| 1 | 土壤、农作物中及家畜体内的微量营养元素(英文)显示文摘微量营养元素通常富集在表层土壤中,其含量随土层深度递减。尽管土壤中大多数微量元素的含量很高,但只有一小部分能被植物吸收。微量营养元素,也被称为痕迹元素,所需数量微小,但其缺乏会对农作物生产和动物健康造成严重影响。农作物对不同微量营养元素有着不同的反应。芸苔和豆类对Mo和B有较高的响应度,而玉米和其他谷类对Zn和Cu较为敏感。在温润和湿热地区,由于强降雨和强淋溶作用,微量营养元素缺乏较为普遍。土壤pH值是影响微量营养元素对植物有效性的重要因素之一。除Mo以外,微量营养元素的有效性随pH的增加而减小,Mo的有效性随pH的增加而增加。对于大多数植物来说,叶片中的微量营养元素含量高于植物的其他部分。因此,可以用叶片作为样品来测定农作物中微量营养元素的含量。大多数微量营养元素缺乏表现在植物顶部的新叶上,而过量则表现在老叶上。根据Deckers和Steinnes的结论,土壤较为贫瘠的发展中国家与土壤肥沃的欧洲及北美地区相比,微量营养元素缺乏现象较为普遍。许多营养元素缺乏区位于潮湿的热带地区,土壤极度贫瘠、高度风化和/或强淋溶,营养元素十分匮乏。此类其他土壤分部于半干旱及毗邻地区,这些地区的碱性和石灰性土壤条件严重限制了微量营养素对植物的供给。通常,可以满足草料作物生长的Cu、Fe、Mn、Zn、Se含量水平,却不能满足家畜的需要。Se是植物生长所不需要的微量元素,因此草料作物中Se的含量很少。然而,如果动物所食农作物和草料中Se含量偏低,会造成严重的肌肉异常和其他疾病。白肌病是最常见的由于Se缺乏造成的疾病,在牛犊和羔羊中都有发现。本文讨论了与动物需求相关的农作物微量营养元素充足度。 | Umesh C.

| 2 | 七个发达国家卫生系统的领导与治理显示文摘本文运用结构式调查方法,探讨了澳大利亚、英国、德国、荷兰、挪威、瑞典和瑞士七个发达国家卫生系统的领导和治理情况。领导与治理模式包含三项基本职能:优先顺序设置、绩效监管和问责制。各国卫生系统的领导和治理方法存在着显著差异,零散并略显随意。虽然各国在卫生系统的总体目标上达成了共识,但设置优先顺序的途径各不相同。成本效益分析作为设置卫生系统运行优先顺序的一个主要方法被各国加以广泛运用,但并未发挥核心作用。各国虽然处于不同的发展阶段,但绩效监管却能广泛吸收有益意见。问责制特别是在最优方法的不确定性方面,各国之间的差异最大。大多数情况下,市场机制、选举程序、直接经济激励以及专业监督与控制等几种不同问责机制的组合可能更为合适。而且这些机制应与优先顺序设置和绩效监管协调一致。 | Peter C Smith Anders Anell Reinhard Busse Luca Crivelli Judith Healy Anne Karin Lindahl Gert Westert Tobechukwu Kene | 2012 | 中国卫生政策研究2012，5，11： | 13 |
| 3 | Arrangement of High-standard Basic Farmland Construction Based on Village-region Cultivated Land Quality Uniformity显示文摘As an important constitute of land consolidation, high-standard basic farmland construction is an important means to protect the quantity, quality and ecological environment of cultivated land. Its target not only lies in the increase of cultivated land quantity, but also the improvement of cultivated land quality, agricultural production conditions and ecosystem environments. In the present study, the quality evaluation method and construction arrangement of cultivated land were explored to facilitate the process of decision-making and implementation for high-standard basic farmland construction(HSBFC) with administrative village as the unit. Taking the land comprehensive improvement project area in Quzhou County, Handan City, Hebei Province as a case study, the whole process of the study comprised of three steps: 1) establishment of the evaluation model of cultivated land quality uniformity based on regional optimum cultivated land quality, and construction of the uniformity evaluation index system from the aspects of soil fertility quality, engineering quality, spatial quality and eco-environment quality, according to the new concept of cultivated land quality; 2) calculation of cultivated land quality uniformity by grading indicators, assigning scores and weighting sums, exploring the local homogenization characteristics of regional cultivated land quality through spatial autocorrelation analysis, and analyzing the constraints and transformative potential of barrier factors; 3) arrangement of HSBFC according to the principle of concentration, continuity and priority to the easy operation. The results revealed that the value of farmland quality uniformity for the administrative villages in the study area was between 7.76 and 21.96, and there was a difference between various administrative villages. The regional spatial autocorrelation patterns included High-High(HH), Low-Low(LL), High-Low(HL) and Low-High(LH). These indicate that regional cultivated land quality has local homogenization characteristics. The most restrictive factors in the study area were the medium and low transformation difficulty indexes, including soil organic matter content, farmland shelterbelt network