1Interannual variability in soil respiration from terrestrial ecosystems in China and its response to climate change显示文摘Soil respiration is an important process in terrestrial carbon cycle.Concerning terrestrial ecosystems in China, quantifying the spatiotemporal pattern of soil respiration at the regional scale is critical in providing a theoretical basis for evaluating carbon budget.In this study, we used an empirically based, semi-mechanistic model including climate and soil properties to estimate annual soil respiration from terrestrial ecosystems in China from 1970 to 2009.We further analyzed the relationship between interannual variability in soil respiration and climatic factors (air temperature and precipitation).Results indicated that the distribution of annual soil respiration showed clear spatial patterns.The highest and lowest annual soil respiration rates appeared in southeastern China and northwestern China, respectively, which was in accordance with the spatial patterns of mean annual air temperature and annual precipitation.Although the mean annual air temperature in northwestern China was higher than that in some regions of northeastern china, a greater topsoil organic carbon storage in northeastern China might result in the higher annual soil respiration in this region.By contrast, lower temperature, less precipitation and smaller topsoil organic carbon pool incurred the lowest annual soil respiration in northwestern China.Annual soil respiration from terrestrial ecosystems in China varied from 4.58 to 5.19 PgCa-1 between 1970 and 2009.During this time period, on average, annual soil respiration was estimated to be 4.83 PgCa-1 .Annual soil respiration in China accounted for 4.93%-6.01% of the global annual soil CO2 emission.The interannual variability in soil respiration depended on the interannual variability in precipitation and mean air temperature.In order to reduce the uncertainty in estimating annual soil respiration at regional scale, more in situ measurements of soil respiration and relevant factors (e.g.climate, soil and vegetation) should be made simultaneously and historical soil property data sets should also be established.CHEN ShuTao HUANG Yao ZOU JianWen SHI YanShu LU YanYu ZHANG Wen HU ZhengHua 2012Science China Earth Sciences2012,55,12:8
2Enhanced removal of organics by permanganate preoxidation using tannic acid as a model compound-Role of in situ formed manganese dioxide显示文摘The eect of permanganate preoxidation on organic matter removal during the coagulation with aluminum chloride was investigated using tannic acid as a model compound. Results showed that a small amount of KMnO4 (0.75 mg/L) increased the removal eciency of tannic acid up to 20%, as compared to the process of coagulation by aluminum chloride alone. The key factor enhancing the removal eciency of tannic acid in preoxidation process was the in situ formation of a reductant manganese dioxide. The complexation model was used to describe the reaction between MnO2 and tannic acid. Under weak pH condition, tannic acid was dicult to be adsorbed by MnO2 due to the static electrical repulsive forces. The presence of Ca2+ served as a bridge to hold the negative charged MnO2 and tannic acid together, which could be a crucial factor inuencing tannic acid adsorption by in-situ manganese dioxide.ZHANG Lizhu MA Jun LI Xin WANG Shutao 2009Journal of Environmental Sciences2009,21,7:7
