2Possible early Neoproterozoic magmatism associated with slab window in the Pingshui segment of the Jiangshan-Shaoxing suture zone: Evidence from zircon LA-ICP-MS U-Pb geochronology and geochemistry显示文摘We report here geochemical data, U-Pb zircon ages, and Hf isotopes for the high-Mg diorites (HMDs), Nb-enriched basaltic porphyrys (NEBPs) and plagiogranites (PLAGs) in the Pingshui segment of the Jiangshan-Shaoxing suture zone. The HMDs are characterized by high Mg# (>60), high Na and LREE contents, depletion of HREE and HFSE, and pronounced positive εNd(t) values of 7.0 to 7.7, similar to some adakitic high-Mg andesites. The NEBPs are relatively Na-rich (Na2O/K2O>6) and display high abundances of P2O5 (~1.00%), TiO2 (~3.08%) and HFSE (e.g., Nb=9.53-10.27 ppm). Their Nd isotopic compositions (εNd(t)=6.8-8.0) are comparable to those of the HMDs. The PLAGs are metaluminous (A/CNK=0.84-0.89) and sodic (Na2O/K2O>10). Their depletion in HFSE (e.g., Nb, Ta) is consistent with 'SSZ-type' plagiogranite. Zircon LA-ICP-MS U-Pb dating yields an age of 932±7 Ma for the HMD, 916±6 Ma for the NEBP, and 902±5 Ma for the PLAG, respectively, indicating that they were products of early Neoproterozoic magmatism. The PLAGs exhibit relatively high zircon Hf isotopes and positive εHf(t) values of 11.0 to 16.2, consistent with their Nd isotopic data (εNd(t)=7.5-8.4). Such features are similar to those of oceanic plagiogranites in ophiolites and distinct from those of crust-derived granites. The PLAGs were most likely derived from partial melting of subducted oceanic crust in an active continental margin. Considering these results in the context of the regional geology, we suggest that a slab window in the subducting oceanic crust between the Yangtze Block and Cathaysia Block was possibly the principal cause for the unique arc magmatism in the area. The upwelling asthenosphere below the slab window may have provided significant thermodynamic conditions.CHEN ZhiHong GUO KunYi DONG YongGuan CHEN Rong LI LongMing LIANG YiHong LI ChunHai YU XiMing ZHAO Ling XING GuangFu 2009Science China Earth Sciences2009,52,7:26
3Effect of annealing treatment on the structural, optical, and electrical properties of Al-doped ZnO thin films显示文摘Highly conductive and transparent Al-doped ZnO (AZO) thin films were prepared from a zinc target containing Al (1.5 wt.%) by direct current (DC) and radio frequency (RF) reactive magnetron sputtering. The structural, optical, and electrical properties of AZO films as-deposited and submitted to annealing treatment (at 300 and 400°C, respectively) were characterized using various techniques. The experimental results show that the properties of AZO thin films can be further improved by annealing treatment. The crystallinity of ZnO films improves after annealing treatment. The transmittances of the AZO thin films prepared by DC and RF reactive magnetron sputtering are up to 80% and 85% in the visible region, re- spectively. The electrical resistivity of AZO thin films prepared by DC reactive magnetron sputtering can be as low as 8.06 × 10?4 ??cm after annealing treatment. It was also found that AZO thin films prepared by RF reactive magnetron sput- tering have better structural and optical properties than that prepared by DC reactive magnetron sputtering.LI Li FANG Liang CHEN Ximing LIU Gaobin LIU Jun YANG Fengfan FU Guangzong KONG Chunyang 2007Rare Metals2007,26,3:11
4Plants water status of the shelterbelt along the Tarim Desert Highway显示文摘The plant water consumption and irrigation management are the core issue of the sustainable growing of the Tarim Desert Highway shelterbelt in the hyperaride Taklimakan Desert. The stem sap flow, water status and water consumption of shelterbelt plants were studied, then, the issue of the water save in the process of shelterbelt irrigation management was discussed by measuring the sap flow of shelterbelt plants with a stem sap flow gauge. The stem sap flow exhibited a distinct diurnal course with maximum values between 10:00 and 15:00, and minimum values between 00:00 and 03:00. Generally, sap flow was lower at night than during the day. The daily average stem sap flow of Calligonum arborescens, Tamarix ramosissima and Haloxylon ammodendron (diameter 1.9―2.0 cm) was 67.2 g·h-1, 77.05 g·h-1 and 61.54 g·h-1 respectively. The sap flow was influenced by environmental factors, and the solar radiation, wind velocity, temperature and relative humidity were significantly correlative with plant stem sap flow. The annual water consumption of 8-a Calligonum arborescens, Tamarix ramosissima and Haloxylon ammodendron was 1937.80 kg, 1253.39 kg and 1026.96 kg, while daily average water consumption was 9.69 kg, 6.27 kg and 5.13 kg respectively. Under drip irrigation, soil moisture content of the shelterbelt in different months indicated no obvious fluctuation, and soil moisture was adequate. The predawn and midday plant water potential reflected that the plant water status was in good conditions. There is still some water-saving space if optimizing the present water management, integrating water resources conservation and protection performance.XU Hao ZHANG XiMing YAN HaiLong LIANG ShaoMin SHAN LiShan 2008Chinese Science Bulletin2008,53,S2:5