density, field regularity and scale of the field. In addition, there were also high transformation difficulty indicators in some areas, such as sectional configuration. The project area was divided into four partitions: major construction area, secondary construction area, general construction area, and conditional construction area. The cultivated land area of each subarea was 1538.85 ha, 1224.27 ha, 555.93 ha, and 1666.63 ha, respectively. This comprised of 30.87%, 24.56%, 11.15% and 33.42% of the total project area, respectively. The evaluation model and index system could satisfy the evaluation of farmland quality and diagnosis of obstacle factors to facilitate the subsequent construction decision. The present study provides reference for the practice of regional HSBFC, and a new feasible idea and method for related studies. | SONG Wen WU Kening ZHAO Huafu ZHAO Rui LI Ting | 2019 | Chinese Geographical Science2019，29，2： | 12 |
| 4 | Progress and challenges of carbon-fueled solid oxide fuel cells anode显示文摘Carbon-fueled solid oxide fuel cells(CF-SOFCs)can electrochemically convert the chemical energy in carbon into electricity,which demonstrate both superior electrical efficiency and fuel utilisation compared to all other types of fuel cells.However,using solid carbon as the fuel of SOFCs also faces some challenges,the fluid mobility and reactive activity of carbon-based fuels are much lower than those of gaseous fuels.Therefore,the anode reaction kinetics plays a crucial role in determining the electrochemical performance of CF-SOFCs.Herein,the progress of various anodes in CF-SOFCs is reviewed from the perspective of material compositions,electrochemical performance and microstructures.Challenges faced in developing high performance anodes for CF-SOFCs are also discussed. | Minjian Ma Xiaoxia Yang Jinshuo Qiao Wang Sun Zhenhua Wang Kening Sun | 2021 | Journal of Energy Chemistry2021，30，5： | 8 |
| 5 | Catalytic performance of hierarchical H-ZSM-5/MCM-41 for methanol dehydration to dimethyl ether显示文摘Micro-mesoporous composite molecular sieves H-ZSM-5/MCM-41 were prepared by the hydrothermal technique with alkali-treated H-ZSM-5zeolite as the source and characterized by scanning electron microscopy,transmission electron microscopy,energy dispersive spectroscopy,X-ray diffraction,N2 adsorption-desorption measurement and NH3 temperature-programmed desorption.The catalytic performances for the methanol dehydration to dimethyl ether over H-ZSM-5/MCM-41 were evaluated.Among these catalysts,H-ZSM-5/MCM-41 prepared with NaOH dosage (nNa/nSi) varying from 0.4 to 0.47 presented excellent catalytic activity with more than 80%methanol conversion and 100%dimethyl ether selectivity in a wide temperature range of 170—300℃,and H-ZSM-5/MCM-41 prepared with nNa/nSi=0.47 showed constant methanol conversion of about 88.7%,100% dimethyl ether selectivity and excellent lifetime at 220℃.The excellent catalytic performances were due to the highly active and uniform acidic sites and the hierarchical porosity in the micro-mesoporous composite molecular sieves.The catalytic mechanism of H-ZSM-5/MCM-41 for the methanol dehydration to dimethyl ether process was also discussed. | Yu Sang Hongxiao Liu Shichao He Hansheng Li Qingze Jiao Qin Wu Kening Sun | 2013 | Journal of Energy Chemistry2013，22，5： | 7 |
