Advanced Energy Materials, EarlyView.This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

, 2008 径流曲线法计算过程简单，所需的资料易于获取，尤其适用于资料缺乏的地区。本文针对黄土高原的降雨径流、土壤、气候特点，对径流曲线法进行了改进，并提出了一个简化、适应黄土区坡面和流域的降水产流模型，研究结果可为该区水资源高效利用、水土流失预报和治理提供重要帮助。主要结论如下：（1）运用黄土高原地区实测降水产流资料对标准SCS-CN模型进行了检验，发现标准CN方法对该区降水产流的预报效率偏低（E=0.294）；经对参数初损率λ重新优化，模型预报精度虽有所提高，但预报效率仍只有0.541 ...

Universal Oxychlorination Strategy in Halide Solid Electrolytes for All‐Solid‐State Batteries
Advanced Energy Materials, EarlyView.A WO2Cl2‐driven oxychlorination strategy enables bulk oxygen incorporation into close‐packed LixMCl6 (M = Zr, Y, Er, In) halide lattices. Oxygen is selectively anchored by W6+ as lattice‐integrated [WO2Cl4]2− units, regulating the anionic framework, diversifying Li coordination, and weakening Li–Cl interactions.

, 2011 【目的】初损率是SCS-CN方法进行流域地表径流预报的基础输入参数之一,影响着径流模拟精度。论文通过研究确定黄土丘陵沟壑区典型小流域初损率取值,为SCS-CN方法在该地区的适用性评价提供参考。【方法】SCS-CN方法中,初损率定义为初损量(Ia)与流域最大蓄水能力(S)的比值,通常取标准值0.2。然而,已有研究表明不同区域初损率取值存在差异。论文选取黄土丘陵沟壑区桥子西沟小流域1987—2006年14场典型降雨事件,采用反算法(BC)和事件分析法(EA)确定流域初损率。【结果】结果表明 ...
