| 1 | Ideotype root architecture for efficient nitrogen acquisition by maize in intensive cropping systems显示文摘The use of nitrogen(N) fertilizers has contributed to the production of a food supply sufficient for both animals and humans despite some negative environmental impact.Sustaining food production by increasing N use efficiency in intensive cropping systems has become a major concern for scientists,environmental groups,and agricultural policymakers worldwide.In high-yielding maize systems the major method of N loss is nitrate leaching.In this review paper,the characteristic of nitrate movement in the soil,N uptake by maize as well as the regulation of root growth by soil N availability are discussed.We suggest that an ideotype root architecture for efficient N acquisition in maize should include(i) deeper roots with high activity that are able to uptake nitrate before it moves downward into deep soil;(ii) vigorous lateral root growth under high N input conditions so as to increase spatial N availability in the soil;and(iii) strong response of lateral root growth to localized nitrogen supply so as to utilize unevenly distributed nitrate especially under limited N conditions. | MI GuoHua,CHEN FanJun,WU QiuPing,LAI NingWei,YUAN LiXing & ZHANG FuSuo* Key Laboratory of Plant Nutrition,MOA Key Laboratory of Plant-Soil Interaction,MOE College of Resources and Environmental Science,China Agricultural University,Beijing 100193,China | 2010 | Science China(Life Sciences)2010，53，12： | 35 |
| 2 | Extending the CONSORT Statement to moxibustion显示文摘The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM. | Chung-wah Cheng Shu-fei Fu Qing-hui Zhou Tai-xiang Wu Hong-cai Shang Xu-dong Tang Zhi-shun Liu Jia Liu Zhi-xiu Lin Lixing Lao Ai-ping Lü Bo-li Zhang Bao-yan Liu Zhao-xiang Bian | 2013 | Journal of Integrative Medicine2013，11，1： | 27 |
| 3 | Evaluation of the yield and nitrogen use efficiency of the dominant maize hybrids grown in North and Northeast China显示文摘Breeding high-yielding and nutrient-efficient cultivars is one strategy to simultaneously resolve the problems of food security,resource shortage,and environmental pollution.However,the potential increased yield and reduction in fertilizer input achievable by using high-yielding and nutrient-efficient cultivars is unclear.In the present study,we evaluated the yield and nitrogen use efficiency(NUE) of 40 commercial maize hybrids at five locations in North and Northeast China in 2008 and 2009.The effect of interaction between genotype and nitrogen(N) input on maize yield was significant when the yield reduction under low-N treatment was 25%-60%.Based on the average yields achieved with high or low N application,the tested cultivars were classified into four types based on their NUE:efficient-efficient(EE) were efficient under both low and high N inputs,high-N efficient(HNE) under only high N input,low-N efficient(LNE) under only low N input,and nonefficient-nonefficient under neither low nor high N inputs.Under high N application,EE and HNE cultivars could potentially increase maize yield by 8%-10% and reduce N input by 16%-21%.Under low N application,LNE cultivars could potentially increase maize yield by 12%.We concluded that breeding for N-efficient cultivars is a feasible strategy to increase maize yield and/or reduce N input. | CHEN FanJun FANG ZenGuo GAO Qiang YE YouLiang JIA LiangLiang YUAN LiXing MI GuoHua ZHANG FuSuo | 2013 | Science China(Life Sciences)2013，56，6： | 27 |
| 4 | Root growth in response to nitrogen supply in Chinese maize hybrids released between 1973 and 2009显示文摘Root growth has a fundamental role in nitrogen (N) use efficiency.Nevertheless,little is known about how modern breeding progress has affected root growth and its responses to N supply.The root and shoot growth of a core set of 11 representative Chinese maize (Zea mays L.) hybrids released between 1973 and 2009 were investigated under high N (4 mmol L?1,HN) and low N (0.04 mmol L?1,LN) levels in a solution culture system.Compared with LN,HN treatment decreased root dry weight (RDW),the root:shoot ratio (R/S),and the relative growth