Due to the intrinsic advantages of nontoxicity, low-cost, and abundant resource of metallic zinc, aqueous zinc-ion batteries (ZIBs) have attracted universal interest [1,2]. Tremendous cathode materials have been exploited in aqueous ZIBs, such as manganese-based materials [3-11], Co-based materials [12,13] and vanadium-based materials [14-21].

Co-seismic displacements of the 2011 Mw9.0 Japan earthquake recorded by GPS stations in China and surrounding areas showed a movement toward the epicenter. The horizontal displacements were up to 1 - 3 cm in northeastern China, 3 -8 mm in the North China, and 2 cm in the Korean peninsula. The vertical movements in China were small uplifts.

Journal of Wuhan University of Technology(Materials Science) 2009年第4期24卷 581-587页

作者：张凌燕魏婷婷 College of Resource and Environment Engineering Wuhan University of Technology

The mechanical and thermal properties of polypropylene （PP）/muscovite/ low-density polyethylene （LDPE）/ polypropylenegraftmaleic anhydride （PP-g-MAH） ternary composites were investigated. In PP matrix, muscovite, LDPE, and PP-g-MAH were added as strengthening agent, toughening agent, and compatibilizer, respectively. The effects of dosages of the added materials were analyzed. The - experimental results show that the optimum recipe of PP/muscovite/LDPE/PP-g-MAH composites is 100/10/6/20 （mass ratio）. Compared with the pure PP, the mechanical properties of PP/muscovite/LDPE/PP-g-MAH composites, including notched impact strength, Rockwell hardness and flexural strength, are improved. Although tensile strength is slightly decreased, they have better toughness. Filled with muscovite, the heat-resistance and heat-decompostion of the composites are improved.

[目的]探究黄河流域农业用水绿色效率水平及其演变特征，有助于推进黄河流域农业用水高质量发展。[方法]文章利用超效率EBM模型测算黄河流域9省区农业用水绿色效率，采用KDE及ArcGIS图示法探究效率的区异性及动态演进特征，借助地理探测器考察时空演进的内源性、外源性驱动因素。[结果]（1）从总体变化趋势看，2010—2019年黄河流域农业用水绿色效率平均值在0.95～1.10，呈“降—升—降—升”的“W”型波动上升特征，2011年和2015年为低点；（2）从流域动态演进看，全流域存在“优者更优”现象，中下游地区两极分化明显，农业用水绿色效率提升幅度从上游到中下游递增；（3）从省域异质性看，农业用水绿色效率呈现“北低南高”的空间分布格局，效率值由上游向中下游递增，高效率省份数量在增多；（4）外源性因素是黄河流域农业用水绿色效率的主要驱动力，滴灌面积占比、经济发展水平、每千公顷施用化肥折纯量是控制性因子。[结论]针对黄河流域农业用水绿色效率驱动因素采取差异化措施，实现农业用水效率高质量发展。