32001-2005年中国4省份精神疾病的患病率、治疗情况和相关残疾:一项流行病学调查显示文摘背景在中国和其他中等收入国家,神经精神状况是影响男性和女性健康的最重要的原因,但由于缺乏有关各种精神疾病患病率、治疗情况和相关残疾的高质量的和具有国家特异性的资料,这些国家提高精神卫生服务的工作受到了限制。因此,我们在中国4个省份开展了一系列流行病学研究,以此来估算相关数据。方法采用多阶段分层随机抽样的方法在中国的4个省抽取了96个城市和267个农村作为初级抽样点;1.13亿个年龄≥18岁的成年人的抽样框架涵盖了中国12%的成年人。在抽样点使用简单随机抽样法选取63004例受试者,采用一般健康问卷(GHQ)的扩展版对这些个体进行筛查,并由精神科医生使用中文版的诊断与统计手册(DSM).Iv轴I障碍定式临床检查(SCID)问卷对其中的16577例受试者进行调查。结果所有精神疾病近1个月的校正患病率为17.5%(95%CI16.6%~18.5%)。其中,心境障碍患病率为6.1%(95%CI5.7%~6.6%),焦虑障碍为5.6%(95%cI5.0%~6.3%),物质滥用障碍为5.9%(95%CI5-3%~6.5%),精神病性障碍为1.0%(95%C10.8%~1.1%)。女性的心境障碍和焦虑障碍的患病率比男性高,年龄〉140岁个体的患病率高于年龄〈40岁的个体。男性酒精使用障碍的患病率是女性的48倍。农村居民比城市居民更可能患有抑郁障碍和酒精依赖。在被诊断患有某种精神疾病的人群中,24%存在由所患精神疾病引起的中度或重度残疾,8%曾向专业人员寻求过帮助,5%曾就诊于精神科。结论本研究结果与全球疾病负担分析中使用的中国精神疾病的患病率、残疾和治疗率估计值有相当大的差距,这需要引起中、低收入国家注意,在提高精神卫生服务前需针对国家具体情况进行详细的现状分析。Jingxuan Zhang Qichang Shi Zhiqiang Song Zhijie Ding Shutao Pang Xianyun Li Yali Zhang Zhiqing Wang 张亚利(译) 安静(审校) 费立鹏(审校) 2009世界临床医学2009,,11:5

5Nonswellable hydrogels with robust micro/nano-structures and durable superoleophobic surfaces under seawater显示文摘Hydrogels, composed mainly of water trapped in three dimensional cross-linked polymer networks, have been widely utilized to construct underwater superoleophobic surfaces. However, the swelling nature and instability of hydrogels under complex marine environment will weaken their underwater superoleophobicity. Herein, we synthesize structured poly(2-hydroxyethylmethacrylate)(PHEMA) hydrogels by using sandpaper as templates. The robust non-swelling of PHEMA hydrogel ensures that micro/nano-structures on the surface of PHEMA hydrogels can be well maintained. Moreover, when roughness Ra of about 3~4 μm, the surface has superior oil-repellency. Additionally, even after immersing in seawater for one-month, their breaking strength and toughness can be well kept. The non-swellable hydrogels with long-term stable under seawater superoleophobicity will promote the development of robust superoleophobic materials in marine antifouling coatings,biomedical devices and oil/water separation.Ling Lin Hui Yi Xinglin Guo Pengchao Zhang Lie Chen Dezhao Hao Shutao Wang Mingjie Liu Lei Jiang 2018Science China Chemistry2018,61,1:3
6Oil-soluble Ni-Mo sulfide nanoparticles and their hydrogenation catalytic properties显示文摘Oil-soluble bimetallic Ni-Mo sulfide nanoparticles(NiMoS) with narrow size distribution were successfully synthesized through a composite-surfactants-assisted-solvothermal process.The surface functionality and lipophilicity of the Ni-Mo sulfides were shown by transmission electronic microscopy,Fourier transform infrared and ultraviolet spectroscopy.The as-prepared Ni-Mo sulfides supported on activated carbon(NiMoS/AC) exhibited enhanced catalytic activity towards naphthalene hydrogenation instead of cracking.For comparison,CoMoS/AC and MoS2/AC catalysts were also prepared through similar procedures,and it was found that their catalytic performance decreased in the order of NiMoS/AC>CoMoS/AC>MoS2/AC.Furthermore,the activity of the bimetallic NiMoS nanocatalyst can be effectively tuned via variation of the atomic ratio of Ni/(Ni+Mo).Liu Chenguang Wang Shutao An Changhua Yan Fang He Jie Wang Zongxian Zhang Qin-Hui 2013Petroleum Science2013,10,4:2

10Mechanical design of a cryogenic Delta-Knot undulator for high energy photon source显示文摘Introduction A novel type of pure permanent cryogenic Delta–Knot Undulator was developed at IHEP to supply a high flux of full adjustable polarization synchrotron radiation with low on-axis power density.This prototype was an active attempt and early exploration for future APPLE–Knot undulator,which will be used at high energy photon source(HEPS).Materials and methods There are several challenges to develop a cryogenic delta undulator,such as the complicated structure,the influence of large magnetic force,and the magnetic measurement difficulty due to the very small gap.In this paper,the mechanical design for overcoming these difficulties will be presented in detail.Conclusion A special hall measuring system is developed,and the preliminary results agree with the theoretical results.This undulator prototype will provide valuable experience for angle magnetization technology,intricate magnetic attraction structure design,and magnetic field measurement under closed small space.Shuchen Sun Huihua Lu Xiaoyu Li Xiangzhen Zhang Yanwei Yang Yajun Sun Lei Zhang Yuhui Li Zhiqiang Li Wan Chen Lingling Gong Shutao Zhao Qing Guo Keyun Gong Yongsheng Huang Yufeng Yang 2021Radiation Detection Technology and Methods2021,5,1:1