rate for root dry weight (RGRroot),but increased the total root length (TRL) and the total lateral root length (LRL).The total axial root length (ARL) per plant was reduced under HN,mostly in hybrids released before the 1990s.The number of seminal roots (SRN) was largely unaffected by different N levels.More recently released hybrids showed higher relative growth rates in the shoot under both HN and LN.However,the roots only showed increased RGR under HN treatment.Correspondingly,there was a positive linear relationship with the year of hybrid release for TRL,LRL and ARL under HN treatment.Together,these results suggest that while shoot growth of maize has improved,its root growth has only improved under high N conditions over the last 36 years of selective breeding in China.Improving root growth under LN conditions may be necessary to increase the N use efficiency of maize. | WU QiuPing CHEN FanJun CHEN YanLing YUAN LiXing ZHANG FuSuo MI GuoHua | 2011 | Science China(Life Sciences)2011，54，7： | 15 |
| 5 | The role of maize root size in phosphorus uptake and productivity of maize/faba bean and maize/wheat intercropping systems显示文摘Interspecific root/rhizosphere interactions affect phosphorus (P) uptake and the productivity of maize/faba bean and maize/wheat intercropping systems. The aim of these experiments was to determine whether manipulation of maize root growth could improve the productivity of the two intercropping systems. Two near isogenic maize hybrids (the larger-rooted T149 and smaller-rooted T222) were intercropped with faba bean and wheat, under conditions of high- and low-P availability. The larger-rooted T149 showed greater competitive ability than the smaller-rooted T222 in both maize/faba bean and maize/wheat intercropping systems. The higher competitive ability of T149 improved the productivity of the maize/faba bean intercropping system in P-sufficient conditions. In maize/wheat intercropping systems, root growth, shoot biomass, and P uptake of maize were inhibited by wheat, regardless of the P-supply. Compared with T222, the larger-rooted T149 suffered less in the intercropping systems. The total biomass of the maize/wheat intercropping system was higher for wheat/T149 than for wheat/T222 under low-P conditions. These data suggested that genetic improvement of maize root size could enhance maize growth and its ability to compete for P resources in maize/faba bean and maize/wheat intercropping systems. In addition, depending on the P availability, larger maize roots could increase the productivity of intercropping systems. | ZHANG YiKai CHEN FanJun LI Long CHEN YanHua LIU BingRan ZHOU YuLing YUAN LiXing ZHANG FuSuo MI GuoHua | 2012 | Science China(Life Sciences)2012，55，11： | 13 |
| 6 | Review of the fabrication and application of porous materials from silicon-rich industrial solid waste显示文摘Porous materials have promise as sound insulation, heat barrier, vibration attenuation, and catalysts. Most industrial solid wastes, such as tailings, coal gangue, and fly ash are rich in silicon. Additionally, a high silicon content waste is a potential raw material for the syn- thesis of silicon-based, multi-porous materials such as zeolites, mesoporous silica, glass-ceramics, and geopolymer foams. Representative sil- icon-rich industrial solid wastes (SRISWs) are the focus of this mini review of the processing and application of porous silicon materials with respect to the physical and chemical properties of the SRISW. The transformation methods of preparing porous materials from SRISWs are summarized, and their research status in micro-, meso-, and macro-scale porous materials are described. Possible problems in the application of SRISWs and in the preparation of functional porous materials are analyzed, and their development prospects are discussed. This review should provide a typical reference for the recycling and use of industrial solid wastes to develop sustainable “green materials.” | Chao Miao Lixing Liang Fan Zhang Shumei Chen Kaixuan Shang Jinlong Jiang Yi Zhang Jing Ouyang | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，3： | 10 |
