Dianci bileiqi, 2016 为找出某500 k V变电站地网腐蚀断裂原因,通过X射线物相分析了地网腐蚀产物和降阻剂成分,对变电站地网周围土壤和降阻剂进行了理化分析和腐蚀电化学试验。分析试验结果得出,地网腐蚀的主要原因是降阻剂腐蚀和硫酸盐还原菌腐蚀。针对腐蚀原因提出了改造措施:更换被腐蚀地网同时清除地网周围降阻剂,在较易发生腐蚀的集中接地装置周围及新换地网与旧地网连接处施加环保高效膨润土防腐剂。

Dianci bileiqi, 2006 接地装置的腐蚀极大地影响了系统的安全运行,形成了接地隐患,严重时将造成事故。分析了接地装置的腐蚀机理、腐蚀环境及腐蚀原因,认为电化学腐蚀是导致接地装置腐蚀的主要原因。电化学腐蚀主要与电解质溶液中的H+和O2的浓度有关,电解质溶液中的H+和O2的浓度越大,电化学腐蚀速度就越快。论述了防止接地装置腐蚀的主要措施——高效膨润土降阻防腐剂法和阴极保护法的应用情况;在工程中,将高效膨润土降阻防腐剂法与阴极保护法综合运用,可起到更好的防腐效果,其保护效率达到95%以上。

Research on Si-based Ge micro-region structure and Ge lateral PIN photodetector [PDF]
, 2016 硅基光电探测器是硅基光电子技术重要的组成部分。近年来，锗（Ge）材料由于在近红外波段吸收系数高，空穴载流子迁移率大且能与硅基工艺兼容等特性在硅基探测器领域备受关注。为进一步提高光电特性，需要在Ge层中引入张应变，而张应变的引入可以通过微区结构来得到。基于硅基Ge外延材料，构造Ge微区结构的腐蚀过程一般只对Si材料的腐蚀速率有过研究，而对材料中存在的大量位错对结构制备影响的分析却并未开展。因此，研究腐蚀液中硅基Ge样品位错的影响，提高Ge微区结构应变，对提高Ge光电探测器性能有着重要的意义 ...