5Holistic Innovation:An Emerging Innovation Paradigm显示文摘This paper systematically reviews the current typical innovation paradigms worldwide and their shortcomings.Based on eastern wisdom and best innovation practices,this paper introduces a new paradigm of innovation,holistic innovation(HI).It provides a definition and theoretical framework for HI,discusses its connotations,and summarizes the theoretical contribution and policy implications.HI is total and collaborative innovation driven by strategic vision.This new innovation paradigm is a complex of strategic innovation,collaborative innovation,total innovation,and open innovation,which reflects wisdom from the Chinese context and Eastern culture.The four core elements of holistic innovation,“strategic,”“total,”“open,”and“collaborative,”are inter-related with an organic integration with the helix of HI.HI is an original innovation paradigm that conforms to the needs of firms'technological innovation management in the strategic innovation era and supports the implementation of the Innovation-Driven Development Strategy.It also helps China's enterprises build global innovation leadership and improves national innovation ability.Finally,it optimizes the innovation policy design and action mindset to achieve global peace and sustainable development.Jin Chen Ximing Yin Liang Mei 2018International Journal of Innovation Studies2018,2,1:3
6Physiological response of natural C.taklimakanensis B.R.Pan et G.M.Shen to unconfined groundwater in the hinterland of the Taklimakan Desert显示文摘Calligonum. taklimakanensis B.R.Pan et G.M.Shen is an indigenous species that grows in the Taklimakan Desert. This study shows the relationship between C.taklimakanensis B.R.Pan et G.M.Shen and water conditions in the hinterland of the desert. The results show that: (1) Depth of water table is an important factor that affects water potential (ψp, ψA), osmotic potential (ψsat, ψtlp), relative water content (RWCtlp, ROWCtlp), and transpiration rate. (2) The degree of mineralization has a significant impact on the water potential of plants. A high degree of mineralization can strongly reduce plant productivity. (3) C. taklimakanensis B.R.Pan et G.M.Shen reduces the temperature of assimilation sticks through a high transpiration rate and maintains relatively high water content to adapt to drought and hot weather conditions in the hinterland of the desert. In addition, C. taklimakanensis B.R.Pan et G.M.Shen adapts to the water status in the desert through self-regulation or even sacrificing productivity.LIANG ShaoMin YAN HaiLong ZHANG XiMing XIE TingTing ZHU JunTao ZHANG ZhongWu 2008Chinese Science Bulletin2008,53,S2:2
7Collective rotations of fission isomers in actinide nuclei显示文摘Using the total-Routhian-surface(TRS)method,the rotational behaviors of fission isomers in the second well of actinide nuclei234 242U,236 244Pu and238 246Cm were investigated.The pairing-deformation-frequency self-consistent TRS calculations reproduced reasonably the experimental moments of inertia extracted from spectroscopic data.It is calculated that,in these largelyelongated(β2≈0.65 andβ4≈0.03)fission isomers,theν12[981]neutron andπ12+[651]proton align simultaneously at rotational frequencyω≈0.4 0.6 MeV(corresponding to spin I≈80),which leads to clear upbending in moments of inertia(MoI’s).Our calculations have indicated that the hexadecapole deformationβ4influenced significantly the frequency of the rotational alignment of the proton12+[651]orbit.XIE KePing KE WeiYao LIANG WuYang FU XiMing JIAO ChangFeng PEI JunChen XU FuRong 2014Science China(Physics,Mechanics & Astronomy)2014,57,2:2
8A multi-functional binder for high loading sulfur cathode显示文摘Lithium sulfur(Li-S)batteries are the promising power sources,but their commercialization is significantly impeded by poor energy-storage functions at high sulfur loading.Here we report that such an issue can be effectively addressed by using a mussel-inspired binder comprised of chitosan grafted with catecholic moiety for sulfur cathodes.The resulting sulfur cathodes possess a high loading up to 12.2 mg cm-2 but also exhibit one of the best electrochemical properties among their counterparts.The excellent performances are attributed to the strong adhesion of the binder to sulfur particles,conducting agent,current collector,and polysulfide.The versatile adhesion effectively increases the sulfur loading,depresses the shuttle effect,and alleviates mechanical pulverization during cycling processes.The present investigation offers a new insight into high performance sulfur cathodes through a bio-adhesion viewpoint.Ying Chu Ning Chen Ximing Cui Anmin Liu Liang Zhen Qinmin Pan 2020Journal of Energy Chemistry2020,29,7:2