| 7 | NbN superconducting nanowire single photon detector with efficiency over 90% at 1550 nm wavelength operational at compact cryocooler temperature显示文摘The rapid development of superconducting nanowire single-photon detectors over the past decade has led to numerous advances in quantum information technology. The record for the best system detection efficiency at an incident photon wavelength of 1550 nm is 93%. This performance was attained from a superconducting nanowire single-photon detector made of amorphous WSi; such detectors are usually operated at sub-Kelvin temperatures. In this study, we first demonstrate superconducting nanowire single-photon detectors made of polycrystalline NbN with system detection efficiency of 90.2% for 1550-nm-wavelength photons at2.1 K, accessible with a compact cryocooler. The system detection efficiency saturated at 92.1% when the temperature was lowered to 1.8 K. We expect the results lighten the practical and high performance superconducting nanowire single-photon detectors to quantum information and other high-end applications. | WeiJun Zhang LiXing You Hao Li Jia Huang ChaoLin Lv Lu Zhang XiaoYu Liu JunJie Wu Zhen Wang XiaoMing Xie | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，12： | 9 |
| 8 | Do anogenital gland secretionsof giant panda code for their sexual ability?显示文摘To test the hypothesis of whether ano- genital gland secretions (AGS) of giant panda code for their sexual ability, we collected AGS samples of 11 male (5 adult and 6 subadult) and 14 female (7 adult and 7 subadult) captive giant pandas (Ailuro- poda melanoleuca) from China Research and Con- servation Center for the Giant Panda at Wolong, Si- chuan, China from 1994 to 2002. The samples were analyzed by GC and GC-MS. The GC results showed that male and female pandas shared 20 constituents with equal capacity factors in the AGS. Further GC-MS analyses showed that there were a total of 95 compounds in the AGS. Nine constituents for the males and three for the females differed significantly in relative abundances between sexually active and inactive individuals, but no clear division between sexually active and inactive pandas by hierarchical cluster analyses on the relative abundances of a subset of 56 compounds. However, we were able to separate different age groups of male pandas by the constituents of AGS. 14 compounds were found sig- nificantly and negatively, and 8 compounds positively, correlated with pandas’ age by year. Our results suggest that the information contained in the AGS of panda might not code for pandas’ sexual ability but might for their age. These results will be valuable for captive breeding and conservation in the wild. | LIU Dingzhen YUAN Hong TIAN Hong WEI Rongping ZHANG Guiquan SUN Lixing WANG Liwen SUN Ruyong | 2006 | Chinese Science Bulletin2006，51，16： | 7 |

| 10 | Male panda (Ailuropoda melanoleuca) urine contains kinship information显示文摘Chemical communication plays an important role in kin selection and mate choice in mammals. The covariance of odor-genes of rodents has been documented and kinship odor has been proposed and termed, yet little is known of the relationship between genetic relatedness and chemical composition of kinship odors. Giant pandas (Ailuropoda melanoleuca) rely substantially on chemical communication to mediate their social interactions. To examine the relationship between genetic relatedness and compounds in the urine/anogenital gland secretions, we compared the similarities between genetic relatedness and the chemical profiles of anogenital gland secretions and urine via lineage construction and GC-MS (gas chromatography and mass spectrometry). We found that information about kinship odors was present only in the urine of male adults in the mating season but absent in the non-mating season. Adult females and all sub-adults did not have such kinship odors in either mating or non-mating season. Therefore, kinship odor in the panda was contingent on age, sex, and season. This is the first report about the condition-dependent expression of kinship odor, which may have a sig- nificant implication in the practice of panda conservation in relation to chemical communication and sexual selection. | LIU DingZhen WEI RongPing ZHANG GuiQuan YUAN Hong WANG ZhiPeng SUN Lixing ZHANG Jianxu ZHANG HeMin | 2008 | Chinese Science Bulletin2008，53，18： | 6 |
