| 1 | 不同草莓品种果实品质的比较研究显示文摘以大棚草莓栽培品种丰香、明宝、雪蜜、红颊、章姬为试材,从果实外观品质和果实营养成分上对5个草莓品种进行了分析研究。结果表明,红颊和章姬草莓果实大,平均单果重分别为21.25和21.97 g,外形美观,富有光泽;在果实经济性状上红颊优于其他4个品种,果实酸甜适口,香味浓,口感好,品质极佳,果实硬度适中,耐贮运性好,是当前大棚草莓栽培中较为理想的优质大果型草莓品种。雪蜜和丰香草莓果实营养成分上无显著差异,但在耐储性上,雪蜜果实硬度较低,不利于远距离运输,而丰香草莓果实硬度达到了4.00 Pa/cm2,耐储性好。在实际栽培过程中应结合实际情况加以选用。明宝草莓果实颜色橙红色,光泽强,香气浓,酸甜适中,平均单果重为19.32 g,可溶性固形物、蛋白质、糖、酸和维生素C含量上在5个品种中处于中间位置,但其果实硬度最低,只有2.53 Pa/cm2,耐储性最差,适宜在当地自产自销。 | 陈卫平 | 2010 | 江西农业学报2010，22，9： | 44 |
| 2 | Moxibustion regulates inflammatory mediators and colonic mucosal barrier in ulcerative colitis rats显示文摘AIM: To observe the efficacy and mechanism of grainsized moxibustion at different acupoints in a rat model of ulcerative colitis(UC). METHODS: Sprague-Dawley rats were randomly divided into control, UC model, grain-sized moxibustion at a single acupoint(CV 12), grain-sized moxibustion at two acupoints(CV 12 and CV 4), grain-sized moxibustion at three acupoints(CV 12, CV 4, and ST 36), and medication groups(n = 8/group). The UC model was established by enema of trinitrobenzene sulfonic acid. Direct moxibustion was used once a day for 7 d. Disease activity index(DAI) was evaluated before and after the treatment. Morphologic changes of intestinal tissue were observed under an optical microscope. The expression of tumor necrosis factor(TNF)-α and p38 mitogen-activated protein kinase(p38MAPK) in colonic tissue was detected using Western blot, and the levels of occludin and zonula occludens-1(ZO-1) m RNAs were detected using reverse transcription PCR. RESULTS: Compared with the control group, the intestinal mucosae were incomplete in the model group, glandular structures were irregular, and submucosae were edematous, hyperemic, and infiltrated with inflammatory cells. The DAI scores and expression ofTNF-α and p38 MAPK were increased significantly in the model group compared to controls(P s < 0.01), while the m RNA levels of occludin and ZO-1 were reduced significantly(P s < 0.01). Compared with the model group, colonic mucosa and the arrangement of glands were complete and regular in the treatment groups. DAI scores and the expression of TNF-α and p38 MAPK were reduced significantly in moxibustion groups compared to controls(P s < 0.01), while the m RNA levels of occludin and ZO-1 were increased significantly(P s < 0.01). The improvements in the above indices in the three acupoints group and the medication group were superior to those in the single and two acupoints groups(all P < 0.05). CONCLUSION: Reduction of TNF-α and p38 MAPK and increased expression of occludin and ZO-1 in colonic tissue represent a potential mechanism for improved intestinal mucosal tissue repair with grain-sized moxibustion. | Tie-Ming Ma Na Xu Xian-De Ma Zeng-Hua Bai Xing Tao Hong-Chi Yan | 2016 | World Journal of Gastroenterology2016，22，8： | 30 |
| 3 | Research on the Performance of Supercritical CO_2 Dry Gas Seal with Different Deep Spiral Groove显示文摘The performance of supercritical CO_2(SCO_2) dry gas seal(DGS) with different deep spiral groove is investigated with the thermal-fluid-solid coupling method. The performance parameters of DGSs with five different kinds of grooves are obtained. The influence of inlet temperature, inlet pressure, velocity and film thickness on performance is analyzed compared with air DGS. The average film pressure, open force and leakage decrease while the average face temperature and flow velocity increase as the spiral groove number increases. The average film pressure, average face temperature, open force and leakage of DGS with radial different deep groove are higher than those of DGS with circumferential different deep groove respectively under the same spiral groove number while the average flow velocity is the opposite. SCO_2 DGS can generate larger average film pressure, open force and leakage with lower average face temperature than air DGS. SCO_2 DGS could maintain better sealing performance despite larger leakage with the variations of inlet temperature, inlet pressure, velocity and film thickness. The variables hold a more remarkable influence on SCO_2 DGS compared with air DGS. | DU Qiuwan ZHANG Di | 2019 | Journal of Thermal Science2019，28，3： | 19 |
| 4 | 不同环节灌溉用水效率及节水潜力分析显示文摘以漳河灌区为例,在对灌区渠系进行等效概化的基础上,采用经验公式法进行不同工况下不同环节灌溉用水效率的分析计算。结果表明总干及干渠环节和分、斗、农渠环节的渠道水利用系数较大,而支干、分干和支渠环节的渠道水利用系数偏小,渠道断面大小、长度及防渗率是导致渠道水利用系数差异的主要原因。计算分析了不同条件下的灌溉用水效率阈值,达到相应阈值时的投资,以及净节水量和节水率,分析了投资与灌溉用水效率阈值及节水率的关系。表明随投资的增加灌溉用水效率及节水率均提高,但其过程符合报酬递减规律,且节水率的报酬递减速度更快。 | 崔远来 谭芳 郑传举 | 2010 | 水科学进展2010，21，6： | 19 |
