Dianci bileiqi, 2023 针对目前风力发电机叶尖附近空间电荷的分布特性不明确等问题，笔者利用仿真建模手段对风机叶片处于不同旋转角度时叶尖电晕放电进行了仿真研究，将风机叶片旋转时叶尖与周围空气的相对运动等效为叶尖流过的高速气流，考虑正极性离子与其他离子的附着与碰撞作用，建立了一种二维正极性电晕放电空间电荷分布模型；基于上述模型，得到了风机叶片旋转到不同角度时叶尖电晕放电正极性空间电荷的分布特性和以及正离子迁移规律。研究发现，在雷云电场作用下，由于风机叶片旋转时叶尖流过的高速气流提供给空间电荷的迁移速度远大于电场牵引力提供的迁移速度，

SiC对粉碎烧结法制备P型Bi0.5Sb1.5Te3合金热电性能的影响
Fenmo yejin jishu, 2022 向粉碎法制备的Bi0.5Sb1.5Te3+5%Te（质量分数）合金粉体中混入不同体积分数的SiC颗粒，利用放电等离子体烧结法制备SiC复合块体材料，探究块体材料组织和热电性能的变化规律。研究发现：随着SiC体积分数的增加，块体材料的取向性弱化，组织细化，载流子浓度增加，迁移率降低；由于取向性弱化及组织细化，加强了声子散射，降低了晶格热导率。由于SiC复合块体材料的电学性能恶化，块体材料的无量纲热电优值（ZT）并未获得显著的提升；当SiC体积分数为0.40%时，SiC复合块体材料在322 ...

Synthesis and Performance of Functional Ceramic-coated Separator for Lithium-ion Battery [PDF]
, 2015 锂离子电池被广泛用于便携设备领域，也被认为是最具有应用前景的电动汽车动力电池体系。但其现有体系的工作模式（尤其是作为电动汽车的动力电源时）在技术上仍然存在巨大的安全隐患。隔膜是锂离子电池中防止正负极材料直接接触而造成短路的隔板，是保障锂离子电池安全的一大关键因素。目前，商品化的液态锂离子电池大多选用微孔聚烯烃膜作为隔膜，它虽具有适宜的孔径、稳定的化学性能、足够的机械强度等优点，但由于在高温下尺寸稳定性差，容易收缩甚至熔化破膜，造成电池内部短路，可能导致电池发生热失控进而起火爆炸 ...
