The Fuchuan ophiolite is located in the northeasternmost segment of the Neoproterozoic Jiangnan orogen and consists mainly of harzburgites,with minor dunites,pyroxenite and gabbro veins and dykes.In order to investigate the genesis and tectonic setting of the Fuchuan ophiolite and chromitites,in situ analyses of unaltered chromites and silicates were carried out.Trace element analyses of unaltered chromites from the Fuchuan chromitites indicate the parental magma is of mid-ocean ridge basalt(MORB)-like origin,with the Ti/Fe^(3+#)–Ga/Fe^(3+#)diagram of chromites showing that the chromitites are a result of melt/rock interaction of MORB melts with mantle peridotites,and that the Fuchuan harzburgites present the dual features of MORB and supra-subduction zone peridotites(SSZP).Trace and rare earth element(REE)analyses of olivines and orthopyroxenes from the Fuchuan harzburgites hint at the possibility of mantle metasomatism influenced by SSZ-subducted fluids.Finally,integrating with previous study,the Fuchuan ophiolite and chromitites might have been formed in a back-arc spreading ridge between the Yangtze and Cathaysia blocks during the Neoproterozoic.

Indium tin oxide films,an important n-type semiconductor oxide,show great prospects in optoelectronic device applications.Consequently,as a key raw material of targets for sputtering films,it is important to prepare low-resistivity indium tin oxide powders.Herein,low-resistivity indium tin oxide submicro-cubes are synthesized by a seed-assisted coprecipitation method.The effects of seed content,In^(3+)concentration,aging time,reaction temperature and calcination temperature on resistivity were investigated by single factor and orthogonal experiments.To ensure reliability and reproducibility of data,each experiment was repeated three times and resistivity of each sample was measured three times to obtain average value.The results indicated that optimal sample was matched with cubic phase In_(2)O_(3).The single-crystal indium tin oxide particles exhibited a regular cubic shape with a size of nearly 500 nm and low resistivity of 0.814Ω·cm.Compared with particles prepared by the conventional coprecipitation method,indium tin oxide submicro-cubes showed good dispersion.The presence of seed particles provided nucleation sites with lower energy barriers and promoted formation of submicro-cubes.The face-to-face contact among particles and good dispersion contributed to electron transfer,resulting in lower resistivity.The seed-assisted synthesis provides a novel way to prepare low-resistivity indium tin oxide submicro-cubes.

文章主要以天山北坡经济带为研究对象,基于新疆天山北坡经济带内25个县(市)的人口数据与GDP,运用区域重心模型、地理集中度的方法,分析了天山北坡经济带人口与经济空间耦合与协调发展程度,并采用耦合指数对天山北坡经济带人口与经济发展空间耦合类型进行等级划分。研究结果显示,人口重心变动与经济重心变动方向基本一致,即在整体上存在耦合关系,人口地理集中度与经济地理集中度高度相关。结合耦合指数,天山北坡经济带可划分为人口集聚超前于经济集聚、人口集聚滞后于经济集聚、人口集聚与经济集聚相协调三类区域。

For Decombel Danny Camiel, Xinjiang is not only a place of opportunity where he started his agricultural career, but also his home away from home.“It was a good decision to set up a business in Xinjiang. I don’t think any place other than Xinjiang could have given me such an opportunity,”said Decombel Danny Camiel, a 59-year-old Belgian who runs a fertilizer company and breeds cattle in northwest China.
