1Spatial-temporal pattern changes of main agriculture natural disasters in China during 1990-2011显示文摘China is a disaster prone country, and a comprehensive understanding of change of disasters is very important for China's agricultural development. In this study, statistical techniques and geographic information system tools are employed to quantify the main agriculture disasters changes and effects on grain production in China during the period of 1990–2011. The results show that China's grain production was severely affected by disasters including drought, flood, hail, frost and typhoon. The annual area covered by these disasters reached up to 48.7×106 ha during the study period, which accounted for 44.8% of the total sown area, and about 55.1% of the per unit area grain yield change was caused by disasters. In addition, all of the disasters showed high variability, different changing trends, and spatial distribution. Drought, flood, and hail showed significantly decreasing trends, while frost and typhoon showed increasing trends. Drought and flood showed gradual changes and were distributed across the country, and disasters became more diversified from north to south. Drought was the dominated disaster type in northern China, while flood was the most important disaster type in the southern part. Hail was mainly observed in central and northern China, and frost was mainly distributed in southern China. Typhoon was greatly limited to the southeast coast. Furthermore, the resilience of grain production of each province was quite different, especially in several major grain producing areas, such as Shandong, Liaoning, Jilin and Jiangsu, where grain production was seriously affected by disasters. One reason for the difference of resilience of grain production was that grain production was marginalized in developed provinces when the economy underwent rapid development. For China's agricultural development and grain security, we suggest that governments should place more emphasis on grain production, and invest more money in disaster prevention and mitigation, especially in the major grain producing provinces.DU Xindong JIN Xiaobin YANG Xilian YANG Xuhong XIANG Xiaomin 2015Journal of Geographical Sciences2015,25,4:8
2Clinical practices s of Traditional Chinese Medicine for acute upper respiratory tract infection in children显示文摘OBJECTIVE:To develop Clinical practice s of Traditional Chinese Medicine(TCM) for acute upper respiratory tract infection(AURI) in children;TCM is usedalone or administered together with antibiotics.METHODS:Under the guidance of evidence-based medicine concept,in strict accordance with the rules of international s development,as well as on the basis of evidence of clinical research of TCM,the s solicited opinions from clinical experts and methodologists in TCM and Western Medicine.GRADE standard was applied to form experts' consensus.RESULTS:The s standardized classification of TCM patterns and TCM treatments in children with AURI,including prescription,Chinese patent medicine,non-drug treatment and prevention.CONCLUSION:Follows the principle of 'evidence based,consensus supplemented,and experience referred',these s were formulated,but the quality of evidence of included studies were relatively low.Further refinement of the s should be needed as deeper clinical studies as available in future.Rong Ping Li Li Zhang Xilian Liu Quanhui Yan Huimin Xin Deli Xue Zheng Ren Xianqing Wu Zhenqi Ma Rong Zhang Junhua 2018Journal of Traditional Chinese Medicine2018,38,4:7