10Photosynthesis responses of endemic shrubs of Taklimakan Desert to adverse temperature, humidity and radiation显示文摘Under the native habitat conditions, the seasonal gas exchange characteristics of two natural endemic plant species, Calligonum taklimakanensis B.R. Pan & G.M. Shen and Tamarix taklamakanensis M.T. Liu, which are located in the hinterland of the Taklimakan Desert, are measured and compared by Li-6400 photosynthesis system. The results indicate that temperature (℃), solar radiation (PAR), soil water content (SWC), and other environmental factors have obvious seasonal variations and the gas exchange characteristics of two plants have different changes in different growing seasons. For C. taklimakanensis, both in July and September, its daily changes of net photosynthetic rate tend to be obvious double peak curve, but in July its peak appeared earlier. Besides its maximum net photosynthetic rate (Pmax), apparent quantum efficiency (Φ ), range of effective photosynthetic radiation significantly less than that in September. Moreover, its water use efficiency (WUE) in July was also lower than that in September due to the higher transpiration rate (Tr ). For T. taklamakanensis, although its daily change of net photosynthetic rate is a single peak curve in September, its peak time has not changed, and except that its WUE is higher in September like C. taklimakanensis, the maximum net photosynthetic rate (Pmax), apparent quantum effi- ciency (Φ ), light saturation point, and range of effective photosynthetic radiation has not changed or slightly declined. That is to say C. taklimakanensis select a season that habitat was better (like September) to progress relative effectively photosynthesis accumulation, in contrast, T. taklamakanensis still keep a relatively stable photosynthesis rate in different growth seasons. The difference of gas exchange characteristics of the two plants in different seasons shows that adaptation strategies of the two plants to extreme conditions in desert are different. Besides, both the higher photosynthetic accumulation rate and the higher water use efficiency in September also indicate that these two endemic desert shrubs possess the abilities and strategies to make the best of limited natural resources.YAN HaiLong LIANG ShaoMin ZHANG XiMing WANG WeiHua MA JianBing ZHU JunTao 2008Chinese Science Bulletin2008,53,S2:2

19Increased rigidly triaxial deformations in neutron-rich Mo, Ru isotopes显示文摘Pairing-deformation-frequency self-consistent crankingWoods-Saxon model is employed to investigate the triaxiality in the ground states of the neutron-rich even-even Mo, Ru isotopes. Deformation evolutions and transition probabilities have been studied, giving the triaxial shapes in their ground states. The kinematic moments of inertia have been calculated to illustrate the gradually rigid deformation. To understand the origin of the asymmetry shape in this region, we analyze the evolution of single-particle orbits with changing γ deformation. The present calculations reveal the importance of the triaxial deformation in describing not only static property, but also rotational behaviors in this mass region, providing significant probes into the shell structure around.WuYang Liang ChangFeng Jiao FuRong Xu XiMing Fu 2016Science China(Physics,Mechanics & Astronomy)2016,59,9:0
20肠系膜巨大神经纤维瘤1例报道(英文)显示文摘We presented a case of giant neurofibromas arising from the jejunal mesentery of a 52-year-old man. The patient presented with epigastric fullness,and decrease of food intake,but without stigmata of neurofibromatosis-1. Ultrasonography,computed tomography (CT) and MR imaging revealed two large masses in the abdomen extending to the pelvis. Total resection of the tumors together with corresponding segments of intestines was performed. Histological examination and immunocytochemistry for S-100 protein confirmed the masses to be multiple neurofibromas of the mesentery. We also discussed the clinical features,and treatment approaches of similar cases in literatures.Youhong Ding Xiangyang Li Liang Qiu Ximing Xu Houbing Liu Guangjin Yuan 2010The Chinese-German Journal of Clinical Oncology2010,9,6:0
