真空中絕緣子沿面閃絡現象是制約高功率微波管、脈沖功率開關、高能粒子加速器等系統性能的主要原因，這是因為真空中絕緣子在一個比自身及相同真空間隙擊穿電場低得多的電場下就發生了表面閃絡的緣故，研究真空中絕緣子沿面閃絡現象及其形成機理對于改善和提高系統性能有重要意義。( 3 ) volume shrinkage of composite decreases greatly with wpu increasing, even can arrive a negative number, but thermal stability is still good. ( 4 ) toughening mechanism is that : the formation of high molecular linear amino formate construct is the toughening reason ; hydroxyl - terminated pu - prepolymer and pf react to produce chemical bond effect which participate cure ; carboxyl - terminated pu - prepolymer and pf form semi - ipn which make toughened pf occur maximum
（ 4 ）通過紅外光譜對pf / pu共混物分子結構進行的定性分析、以及掃描電鏡對沖擊斷面形貌進行的分析，可證明聚氨酯預聚物增韌酚醛樹脂的機理是：兩個體系都是由於高分子量的線形氨基甲酸酯結構而增韌；端羥基pu與pf在共固化中產生化學鍵效應，參與pf的固化；而端羧基pu則與pf形成半互穿網路而增韌。The microstructure observation in the microfissures suggests the liquation microcrack results from grain boundary liquation by constitutional liquation of mc carbides and formation of continuous and or semi - continuous low melting liquid films, however, the occurrence of the solid state microcracks can be attributed to the effect of ultrafast transit thermal shock introduced by high energy electron beam
液化裂紋起源於mc碳化物的組份液化而形成的晶界連續或半連續的低熔點共晶液化膜，固相裂紋形成的則是高能電子束流的快速瞬態熱沖擊效應的直接結果。Finally, a compact uwb pulse source composed of pzt95 / 5 ferroelectric ceramic, a 50 coaxial transmission line charged by a pulse transformer, a peaking - chopping switch, a coaxial matched load and a pulse diagnostic system was built and tested, which can produce pulse voltage on a matched 50 load with peaking voltage of 100kv, rising time of 870ps, falling time of 670ps, and fwhm of 1. 410ns
