,Xu Zhaowen and Zeng Jiahu Department of Earth Sciences, Nanjing University, Nanjing, Jiangsu | 1996 | Acta Geologica Sinica(English Edition)1996，70，3： | 10 |
| 2 | OsMKKK70 regulates grain size and leaf angle in rice through the OsMKK4-OsMAPK6-OsWRKY53 signaling pathway显示文摘Grain size and leaf angle are key agronomic traits that determine final yields in rice.However,the underlying molecular mechanisms are not well understood.Here we demonstrate that the Oryza sativa Mitogen Activated Protein Kinase Kinase Kinase OsMKKK70 regulates grain size and leaf angle in rice.Overexpressing OsMKKK70 caused plants to produce longer seeds.The osmkkk62/70 double mutant and the osmkkk55/62/70 triple mutant displayed significantly smaller seeds and a more erect leaf angle compared to the wild type,indicating that OsMKKK70 functions redundantly with its homologs Os MKKK62 and Os MKKK55.Biochemical analysis demonstrated that OsMKKK70 is an active kinase and that OsMKKK70 interacts with Os MKK4 and promotes Os MAPK6 phosphorylation.In addition,the osmkkk62/70 double mutant showed reduced sensitivity to Brassinosteroids(BRs).Finally,overexpressing constitutively active Os MKK4,Os MAPK6,and Os WRKY53 can partially complement the smaller seed size,erect leaf,and BR hyposensitivity of the osmkkk62/70 double mutant.Taken together,these findings suggest that OsMKKK70 might regulate grain size and leaf angle in rice by activating Os MAPK6 and that OsMKKK70,Os MKK4,Os MAPK6,and Os WRKY53 function in a common signaling pathway that controls grain shape and leaf angle. | Zhiqi Liu Enyang Mei Xiaojie Tian Mingliang He Jiaqi Tang Min Xu Jiali Liu Lu Song Xiufeng Li Zhenyu Wang Qingjie Guan Qijiang Xu Qingyun Bu | 2021 | Journal of Integrative Plant Biology2021，63，12： | 6 |
| 3 | Geological and Geochemical Characteristics and Genesis of the Shaxi Porphyry Copper (Gold) Deposits, Anhui Province显示文摘The Shaki porphyry copper(gold) deposits are a trpical example of porphyry copper deposits associ-ated with diorite in eastern China. Quartz diorite, which hosts the deposits, has a Rb-Sr isochron age of 127.9±1.6Ma. Geochemically, the rock is rich in alkalis (especially sodium), light rare earth elements (LREE) and large-ionlithophile elements (LILE), and has a relatively low initial strontium isotopic ratio (ISr=0.7058); thus it is the productof differentiation of crust-mantle mixing source magma. The model of alteration and mineralization zoning is similarto the Hollister (1974) diorite model. The ore fluids have a relatively high salinity and contain significant amounts ofCO2, Ca2+, Na+ and Cl-. The homogenization temperatures of fluid inclusions for the main mineralization stage rangefrom 280 to 420℃, the δ18O values of the ore fluids vary from 3.51 to 5.52‰, the δD values are in the range between-82.4 and -59.8‰, the δ34S values of sulphides vary from -0.3 to 2.49‰, and the δ13C values of CO2 in inclusionsrange between -2.66 and -6.53‰. Isotope data indicate that the hydrothermal ore fluids and ore substances of theShaxi porphyry copper (gold) deposits were mainly derived from magmatic systems. | XU Zhaowen QIU Jiansheng REN Qijiang XU Wenyi NIU Cuiyi FU Bin | 1999 | Acta Geologica Sinica(English Edition)1999，73，1： | 5 |

| 5 | Effects of high voltage discharge on the human bodies of workers显示文摘In this paper,as it is reported,through mechanism analysis,calculation,testing,measuring in the site and the observation ofbiologic effect on workers as well as the peripheral blood test in vitro,there are low energy X-ray and so forth produced due to high volt-age discharge which are harmful physical and chemical factors.Theexistence of these harmful factors affect workers’ health to a certaindegree.The observed biologic indexes are those of peripheral bloodcell effect,lymphocyte,micronuclear,chromosomal aberration,sisterchromatid exchange,blood serum immune globulin,electroen-cephalogram and brain blood current gram. The vitro peripheralblood test indexes are including those of chromosmal aberration,sister chromatid exchange and blood serum immune globulin.Theresults obtained from the said observation and testing express thatthe above mentioned indexes have obvious significance after thecomparison of those between test group and control group treated bystatistics (i.e.P<0.05).Further,the test results also point out that theenvironment of high voltage discharge will creat injury to the workers,therefore a detail research should be taken. | Yang Baochu Chongqing UniversityZao Wenzhen Radiative medical Science Research Institute,Medical Science Academy of ChinaZhang Maohua Hygienic and Antiepidemic Station of Qijiang | 1991 | Electricity1991，，2： | 4 |