| 11 | Uropygial gland volatiles may code for olfactory information about sex,individual,and species in Bengalese finches Lonchura striata显示文摘Over-shadowed by eye-catching vocal and visual signals,chemical communication has long been overlooked in birds.This study aimed at exploring whether volatile composition of the uropygial gland secretion(UGS)of birds was associated with the information about sex,individual and species.By using dichloromethane extraction and gas chromatography-mass spectrometry(GC-MS),we analyzed the UGS volatiles of domesticated Bengalese finches(Lonchura striata,Estrildiea)which is also known as white-rumped munias.We characterized 16 volatile molecules from the UGS,including eight n-alkanols,five diesters,an ester,an aldehyde and a fatty acid,and quantified them in terms of GC peak area percentages(relative abundances).Among these compounds,hexadecanol and octadecanol were major components in both sexes.The former was richer in males than in females and the latter richer in females than in males,suggesting that they might be male and female pheromone candidates,respectively.The high inter-individual variations,in relative abundance,of the UGS volatiles implied that these compounds might carry information about individuality.The similarity between GC profiles of the UGS and wing feather from same individuals indicates that the birds might preen the secretion to their feathers to transmit chemical cues.Additionally,by comparing with three sympatric passerine species,i.e.,zebra finches Taeniopygia guttata,yellow-bowed buntings Emberiza chrysophrys and rooks Corvus frugilegus,we found that the composition of C_ 13-C_ 18 alkanols in the UGS might code for information about species.Our study also showed that quantitative differences(degree)of same UGS volatiles might be the key for the Bengalese finch to code for information about sex and individuality whereas both the kind and degree of UGS constituents could be utilized to code for information about species. | Jian-Xu ZHANG Lixing SUN Ming-Xue ZUO | 2009 | Current Zoology2009，55，5： | 6 |

| 13 | A two-scale second-order moment two-phase turbulence model for simulating dense gas-particle flows显示文摘A two-scale second-order moment two-phase turbulence model accounting for inter-particle collision is developed, based on the concepts of particle large-scale fluctuation due to turbulence and particle small-scale fluctuation due to collision and through a unified treatment of these two kinds of fluctuations. The proposed model is used to simulate gas-particle flows in a channel and in a downer. Simulation results are in agreement with the experimental results reported in references and are near the results obtained using the single-scale second-order moment two-phase turbulence model superposed with a particle collision model (USM-θ model)in most regions. | Zhuoxiong Zeng Lixing Zhou Jian Zhang | 2005 | Acta Mechanica Sinica2005，21，5： | 4 |

| 15 | Geological settings and metallogenesis of high-grade iron deposits in China显示文摘The predominant types of high-grade iron deposits in China include skarn,sedimentary metamorphic(banded ironformation,BIF-type),continental/submarine volcanic-hosted and magmatic Fe-Ti-Voxide deposits.Based on a comprehensive review of current studies on these deposits,this paper suggests that the oxygen concentration in atmosphere played an important role for the formation of BIFs,whereas the tectonic setting and deep magmatic differentiation processes are more important for the other types.Notably,both high temperature and high pressure experiments and melt inclusion studies indicate that during the differentiation,high temperature magmas could develop iron-rich magma via liquid immiscibility but not pure oxide melt('iron ore magma').Fe-P melt could be generated directly by liquid immiscibility under hydrous and oxidized condition.The