| 5 | Effects of the accumulation of the rare earth elements on soil macrofauna community显示文摘The accumulation of rare earth elements (REEs) in soil has occurred due to the pollution caused by the exploitation of rare earth resources and the wide rare earth fertilizers in agriculture. The accumulation of REEs has a toxic effect on the soil macrofauna community. 12 study samples were collected near a mine tailings dam with a large amount of REEs by distance gradient sample method. The total concentration of REEs was analyzed and the results were compared with that of the sample from a control site. The effects of the amount of REEs in the soil on the soil macrofauna community were also analyzed. The results showed that the accumulation of REEs in soil was significant in the study area and its concentration was strongly correlated with the distance from the pollution source. One-way ANOVA analysis indicated the significant differences in soil macrofauna communities among the different sites. The ordination obtained through the redundancy analysis demonstrated that the concentration of REEs and the total nitrogen, total potassium and pH, had affected the soil macrofauna community. A small amount of REEs in the soil can promote the diversity of soil macrofauna, but a large amount of REEs can reduce its diversity. The insect groups of Carabidae and Dermaptera were comparatively sensitive to the concentration of REEs in soil, and could be used as an indicator of soil pollution of REEs. However, the Formicidae and Stibaropus formosanus exhibited a high tolerance to REEs in soil. We believe that it is very important for the soil environment protection to strictly control the application of the rare earth fertilizers in agriculture in China. | 李金霞 红梅 殷秀琴 刘继亮 | 2010 | Journal of Rare Earths2010，28，6： | 18 |

| 12 | Evaluation of the SMOS and SMAP soil moisture products under different vegetation types against two sparse in situ networks over arid mountainous watersheds, Northwest China显示文摘Assessment of the suitability of satellite soil moisture products at large scales is urgently needed for numerous climatic and hydrological researches, particularly in arid mountainous watersheds where soil moisture plays a key role in landatmosphere exchanges. This study presents evaluation of the SMOS(L2) and SMAP(L2_P_E and L2_P) products against ground-based observations from the Upstream of the Heihe River Watershed in situ Soil Moisture Network(UHRWSMN) and the Ecological and Hydrological Wireless Sensor Network(EHWSN) over arid high mountainous watersheds, Northwest China.Results show that all the three products are reliable in catching the temporal trend of the in situ observations at both point and watershed scales in the study area. Due to the uncertainty in brightness temperature and the underestimation of effective temperature, the SMOS L2 product and both the SMAP L2 products show 'dry bias' in the high, cold mountainous area. Because of the more accurate brightness temperature observations viewing at a constant angle and more suitable estimations of single scattering albedo and optical depth, both the SMAP L2 products performed significantly better than the SMOS product.Moreover, comparing with station density of in situ network, station representation is much more important in the evaluation of the satellite soil moisture products. Based on our analysis, we propose the following suggestions for improvement of the SMOS and SMAP product suitability in the mountainous areas: further optimization of effective temperature; revision of the retrieval algorithm of the SMOS mission to reduce the topographic impacts; and, careful selection of in situ observation stations for better representation of in situ network in future evaluations. All these improvements would lead to better applicability of the SMOS and SMAP products for soil moisture estimation to the high elevation and topographically complex mountainous areas in arid regions. | Lanhui ZHANG Chansheng HE Mingmin ZHANG Yi ZHU | 2019 | Science China Earth Sciences2019，62，4： | 10 |
| 13 | 不同分辨率SRTM-DEM的数字地形分析比较研究显示文摘以通化地区为试验区,利用Arc/Info软件,将原始的SRTM数据生成等高线,再插值生成不同分辨率的DEM数据,提取了高程差、坡度、坡向、地形阴影数字地形信息,并根据D8算法,对流域信息进行提取。结果表明:不同分辨率的DEM在描述地形的整体变化上存在的差异很小,但高分辨率的DEM可以更好地反映出地形的细微变化;在水文模拟方面,流域网络的数量及沟壑密度与DEM的分辨率成正相关的关系,但由于高分辨率的DEM信息冗余,在水文模拟方面,提取流域网络的时候会出现生成伪沟谷的现象。 | 安辛克 李琳琳 张运刚 | 2010 | 测绘与空间地理信息2010，33，6： | 10 |

