| 1 | Characteristics of Cd isotopic compositions and their genetic significance in the lead-zinc deposits of SW China显示文摘Up to now,the evaporation and condensation,as well as the biological absorption and inorganic absorptions,have been proved to be major factors in Cd isotope fractionation.And Cd isotopes have been widely applied in studies on the universal evolution and marine environment and so on.However,only a few researches have been conducted in applying Cd isotopes to trace the source of metallogenic material and the evolution of the ore-forming fluid in a complex mineralization environment,especially in a hydrothermal ore-formation system.We measured the Cd isotopic compositions of sphalerite,galena,and ores from five lead-zinc deposits in SW China,and found that the 114/110Cd values varied from 1.53‰to 0.34‰,with a total range of1.87‰,which is greater than most of measured geological samples.Meanwhile,through contrasting the Cd content with Cd isotopic compositions of different deposits,it may be concluded that different genetic lead-zinc deposits have different Cd content and isotopic compositions,which could be a tool for the studies on the origin of ore deposits.Also,the biomineralization and crystal fractionation may also result in Cd isotope fractionation.In a word,although the research of Cd isotopes is presently at the preliminary stage(especially in hydrothermal ore-formation system),this study demonstrated that Cd isotopes can give a clue in tracing the evolution of ore-forming fluid and metallogenic environment. | ZHU ChuanWei WEN HanJie ZHANG YuXu FAN HaiFeng FU ShaoHong XU Juan QIN TingRong | 2013 | Science China Earth Sciences2013，56，12： | 14 |
| 2 | Major advances in studies of the physical geography and living environment of China during the past 70 years and future prospects显示文摘The natural environment provides material essentials for human survival and development. The characteristics,processes, regional differentiation and forcing mechanisms of the elements of the natural environment(e.g. geomorphology,climate, hydrology, soil, etc.) are the main objects of research in physical geography. China has a complex natural environment and huge regional differentiation and therefore it provides outstanding reserach opportunities in physical geography. This review summarizes the most important developments and the main contributions of research in the physical geography and human living environment in China during the past 70 years. The major topics addressed are the uplift of the Tibetan Plateau and the evolution of its cryosphere, the development of fluvial systems, the acidification of the vast arid region of the Asian interior, variations in the monsoon and westerly climate systems on multiple timescales, the development of lakes and wetlands, the watershed system model, soil erosion, past human-environment interactions, biogeography, and physical geographic zonality. After briefly introducing international research developments, we review the history of research in physical geography in China, focusing on the major achievements and major academic debates, and finally we summarize the status of current research and the future prospects. We propose that in the context of the national demand for the construction of an ecological civilization, we should make full use of the research findings of physical geography, and determine the patterns and mechanisms of natural environmental processes in order to continue to promote the continued contribution of physical geography to national development strategies, and to further contribute to the theory of physical geography from a global perspective. | Fahu CHEN Bojie FU Jun XIA Duo WU Shaohong WU Yili ZHANG Hang SUN Yu LIU Xiaomin FANG Boqiang QIN Xin LI Tingjun ZHANG Baoyuan LIU Zhibao DONG Shugui HOU Lide TIAN Baiqing XU Guanghui DONG Jingyun ZHENG Wei YANG Xin WANG Zaijun LI Fei Wang Zhenbo HU Jie WANG Jianbao LIU Jianhui CHEN Wei HUANG Juzhi HOU Qiufang CAI Hao LONG Ming JIANG Yaxian HU Xiaoming FENG Xingguo MO Xiaoyan YANG Dongju ZHANG Xiuhong WANG Yunhe YIN Xiaochen LIU | 2019 | Science China Earth Sciences2019，62，11： | 11 |