| 6 | Principle and application of three-band gradient difference vegetation index显示文摘Vegetation index is a simple, effective and experiential measurement of terrestrial vegetation activity, and plays a very important role in qualitative and quantitative remote sensing. Aiming at shortages of current vegetation indices, and starting from the analysis of vegetation spectral characteristics, we put forward a new vegetation index, the three-band gradient difference vegetation index (TGDVI), and established algorithms to inverse crown cover fraction and leaf area index (LAI) from it. Theoretical analysis and model simulation show that TGDVI has high saturation point and the ability to remove the influence of background to some degree, and the explicit functional relation with crown cover fraction and LAI can be established. Moreover, study shows that TGDVI also has the ability to partly remove the influence of thin cloud. Experiment in the Shunyi District, Beijing, China shows that reasonable result can be reached using the vegetation index to retrieve LAI. We also theoretically analyzed the reason why the normalized difference vegetation index (NDVI) owns the low saturation point, and show that it is determined by the definition of NDVI and the characteristic of vegetation spectra, and is unavoidable to some degree. Meanwhile, through model simulation, we also indicate that the relationship between simple ratio vegetation index (SR) and LAI closes to a piecewise linear one instead of a linear one, which is mainly caused by the influence of background and different change rates of reflectance in red and infrared bands with LAI increasing. | TANG Shihao, ZHU Qijiang, WANG Jindi, ZHOU Yuyu & ZHAO Feng Research Center for Remote Sensing and GIS, Department of Geography, Beijing Normal University, Beijing 100875, China National Satellite Meteorological Center, China Meteorological Administration, Beijing 100081, China | 2005 | Science China Earth Sciences2005，48，2： | 4 |
| 7 | Identification of ancient ceramics by digital shape characterization显示文摘Shapes are important clues for the identification of ancient ceramics.In this study,digital extraction methods of shape characterization were discussed,using samples of flared mouthed porcelain bowls produced in Jingdezhen Hutian Kiln from the Five Dynasties to the Song and Yuan period.By employing the techniques of image enhancement,edge detection and curve fitting of Matlab,the method using digital shape characterization has advanced accuracy and effectiveness of traditional identification which is based on visual and tactual inspections.Together with the increasingly applied compositional data analysis and thermoluminescence dating technique,the method will further improve and upgrade the scientific identification system for ancient ceramics. | WU Juan LIU YingChun XIONG Lu TANG Min ZHANG MaoLin WU JunMing LI QiJiang HUANG MengXuan LI JiaZhi | 2012 | Science China(Technological Sciences)2012，55，9： | 3 |
| 8 | Scientific studies on pottery and pro-porcelain from group of graves in Henglingshan, Guangdong Province显示文摘The findings of the Henglingshan group of graves, Guangdong Province, were appraised as one of the ten major archaeological excavations in 2000. The pottery and proto-porcelain samples excavated from the group of graves in Henglingshan are very important for studying the development history of Guang-dong ceramics. In this paper, the chemical compositions, micro-structure and physical properties of the samples were systematically analyzed. The results were subjected to multivariate statistical analysis. Different compositional patterns were found for specimens from different periods. The reasons for these variations were discussed. In addition, compared with the pottery and proto-porcelain samples from different production sites in other provinces of China, the obvious regional characters and unique law of the development for ancient ceramics of Guangdong were also discussed. | WU Juan WU JunMing LI QiJiang LI JiaZhi LUO HongJie DENG ZeQun | 2009 | Science China(Technological Sciences)2009，52，10： | 2 |

| 12 | Development of TP310HCbN(07Cr25Ni21CbN) austenitic stainless steel tubes显示文摘Improving the unit heat efficiency,reducing coal consumption and the emission of CO2 and meeting the requirements of environmental protection and energy conservation is the goal of the boiler and the power industry.Developments of large capacity and high parameter ultra-supercritical(USC) units are the tendency of the power industry.There is no doubt that the development of USC units is based on the development of materials, especially the materials used for super-heater and reheater in high-temperature USC boiler.Due to the long time exposure to the harsh environment,such as bearing the 600℃steam oxidation,and withstanding the corrosive flue gas and fly ash erosion,the materials require not only good high-temperature strength,but also a good corrosion resistance.In consideration of the requirements cited above,foreign countries had developed TP310HCbN (07Cr25Ni21CbN) austenitic heat-resistant steel.However,the domestic demands for this material still depend on import