formation of high-grade iron deposits is mostly associated with the processes related to multiple stages of superimposition,e.g.,desiliconization and iron enrichment,removal of impurity,and remobilization and re-precipitation of iron.According to the temporal evolution,the high-grade iron deposit could be divided into multi-episode superimposition type(temporally discontinuous mineralization)and multi-stage superimposition type(temporally continuous mineralization).The former is represented by the sedimentary metamorphic iron deposit,and the latter includes those related to magmatic-hydrothermal fluids(e.g.,skarn,volcanic-hosted and magmatic types). | Zhaochong ZHANG Houmin LI Jianwei LI Xie-Yan SONG Hao HU Lixing LI Fengmei CHAI Tong HOU Deru XU | 2021 | Science China Earth Sciences2021，64，5： | 4 |
| 16 | Innovations of phosphorus sustainability:implications for the whole chain显示文摘Phosphorus(P)is a non-renewable resource,therefore ensuring global food and environmental security depends upon sustainable P management.To achieve this goal,sustainable P management in the upstream and downstream sectors of agriculture from mineral extraction to food consumption must be addressed systematically.The innovation and feasibility of P sustainability are highlighted from the perspective of the whole P-based chain,including the mining and processing of P rock,production of P fertilizers,soil and rhizosphere processes involving P,absorption and utilization of P by plants,P in livestock production,as well as flow and management of P at the catchment scale.The paper also emphasizes the importance of recycling P and the current challenges of P recovery.Finally,sustainable solutions of holistic P management are proposed from the perspective of technology improvement with policy support. | Jianbo SHEN Liyang WANG Xiaoqiang JIAO Fanlei MENG Lin ZHANG Gu FENG Junling ZHANG Lixing YUAN Lin MA Yong HOU Tao ZHANG Weifeng ZHANG Guohua LI Kai ZHANG Fusuo ZHANG | 2019 | Frontiers of Agricultural Science and Engineering2019，6，4： | 4 |
| 17 | Large-eddy structures of turbulent swirling flows and methane-air swirling diffusion combustion显示文摘Turbulent swirling flows and methane-air swirling diffusion combustion are studied by large-eddy simulation (LES) using a Smagorinsky-Lilly subgrid scale turbulence model and a second-order moment (SOM) SGS combustion model, and also by RANS modeling using the Reynolds Stress equation model with the IPCM+wall and IPCM pressure-strain models and SOM combustion model. The LES statistical results for swirling flows give good agreement with the experimental results, indicating that the adopted subgrid-scale turbulence model is suitable for swirling flows.The LES instantaneous results show the complex vortex shedding pattern in swirling flows. The initially formed large vortex structures soon break up in swirling flows. The LES statistical results of combustion modeling are near the experimental results and are as good as the RANS-SOM modeling results. The LES results show that the size and range of large vortex structures in swirling combustion are different from those of isothermal swirling flows, and the chemical reaction is intensified by the large-eddy vortex structures. | Liyuan Hu Lixing Zhou Jian Zhang | 2005 | Acta Mechanica Sinica2005，21，5： | 4 |
| 18 | Triple Medium Physical Model of Post Fracturing High-Rank Coal Reservoir in Southern Qinshui Basin显示文摘In this paper, influences on the reservoir permeability, the reservoir architecture and the fluid flow pattern caused by hydraulic fracturing are analyzed. Based on the structure and production fluid flow model of post fracturing high-rank coal reservoir, Warren-Root Model is improved. A new physical model that is more suitable for post fracturing high-rank coal reservoir is established. The results show that the width, the flow conductivity and the permeability of hydraulic fractures are much larger than natural fractures in coal bed reservoir. Hydraulic fracture changes the flow pattern of gas and flow channel to wellbore, thus should be treated as an independent medium. Warrant-Root Model