| 17 | RAPD-PCR Analysis on Genetic Relationships Between Cultivars of Tree Peony显示文摘Random amplified polymorphic DNA (RAPD) was used to analyze genetic polymophism of 35Tree Peony cultivars with 7 different color groups. Thirty four primers amplified 418 DNA fragments and 337polymorphic bands (80.6%), including specific DNA markers for 18 cultivars that could be used to differentiate cultivars. The UPGMA method was used to analyze the genetic relationship among cultivars. The results showed that 35 Peony cultivars could be divided into 2 cluster groups when using similarity criteria of 1.5, and into 4 cluster groups when using similarity criteria of 1.0. The result confirmed that the flower color has no relation to the genetic clusters and the Tree Peony cultivars originated from the same area has close genetic relationship. Therefore, genetic background has no large effect on the genetic relationship. The sequence based on polymorphic rate from high to low was Blue groups > Yellow groups > Bark red groups > Blake groups >White groups > Green groups > Red groups. | ZHENG Guo-sheng, CHEN Xiang-ming and MENG Li(College of Life Science, Shandong Agricultural University, Taian 271018 , P.R.China Hefei EducationCollege,Hefei 230001 , P.R.

| 18 | Unified solutions for stresses and displacements around circular tunnels using the Unified Strength Theory显示文摘The unified solutions are presented for stresses and displacements around a circular tunnel subjected to a hydrostatic stress field.The rock mass is assumed to be elastic-brittle-plastic and governed by the Unified Strength Theory.The displacements are obtained accounting for three different definitions for elastic strains and different Young's modulus in the plastic zone.The unified solutions obtained in this paper are especially versatile in reflecting the intermediate principal stress effect to different extents for different materials.The conventional solutions,based on the Mohr-Coulomb failure criterion and the Generalized Twin Shear Stress yield criterion,are special cases of the present unified solutions.The new unified solutions can compare with those computed by the latest generalized Hoek-Brown failure criterion.The results obtained demonstrate the importance of the intermediate principal stress influence for the stresses and displacements analysis.The effects of different definitions for elastic strains and different Young's modulus in the plastic zone on the displacements are significant. | ZHANG ChangGuang1,WANG JiangFeng2 & ZHAO JunHai3 1 Department of Geotechnical Engineering,Tongji University,Shanghai 200092,China 2 North China Institute of Water Conservancy and Hydroelectric Power,Zhengzhou 450011,China 3 School of Civil Engineering,Chang’an University,Xi’an 710061,China | 2010 | Science China(Technological Sciences)2010，53，6： | 8 |

| 20 | Cracking conditions of crude oil under different geological environments显示文摘There are mainly 3 kinds of existing states of oil generating from source rocks,that is,dispersive liquid hydrocarbon inside of source rock,dispersive liquid hydrocarbon outside of source rock and concentrated liquid hydrocarbon outside of source rock.Because of the differences in thermal history and medium conditions around,and the interaction of organic and inorganic matter,the liquid hydrocarbon with 3 kinds of existing state has different cracking conditions.The gas generation dynamics experiments of crude oil matching different mediums indicate that the distribution of activation energy of methane changes a lot according to medium difference.The carbonate has a main influence on oil cracking conditions and can largely reduce its activation energy,which reflects the lower cracking temperature of crude oil.The mudstone takes a second place and the sandstone is the smallest.The catalytic cracking function to the oil of the carbonate,of the mudstone and of the sandstone changes weaken in turn.The corresponding Ro values of main gas generation period in different mediums are as follows:1.5%―3.8%with pure crude oil,1.2%―3.2%with dispersive crude oil in carbonate,1.3%~3.4% with dispersive crude oil in mudstone and 1.4%―3.6%with dispersive crude oil in sandstone.The influence of pressure to crude oil cracking is relatively complicated.In the low heating speed condition, pressure restrains the oil cracking and gas generation,but in the high heating speed condition,pressure has an indistinctive influence to the oil cracking and gas generation.Pressure also makes a different effort in different evolvement stage.Taking the middle and lower Cambrian source rocks in the Tarim Basin as an example,primary oil generating quantity is 2232.24×10 8 t,residual oil and oil cracking gas quantity is 806.21×10 8 t and 106.95×10 12 m 3 respectively. | ZHAO WenZhi,WANG ZhaoYun,ZHANG ShuiChang&WANG HongJun Research Institute of Petroleum Exploration&Development,PetroChina,Beijing 100083,China | 2008 | Science China Earth Sciences2008，51，S1： | 8 |