| 4 | Nitrogen-doped carbon encapsulated in mesoporous TiO2 nanotubes for fast capacitive sodium storage显示文摘Controllable synthesis of insertion-type anode materials with beneficial micro-and nanostructures is a promising approach for the synthesis of sodium-ion storage devices with high-reactivity and excellent electrochemical performance.In this study,we developed a sacrificial-templating route to synthesize TiO_(2)@N-doped carbon nanotubes(TiO_(2)@NC-NTs)with excellent electrochemical performance.The asprepared mesoporous TiO_(2)@NC-NTs with tiny nanocrystals of anatase TiO_(2) wrapped in N-doped carbon layers showed a well-defined tube structure with a large specific surface area of 198 m^(2) g^(-1) and a large pore size of~5 nm.The TiO_(2)@NC-NTs delivered high reversible capacities of 158 m A h g^(-1) at 2 C(1 C=335 m A g^(-1))for 2200 cycles and 146 m A h g^(-1) at 5 C for 4000 cycles,as well as an ultrahigh rate capability of up to 40 C with a capacity of 98 m A h g^(-1).Even at a high current density of 10 C,a capacity of 138 m A h g^(-1) could be delivered over 10,000 cycles.Thus,the synthesis of mesoporous TiO_(2)@NC-NTs was demonstrated to be an efficient approach for developing electrode materials with high sodium storage and long cycle life. | Baosong Li Shoaib Anwer Xinhua Huang Shaohong Luo Jing Fu Kin Liao | 2021 | Journal of Energy Chemistry2021，30，4： | 1 |
| 5 | THE REALIZATION OF THE PPP AUTOFOCUS METHOD IN PFA FOR SPOTLIGHT MODE SAR IMAGING显示文摘This paper first studies the phase errors for fine-resolution spotlight mode SAR imaging and decomposes the phase errors into two kinds, one is caused by translation and the other by rotation. Mathematical analysis and computer simulations show the above mentioned motion kinds and their corresponding damages on spotlight mode SAR imaging. Based on this analysis, a single PPP is introduced for spotlight mode SAR imaging with the PFA on the assumption that relative rotation between APC and imaged scene is uniform. The selected single point is used first to correct the quadratic and higher order phase errors and then to adjust the linear errors. After this compensation, the space-invariant phase errors caused by translation are almost corrected. Finally results are presented with the simulated data. | Fu Wenxian Hong Wen Li Shaohong (Dept. of Electronic Eng.

| 6 | Physiological and genome-wide gene expression analyses of cold-induced leaf rolling at the seedling stage in rice(Oryza sativa L.)显示文摘Leaf rolling and discoloration are two chilling-injury symptoms that are widely used as indicators for the evaluation of cold tolerance at the seedling stage in rice. However, the difference in cold-response mechanisms underlying these two traits remains unknown. In the present study, a cold-tolerant rice cultivar, Lijiangxintuanheigu, and a cold-sensitive cultivar, Sanhuangzhan-2, were subjected to low-temperature treatments and physiolog-ical and genome-wide gene expression analyses were conducted. Leaf rolling occurred at temperatures lower than 11℃, whereas discoloration appeared at moderately low temperatures such as 13℃. Chlorophyll contents in both cultivars were significantly decreased at 13℃, but not altered at 11℃. In contrast, the relative water content and relative electrolyte leakage of both cultivars decreased significantly at 11℃, but did not change at 13℃. Expression of genes associated with calcium signaling and abscisic acid (ABA) degradation was significantly altered at 11℃ in comparison with 25℃ and 13℃. Numerous genes in the DREB, MYB, bZIP, NAC, Zinc finger, bHLH, and WRKY gene families were differentially expressed. Many aquaporin genes and the key genes in trehalose and starch synthesis were down regulated at 11℃ in comparison with 25℃ and 13℃. These results suggest that the two chilling injury symptoms are temperature-specific and are controlled by different mechanisms. Cold-induced leaf rolling is associated with calcium and ABA signaling pathways and is regulated by multiple transcriptional regulators. The suppression of aquaporin genes and reduced accumulation of soluble sugars under cold stress results in a reduction in cellular water potential and consequently leaf rolling. | Jingfang Dong Junliang Zhao Shaohong Zhang Tifeng Yang Qing Liu Xingxue Mao Hua Fu Wu Yang Bin Liu | 2019 | The Crop Journal2019，7，4： | 1 |
| 7 | Oxygen-vacancy-containing cerium oxide nanoparticle-decorated nanonetwork-structured carbon toward high-performance lithium–sulfur batteries显示文摘Lithium-sulfur(Li-S)batteries have been regarded as promising next-generation energy-storage devices owing to their inherently high theoretical energy density.Unfortunately,the poor capacity and cycling life caused by severe polysulfide shuttle effect and sluggish redox kinetics in sulfur cathodes greatly impede the practical application of Li-S batteries.Herein,a new class of nanonetworkstructured carbon decorated with oxygen-vacancy-containing cerium oxide nanoparticles(NSC-CeO_(2−x)),in which carbon skeleton is composed of highly conductive carbon nanotube core welded by hybrid carbon shell,has been developed via one-step heating treatment of hybrid molecular brush and further employed as functional interlayer to modify separator of Li-S battery.Owing to the synergistic effect of the highly active CeO_(2−x)nanoparticles and the threedimensional carbon nanonetwork in enhancing the preservation of the soluble polysulfides and boosting the redox kinetics of sulfur species,the NSC-CeO_(2−x)significantly promotes the electrochemical performance of sulfur cathode.As a result,the as-constructed Li-S batteries exhibit an ultrahigh initial sulfur utilization of 92.9%and an extremely large capacity of 751mA h g^(−1) at a high rate of 5 C.Remarkably,a stable capacity of 728 mA h g^(−1)over 300 cycles at 1 C is also achieved. | Chuanfa Li Pengwei Ma Shenghao Lin Zongheng Cen Junlong Huang Yin Cui Shimei Li Shaohong Liu Ruowen Fu Dingcai Wu | 2023 | SusMat2023，3，1： | 0 |