| 6 | Effects of Nitrogen Application on Plant Growth and Soil Inorganic Nitrogen Content in Alpine Grasslands显示文摘In order to further determine the nitrogen demand of plants in alpine grassland ecosystem,different nitrogen levels( 0,1,2,4,8,16,24,32 g/m2)were designed through field control to study the responses of different plant functional groups( grass,sedge and weed) to different nitrogen application levels in the aboveground biomass and soil inorganic nitrogen( nitrate nitrogen and ammonium nitrogen).The results showed that with the increase of nitrogen application rate,the aboveground biomass of different functional groups increased linearly,and the soil inorganic nitrogen content increased with the increase of nitrogen application rate,among which treatments N16,N24 and N32 increased significantly in soil nitrate nitrogen content( P < 0.05).The results showed that the optimal nitrogen content in alpine grasslands was 8 g/m^2,which could not only promote plant growth,but also effectively control soil nitrate nitrogen content. | Bing YU Kening WU | 2018 | Agricultural Biotechnology2018，7，6： | 4 |
| 7 | Leaching Effect of Organic Acids on Heavy Metal Contaminated Soil显示文摘With the contamination of soil heavy metals becoming more and more serious,remediation has become a hot issue,and it is of great significance to study the remediation effects of heavy metal contaminated soil. The heavy metal contaminated soil was leached with water,acetic acid and citric acid,and the pH value of the soil after leaching was adjusted with 2% lime water. Finally,the pH value and conductivity of the soil leacheate were determined. The results showed that the best leacheate was citric acid for the remediation of soil contaminated with heavy metals Cu,Cd and Pb,and the optimum leaching concentration was 1. 0,0. 4,0. 7 mol/L,respectively. For the remediation of soil contaminated with Zn,the best leacheate was acetic acid,and the optimal leaching concentration was 1 mol/L. The leaching effect of lime water on heavy metal contaminated soil was positively correlated with the concentration of organic acid,that is,the leaching effect on heavy metals was better at stronger acidic condition. The conductivity of the soil sample treated with lime water increased with the increase of the concentration of organic acid,and at the same concentration,the conductivity was in the order of citric acid > acetic acid. | Bing YU Mingxin MEN Peijia LIU Kening WU | 2019 | Agricultural Biotechnology2019，8，1： | 3 |
| 8 | Characterization of Some Calcareous Soils from Henan and Their Proposed Classification in Chinese Soil Taxonomy显示文摘Calcareous soils are those soils containing layers of carbonate accumulation formed by either secondary accumulation or inheritance of CaCO_3 from calcareous parent materials.These soils are widely distributed in arid,semi-arid and even some humid climate environments.However,in the Chinese Soil Taxonomy(CST,3rd version),the soils that contain large amounts of CaCO_3 but do not meet requirements of Aridosols are classified as Hapli-Ustic Cambosols.This group also includes many non-calcareous soils and those soils strongly affected by secondary carbonate accumulation together with quite dissimilar soils in terms of their morphology and properties.This study was conducted to determine calcification patterns and calcic processes occurring in representative pedons of calcareous soils in northwestern Henan Province,China and to classify these soils in CST.A Calcic subgroup was proposed to add within the Hapli-Ustic Cambosols.A diagnostic key was also provided to separate this subgroup from the Typic subgroup.In this way the different calcification degrees of soils were better reflected in the classification,which should lead to more uniform interpretive groups for better soil management. | JU Bing WU Kening ZHANG Ganlin David G.

