| 1 | 黄河上游盆地重组所导致的快速侵蚀下切显示文摘高起伏的造山高原边缘的快速剥蚀常被用来指代区域地表隆升^(1~3)。然而,诸如岩体隆升的空间差异~4,降雨的地形效应以及冰川~5、滑坡导致的河道堵塞^(6,7)等阻碍河流下切的因素,可能会使剥蚀作用严重滞后于地表抬升~8。本文中,我们通过研究青藏高原东北缘黄河沿岸沉积盆地的地层学、年代学和地貌学特征,重建黄河上游侵蚀下切的时间、速率以及模式。我们发现河流下切的起始时间明显晚于山体开始隆升的时间(14~8Ma)~9。高原边缘的河流下切始于1.8Ma^(10),然后以大约350km/Ma的速度向上游传递^(11)。我们认为该地区在气候驱动下的湖泊扩张并溢出作用是黄河上游快速下切的主要原因,并最终导致了现代黄河地貌的形成。 | W.H.Craddock E.Kirby N.W.Harkins H.P.Zhang X.H.Shi J.H.Liu 贾伟(译) 张波(译) 苏琦(校) | 2019 | 世界地震译丛2019，50，4： | 0 |
| 2 | Separators for Lithium Ion Batteries显示文摘1 Results A separator for rechargeable batteries is a microporous membrane placed between electrodes of opposite polarity, keeping them apart to prevent electrical short circuits and at the same time allowing rapid transport of lithium ions that are needed to complete the circuit during the passage of current in an electrochemical cell, and thus plays a key role in determining the performance of the lithium ion battery. Here provides a comprehensive overview of various types of separators for lithium io... | G.C.Li H.P.Zhang Y.P.Wu | 2007 | 复旦学报(自然科学版)2007，46，5： | 0 |
| 3 | A Novel Micro-porous Polymer Electrolyte Comprising SnO_2 Nanorods and P(MMA-AN)显示文摘1 Results Micro-porous polymer electrolytes(MPEs), which almost obtained by the conventional methods of phase inversion process or immersion precipitation method, have significant advantages such as high ionic conductivity and excellent mechanical properties[1].In our work, micro-porous structure is obtained by adding SnO2 nanorods usually used as gas senor materials into the polymer matrix, which proves a new way to prepare MPEs.SnO2 nanorods were synthesized by microemulsion hydrothermal method[2].