and the cost is high,so the boiler and the power industry expects eagerly that these steels can be produced by domestic metallurgical industry,especially Baosteel,to replace the imported products.In order to satisfy the requirements of domestic manufacturing super-heater and reheater used in ultra-supercritical power boiler,after developed T23、T91、T92、S30432 high pressure boiler tube,Baosteel began to develop TP310HCbN (07Cr25Ni21CbN)austenitic stainless steel tube in January of 2007.This study describes the composition design, the manufacturing process of product,and the assessment of performance of Baosteel’s TP310HCbN (07Cr25Ni21CbN).The data indicates that properties of Baosteel’s TP310HCbN(07Cr25Ni21CbN) conform to the ASME SA-213 standard and GB5310 standard,so it can substitute the imported products and is suitable for manufacturing power station boiler of great capacity and high steam parameters. | WANG Qijiang~(1)),ZHU Changchun~(1)) and HONG Jie~(1)) 1) Baosteel Iron &Steel Co.,Ltd.,Research Institute,Baoshan Iron & Steel Co.,Ltd.,Shanghai 201900,China 2) Special Steel Business Unit,Baosteel Iron & Steel Co.,Ltd.,Shanghai 200940,China | 2010 | Baosteel Technical Research2010，4，S1： | 1 |

| 15 | GelNB molecular coating as a biophysical barrier to isolate intestinal irritating metabolites and regulate intestinal microbial homeostasis in the treatment of inflammatory bowel disease显示文摘Inflammatory bowel disease(IBD)is a chronic,immune-mediated inflammatory disease characterized by the destruction of the structure and function of the intestinal epithelial barrier.Due to the poor remission effect and severe adverse events associated with current clinical medications,IBD remains an incurable disease.Here,we demonstrated a novel treatment strategy with high safety and effective inflammation remission via tissue-adhesive molecular coating.The molecular coating is composed of o-nitrobenzaldehyde(NB)-modified Gelatin(GelNB),which can strongly bond with-NH_(2)on the intestinal surface of tissue to form a thin biophysical barrier.We found that this molecular coating was able to stay on the surface of the intestine for long periods of time,effectively protecting the damaged intestinal epithelium from irritations of external intestinal metabolites and harmful flora.In addition,our results showed that this coating not only provided a beneficial environment for cell migration and proliferation to promote intestinal repair and regeneration,but also achieved a better outcome of IBD by reducing intestinal inflammation.Moreover,the in vivo experiments showed that the GelNB was better than the classic clinical medication-mesalazine.Therefore,our molecular coating showed potential as a promising strategy for the prevention and treatment of IBD. | Qijiang Mao Haoqi Pan Yiyin Zhang Yi Zhang Qiuwen Zhu Yi Hong Zhengze Huang Yang Li Xu Feng Yifeng Fang WenChao Chen Pengfei Chen Bo Shen Hongwei Ouyang Yuelong Liang | 2023 | Bioactive Materials2023，，1： | 1 |

| 20 | Pore-water distribution and quantification of diffusive benthic fluxes of nutrients in the Huanghai and East China Seas sediments显示文摘The distribution of nitrate, nitrite, ammonia, phosphate and silicate in pore-water and their exchange between sediments and overlying waters (benthic flux) were determined at nine locations on the shelve of Huanghai and East China Seas. On the basis of the redox po- tential of sediments and nutrients distributions in the pore-waters, it is found that the benthic sediments are being in a suboxic to anoxic environment in the Huanghai and East China Seas. The nutrients distribution in the pore-waters is mainly controlled by the sediment environment, and ammonia is the major inorganic nitrogen in the pore-waters. On the basis of benthic fluxes of nutrients calculated us- ing Fick’s first law, there is remarkable efflux of ammonia, dissolved inorganic nitrogen(DIN), phosphate and silicate from the sedi- ments to the overlying waters in the study area, and their benthic fluxes are 299.3￣2 214.8, 404.4￣2 159.5 , 5.5￣18.8 and 541.3￣1 781.6 μmol/(m2·d) respectively, and perhaps they are the major source of dissolved inorganic nitrogen, phosphate and sili- cate for the overlying water. At most stations, the nitrate flux was from the overlying waters to the sediments, which suggests that sub- oxic organic matter decomposition via denitrification is dominated in the most area of Huanghai and East China Seas. High benthic fluxes appearing in the coastal area and relatively low benthic fluxes occurring in the shelf area are found and are consistent with pri- mary productivity zoning in the study area. On the other hand, the ammonia flux displays an exponential decrease with water depth in- crease and an exponential increase with the bottom water temperature. However, others do not display this trend. | NI Jianyu LIU Xiaoya CHEN Qijiang LIN Yian | 2006 | Acta Oceanologica Sinica2006，25，1： | 1 |