has some limitations and can't give a comprehensive interpretation of seepage mechanism in post fracturing high-rank coal reservoir. Modified Warrant-Root Model simplifies coal bed reservoir to an ideal system with hydraulic fracture, orthogonal macroscopic fracture and cuboid matrix. Hydraulic fracture is double wing, vertical and symmetric to wellbore. Coal bed reservoir is divided into cuboids by hydraulic fracture and further by macroscopic fractures. Flow behaviors in coal bed reservoir are simplified to three step flows of gas and two step flows of water. The swap mode of methane between coal matrix and macroscopic fractures is pseudo steady fluid channeling. The flow behaviors of methane to wellbore no longer follow Darcy's Law and are mainly affected by inertia force. The flow pattern of water follows Darcy's Law. The new physical model is more suitable for post fracturing high-rank coal reservoir. | Shiqi Liu Shuxun Sang Qipeng Zhu Jiefang Zhang Hefeng Gao Huihu Liu Lixing Lin | 2015 | Journal of Earth Science2015，26，3： | 3 |
| 19 | RNAi-mediated suppression of the abscisic acid catabolism gene Os ABA8ox1 increases abscisic acid content and tolerance to saline–alkaline stress in rice(Oryza sativa L.)显示文摘Saline–alkaline(SA) stress is characterized by high salinity and high alkalinity(high p H), which severely inhibit plant growth and cause huge losses in crop yields worldwide. Here we show that a moderate elevation of endogenous abscisic acid(ABA) levels by RNAi-mediated suppression of Os ABA8 ox1(Os ABA8 ox1-kd), a key ABA catabolic gene, significantly increased tolerance to SA stress in rice plants. We produced Os ABA8 ox1-kd lines in two different japonica cultivars, Dongdao 4 and Nipponbare. Compared with nontransgenic control plants(WT), the Os ABA8 ox1-kd seedlings accumulated 25.9%–55.7% higher levels of endogenous ABA and exhibited reduced plasmalemma injury, ROS accumulation and Na;/K;ratio, and higher survival rates, under hydroponic alkaline conditions simulated by 10, 15, and 20 mmol L-1 of Na;CO;. In pot trials using SA field soils of different alkali levels(p H 7.59, 8.86, and 9.29), Os ABA8 ox1–kd plants showed markedly higher seedling survival rates and more vigorous plant growth, resulting in significantly higher yield components including panicle number(85.7%–128.6%), spikelets per panicle(36.9%–61.9%), branches(153.9%–236.7%), 1000–kernel weight(20.0%–28.6%), and percentage of filled spikelets(96.6%–1340.8%) at harvest time. Under severe SA soil conditions(p H = 9.29, EC = 834.4 μS cm-1),Os ABA8 ox1-kd lines showed an 194.5%–1090.8% increase in grain yield per plant relative to WT plants.These results suggest that suppression of Os ABA8 ox1 to increase endogenous ABA levels provides a new molecular approach for improving rice yield in SA paddies. | Xiaolong Liu Xianzhi Xie Chongke Zheng Lixing Wei Xiaowei Li Yangyang Jin Guohui Zhang Chang-Jie Jiang Zhengwei Liang | 2022 | The Crop Journal2022，10，2： | 3 |
| 20 | Accurate and precise determination of lead isotope composition in selected geochemical reference materials显示文摘Lead(Pb)isotopes have been extensively employed in tracing sources of Pb and its transport pathways through the environment.However,Pb isotopic ratios in related geochemical reference materials are scarce.Here,we report high-precision Pb isotopic ratios measured by Nu Plasma II MC-ICP-MS using calibrated ^(205)Tl/^(203)Tl=2.38865(NIST SRM 997)for mass discrimination correction.The long-term external precision(2SD)for NISTSRM 981 of Pb,BCR-2,and BHVO-2 are 0.31‰(n=105),0.42‰(n=11),and 0.25‰(n=5)for ^(208)Pb/ ^(206)Pb and 0.16‰,0.53‰,and 0.07‰for ^(206)Pb/ ^(207)Pb,both respectively,and their Pb isotopic ratios are in excellent agreement with the recommended values.Using this method,we report for the first time Pb isotopic compositions in shale SGR-1b(USGS);coal CLB-1(USGS);stream sediments GSD-17,-21,and-23(IGGE);soils GSS-12,-13,-14,-15,and-16(IGGE);plants GSV-1,-2,and-3(IGGE);and human hair GSH-1(IGGE). | Guangliang Wu Jian-Ming Zhu Decan Tan Guilin Han Lixing Zhang Kun Ren | 2017 | Acta Geochimica2017，36，3： | 3 |