3Identification of an Early–Middle Jurassic oxidized magmatic belt,south Gangdese,Tibet,and geological implications显示文摘The south Gangdese region is the site of subduction of the Neo-Tethys and subsequent continental collision. Compared with widespread Cretaceous and Cenozoic magmatism, Early–Middle Jurassic magmatic rocks and related deposits are rarely reported. Our work identified a >200 km long felsic rock belt associated with Cu mineralization in the south Gangdese region. We report here zircon U–Pb ages, zircon Ce^(4+)/Ce^(3+)values, and mineral assemblages of two Cu mineralized intrusions within the belt. A hornblende granite and a diorite porphyry were emplaced at 177.3 Ma and 166.3 Ma, respectively.Geological occurrence and magmatic hematite–magnetite–chalcopyrite intergrowths suggest that Cu mineralization formed coeval with Jurassic intrusions. Mineralized intrusions have high zircon Ce^(4+)/Ce^(3+)and EuN/Eu?N ratios, and hematite–magnetite intergrowths, suggesting their parent magmas were highly oxidized. Hornblende is common and primary fluid inclusions are found in titanite and apatite,indicating their parent magmas were water-saturated and exsolved volatile phases at early stage of magmatic evolution. Those magma characters contribute to the formation of porphyry Cu deposits. Given that majority subduction-related porphyry Cu systems have been eroded following uplift and denudation, the well-preserved Early–Middle Jurassic Cu mineralized igneous rocks in south Gangdese are favorable prospecting targets for subduction-related porphyry Cu deposits.Yinqiao Zou Xilian Chen Wenting Huang Jian Zhang Huaying Liang Jifeng xu Ling Chen 2017Science Bulletin2017,62,12:7
4Research on colored lyotropic liquid crystals显示文摘Splendidly colored lyotropic liquid crystals formed in the ternary system of a novel cationic surfactant, 3-p-nonylphenoxy-2-hydroxypropyl trimethyl ammonium bromide (NPTAB)-n-butanol-water system, had been ob-served under polarized light microscope. Small-angle X-ray scattering (SAXS), 2H (deuterium) quadrupolar splitting (2H NMR) were employed to confirm the structures of these liq-uid crystals. The structural transformation of these special lyotropic liquid crystals had been confirmed by differential scanning calorimetry (DSC). The influences of liquid crystal film thickness, temperature and conserving time on the color of liquid crystals have been investigated. It is also theoreti-cally discussed for forming and changing of liquid crystal color.WEI Xilian YIN Baolin SUN Dezhi LIU Jie WANG Zhongni LI Ganzuo 2005Chinese Science Bulletin2005,50,15:2

17Three-dimensional Ag/carbon nanotube-graphene foam for high performance dendrite free lithium/sodium metal anodes显示文摘Although lithium metal and sodium metal are promised as ideal anodes for lithium ion batteries(LIBs)and sodium ion batteries(SIBs),they still suffer from inevitable dendrite growth.In light of this,silver nanoparticles(Ag NPs)are sputtered onto three-dimensional carbon nanotube decorated graphene foam(3D CNT-GF)to construct superior 3D Ag/CNT-GF composite matrix for lithium metal anodes(LMAs)and sodium metal anodes(SMAs).With this design,lithiophilic/sodiophilic Ag NPs could provide favorable sites to guide Li/Na metal nucleation and growth,thus leading to low nucleation overpotentials,high Coulombic efficiency and long cycle performance.Accordingly,3D Ag/CNT-GF electrodes can stably cy-cle for 1000 and 750 cycles at 3 mA cm^(−2)with 1 mAh cm^(−2)for SMAs and LMAs,respectively.More attractively,it can also stably sustain 300 cycles(SMAs)and 500 cycles(LMAs)at a large current den-sity of 5 mA cm^(−2)with 1 mAh cm^(−2).The excellent electrochemical performance can be attributed to the lithiophilic/sodiophilic electrode surface,3D porous electrode structure and the dendrite-free mor-phology as demonstrated by ex-situ scanning electron microscopy(SEM)and in-situ optical microscopy analyses.Furthermore,full cells based on Na@3D Ag/CNT-GF||Na 3 V 2(PO 4)3@carbon(NVP@C)and Li@3D Ag/CNT-GF||LiFePO 4(LFP)could deliver highly reversible capacities of 90.1 and 106.4 mAh g^(−1),respec-tively,at 100 mA g^(−1)after 200 cycles for SIBs and LIBs,respectively.This work demonstrates a novel 3D Ag/CNT-GF matrix for boosting Li/Na deposition stability for their future applications.Bofang Tian Zhenxin Huang Xilian Xu Xiehong Cao Hui Wang Tingting Xu Dezhi Kong Zhuangfei Zhang Jie Xu Jinhao Zang Xinjian Li Ye Wang 2023Journal of Materials Science & Technology2023,,1:1
