Dianci bileiqi, 2006 介绍了国内外棒形悬式复合绝缘子金属附件连接区的设计结构,从不同厂家芯棒、压接力和生产工序三方面研究了连接区采用压接式结构对产品机械性能的影响,提出了在设计连接区时应考虑圆度、连接区的长度、端口的密封性、压块的长度及壁厚等因素。通过试验,认为压力小,易抽芯;压力大,易损伤芯棒。进行二段硫化后,强度降低了约20%,经原压力补压后,连接区强度可恢复,强度配合合理。推荐70kN级压力值可控制在（12.5～13.0）MPa,100kN级压力值可控制在（20.0～20.5）MPa以及160kN级压力值可控制在17 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 1999 目的: 探讨外伤性面瘫适当的处理方法。方法: 对 12 例外伤性面瘫的病例施行手术治疗,损伤部位于面神经迷 路段及膝状神经节周围 3例次、水平段 6例次、垂直段 4 例次、颅内段 1 例次。经乳突、上鼓室进路 10 例,经颅中窝、乳突联合 进路2 例。结果: 术后随访半年～ 3 年。面瘫Ⅰ级恢复 7 例, Ⅱ级恢复 2 例, Ⅲ级恢复 2 例, Ⅳ级恢复 1 例。结论: 外伤性面瘫 应及早手术,乳突上鼓室进路基本上可暴露膝状神经节及迷路段远端, 但术野狭窄, 对膝状神经节减压不够完全, 且影响听 力 ...

Dianci bileiqi, 2017 电力变压器的内绝缘在雷电过电压的多次冲击下产生累积效应,影响其绝缘性能。研究表明实际雷电入侵波存在双极性衰减振荡波形的情况。首先用不同频率的双极性振荡衰减波波形,取低于其击穿电压的电压值,对油纸绝缘试品进行累积冲击,绘出其V-N特性曲线,验证了累积效应的存在性,探索了V-N特性的规律;继而用宽带频谱介电测试仪对在双极性振荡衰减波作用下累积冲击了100、200、300以及并未受冲击的绝缘纸进行测试,并对比分析了四种情况下复相对介电常数和介质损耗角正切值的变化规律,验证了累积效应对油纸绝缘的损伤 ...