| 8 | Labor Transfer:A Catalyst or Anticatalyst for Poverty Alleviation?--A study based on a survey of 237 rural households in Yi communities in Liangshan显示文摘This paper takes income and“two no worries and three guarantees”(rural poor people have no worry about food and clothing and have access to compulsory education,basic medical services,and safe housing)as two essential indexes,and is based on data collected from a survey of 237 rural households living below the poverty level in Yi communities in Liangshan.Through case studies and positive analysis,we explored the impact of labor transfer on poverty alleviation.We found that the following factors contribute to a double paradox of labor service-enabled poverty alleviation:An income growth trend which prioritizes“external income”(from urban work)over“internal income”(from an agricultural business),restrictions by performance indexes,as well as a lack of public services in rural areas.Although labor transfer can help rural households increase household income and non-agricultural income and reduce poverty within a short period of time,it can hardly promote agricultural businesses through non-agricultural employment and thereby help poverty-stricken rural households permanently alleviate poverty.Although labor transfer can exacerbate various issues facing poverty-stricken households(such as a delay in housing construction,school drop-out rates and health risks for the elderly),it can also play a positive role in raising the profile of farmers and improving rural education and living environments.Based on this study,we propose continuing the supply-side reform in the labor market,implementing differentiated poverty alleviation policies,improving the existing mechanism for poverty alleviation assessment,establishing rural public services,and launching a corresponding multi-channel financing mechanism. | Zhang Lei Fu Shaohong Wu Lingwei(翻译) | 2020 | Contemporary Social Sciences2020，5，6： | 0 |
| 9 | DNA repair-and nucleotide metabolism-related genes exhibit differential CHG methylation patterns in natural and synthetic polyploids (Brassica napus L.)显示文摘Polyploidization plays a crucial role in the evolution of angiosperm species.Almost all newly formed polyploids encounter genetic or epigenetic instabilities.However,the molecular mechanisms contributing to genomic instability in synthetic polyploids have not been clearly elucidated.Here,we performed a comprehensive transcriptomic and methylomic analysis of natural and synthetic polyploid rapeseeds(Brassica napus).Our results showed that the CHG methylation levels of synthetic rapeseed in different genomic contexts(genes,transposon regions,and repeat regions)were signi fi cantly lower than those of natural rapeseed.The total number and length of CHG-DMRs between natural and synthetic polyploids were much greater than those of CG-DMRs and CHH-DMRs,and the genes overlapping with these CHG-DMRs were signi fi cantly enriched in DNA damage repair and nucleotide metabolism pathways.These results indicated that CHG methylation may be more sensitive than CG and CHH methylation in regulating the stability of the polyploid genome of B.napus.In addition,many genes involved in DNA damage repair,nucleotide metabolism,and cell cycle control were significantly differentially expressed between natural and synthetic rapeseeds.Our results highlight that the genes related to DNA repair and nucleotide metabolism display differential CHG methylation patterns between natural and synthetic polyploids and reveal the potential connection between the genomic instability of polyploid plants with DNA methylation defects and dysregulation of the DNA repair system.In addition,it was found that the maintenance of CHG methylation in B.napus might be partially regulated by MET1.Our study provides novel insights into the establishment and evolution of polyploid plants and offers a potentialidea for improving the genomic stability of newly formed Brassica polyploids. | Liqin Yin Zhendong Zhu Liangjun Huang Xuan Luo Yun Li Chaowen Xiao Jin Yang Jisheng Wang Qiong Zou Lanrong Tao Zeming Kang Rong Tang Maolin Wang Shaohong Fu | 2021 | Horticulture Research2021，8，1： | 0 |