| 9 | A classification scheme for Earth’s critical zones and its application in China显示文摘As the thin layer at the Earth’s terrestrial surface,the critical zone(CZ)ranges from the vegetation canopy to the aquifer or the interface between saprolite and bedrock and varies greatly in space.In the last decade,much attention has been paid to the establishment of Critical Zone Observatories(CZOs)that focus on various aspects of CZ science over different time scales.However,to the best of our knowledge,few studies have explicitly contributed to CZ classification or regionalization;thus,the spatial patterns of similar CZs have not been clearly identified.This study proposed a three-category CZ classification scheme by integrating environmental factors that greatly affect the transfer of energy and mass in the Earth’s near-surface environment and thus dominate CZ formation and evolution,i.e.,climate,parent material,soil type,groundwater table depth,geomorphology and land use.The main goal was to highlight the zonality of these driving forces,of which the high-category classification units were overlaid to delineate the CZ boundaries.The CZ regionalization of China was performed as a case study,resulting in 44 major regions(1st category),100 submajor regions(2nd category)and 1448 regions(3rd category).The spatial distributions and driving factors of the ten largest regions were identified,followed by a simple comparison of the CZO network.Then,the proposed CZ regionalization was compared with recent studies on regionalization in China to evaluate its successes and weaknesses.By linking together CZ studies from the last decade,we advocate that a theoretical framework integrating the CZ evolution processes with ecological functions acts as one of the frontiers of CZ science.Our study demonstrates that the proposed three-category CZ classification scheme effectively identifies the spatial variations in CZs and could thus be further applied in other areas to advance terrestrial environmental research and provide decision support for the sustainable management of natural resources. | Ganlin ZHANG Xiaodong SONG Kening WU | 2021 | Science China Earth Sciences2021，64，10： | 3 |

| 11 | Balancing particle properties for practical lithium-ion batteries显示文摘As a state-of-the-art secondary battery,lithium-ion batteries(LIBs)have dominated the consumer electronics market since Sony unveiled the commercial secondary battery with LiCoO_(2) as the negative electrode material in the early 1990s.The key to the efficient operation of LIBs lies in the effective contact between the Li-ion-rich electrolyte and the active material particles in the electrode.The particle properties of the electrode materials affect the lithium ion diffusion path,diffusion resistance,contact area with the active material,the electrochemical performance and the energy density of batteries.To achieve satisfied comprehensive performance and of LIBs,it is not only necessary to focus on the modification of materials,but also to balance the properties of electrode material particles.Therefore,in this review,we analyze the influence of particle properties on the battery performance from three perspectives:particle size,particle size distribution,and particle shape.A deep understanding of the effect and mechanism of particles on electrodes and batteries will help develop and manufacture practical LIBs. | Jing Zhang Jinshuo Qiao Kening Sun Zhenhua Wang | 2022 | Particuology2022，20，2： | 2 |
| 12 | Synthesis of La_(0.9)Sr_(0.1)Ga_(0.8)Mg_(0.2)O_(3-δ) Powder for Solid Oxide Fuel Cell by a Nitrate-Citrate Combustion Route显示文摘A nitrate-citrate combustion route to synthesize La0.9Sr0.1 Ga0.8 Mg0.2O3-δ powder for solid oxide fuel cell application was presented. This route is based on the gelling of nitrate solutions by the addition of citric acid and ammonium hydroxide, followed by an intense combustion process due to an exothermic redox reaction between nitrate and citrate ions. The optimum technical parameters are that the pH value is 5, and the molar ratio of citric acid to the total metallic ion is 1.5:1. X-ray diffraction characterization of calcined gel shows that pure phase was synthesized after calcination at 1400℃ for 10 h, and the TEM result shows the calcined powder with average particle size is about 150 nm. The grain resistance contributes to the total resistance of sintered pellet below 500℃. The conductivity of the sintered pellent at 800℃ was 0.07 S-1.cm-1 higher than the conductivity of YSZ(0.05S-1.cm-1 at 800℃) | Naiqing ZHANG, Kening SUN, Derui ZHOU and Ningning WUHarbin Institute of Technology, Harbin 150001, China | 2004 | Journal of Materials Science & Technology2004，20，6： | 2 |

| 14 | GPCR activation:protonation and membrane potential显示文摘GPCR proteins represent the largest family of signaling membrane proteins in eukaryotic cells.Their importance to basic cell biology,human diseases,and pharma-ceutical interventions is well established.Many crystal structures of GPCR proteins have been reported in both active and inactive conformations.These data indicate that agonist binding alone is not suffi cient to trigger the conformational change of GPCRs necessary for binding of downstream G-proteins,yet other essential factors re-main elusive.Based on analysis of available GPCR crystal structures,we identifi ed a potential conformational switch around the conserved Asp2.50,which consistently shows distinct conformations between inactive and active states.Combining the structural information with the current literature,we propose an energy-coupling mechanism,in which the interaction between a charge change of the GPCR protein and the membrane potential of the living cell plays a key role for GPCR activation. | Xuejun C.Zhang Kening Sun Laixing Zhang Xuemei Li Can Cao | 2013 | Protein & Cell2013，4，10： | 1 |