14Propagation properties of foreshock cavitons: Cluster observations显示文摘Foreshock cavitons are transient phenomena observed in the terrestrial foreshock region.They are characterized by a simultaneous depression of magnetic field magnitude and plasma density,which are bounded with enhancements of these two parameters and surrounded by ultralow frequency(ULF)waves.Previous studies focused on the interplanetary magnetic field(IMF)conditions,solar wind(SW)conditions,and the growth of the foreshock waves related to the generation of foreshock cavitons.Previously,a multipoint spacecraft analysis method using Cluster data was applied to analyze only two foreshock cavitons,and this method did not consider uncertainties.In this study,multipoint spacecraft analysis methods,including the timing method,the minimum directional derivative(MDD)method,and the spatiotemporal difference(STD)method are applied to determine the velocity in both spacecraft and solar wind frames.The propagation properties show good agreement with previous results from simulations and observations that most cavitons move sunward in the solar wind frame,with the velocities larger than the Alfvén speed.The propagation properties of foreshock cavitons support the formation mechanism of cavitons in previous simulations,which suggested that cavitons are formed due to the nonlinear evolution of compressive ULF waves.We find that there is clear decreasing trend between the size of cavitons and their velocity in the solar wind frame.In addition,the timing method considering errors has been applied to study the evolution properties by comparing the velocities with errors of the leading and trailing edges,and we identify three stable cavitons and one contracting caviton,which has not been studied before.Most cavitons should remain stable when they travel toward the Earth’s bow shock.The relationship between the size of foreshock cavitons and their distance from the bow shock is also discussed.WANG MengMeng YAO ShuTao SHI QuanQi ZHANG Hui TIAN AnMin DEGELING Alexander William ZHANG Shuai GUO RuiLong SUN WeiJie LIU Ji BAI ShiChen SHEN XiaoChen ZHU XiaoQiong FU SuiYan PU ZuYin 2020Science China(Technological Sciences)2020,63,1:1

20Insight into the Dual Cycle Mechanism of Methanol-to-OIefins Reaction over SAPO-34 Molecular Sieve by Isotopic Tracer Studies显示文摘Methanol-to-olefins(MTO)reaction is one of the important non-petroleum routes to produce light olefinsover acidic molecular sieves.In this study,the complete reaction course of MTO on SAPO-34 molecular sieve with retained organics evolution from induction period to deactivation period was investigated systematically at different weight hourly space velocities(WHSV)of methanol.By the aid of 12C/3C-methanol isotopic switch experiment,the dual cycle mechanism involving aromatics-based cycle and alkenes-based cycle was evaluated during the whole reac-tion process.The detailed reaction route varied with the evolution of the retained organics in the catalyst at different reaction stages.The aromatics-based cycle and alkenes-based cycle alternately dominate the reaction process.In the efficient reaction period,aromatics-based cvcle is the main reaction mechanism,while in the induction and deactiva-tion periods.the contribution of alkenes-based cvcle mechanism will become more important.YU Bowen LOU Caiyi ZHANG Wenna XU Shutao HAN Jingfeng YU Zhengxi WEI Yingxu LIU Zhongmin 2020Chemical Research in Chinese Universities2020,36,6:1
