The property of electrical arc resistance of cuw60 is the most bad one , cuw80 takes second place , and cuw70 is the best one in this test 在本次实验条件下， cuw60的耐烧损性最差，而cuw70最好， cuw80介于两者之间。
3 . the arc erosion of cuw80 / crcu integrated contact is primary forming the thicker shell and th shell flake off . 4 摘要( 3 ) cuw8o主要是以产生较厚的以w为主的壳层，然后在电弧的反复作用下，壳层剥落，如此循环，导致触头的最终烧损。
When there are rich cu defect in cuw / crcu integrated contact , the arc eroding loss of the contact is first from the spraying of cu , then the w skeleton flake off ( 4 )在触头存在富铜缺陷时，烧损首先产生的是喷溅，接下来是钨骨架的大面积烧损。
Here is a form , consisting of articles burnt , purchase time , original price , damage degree , depreciation price . please fill out the form according to the facts 警：这里有一份表格，包括烧损物品、购置时间、原价、烧损程度、折旧价等内容，请您如实填写。

The loss of deoxidizing elements resulting from thermal decomposition of lining materials and the change of total oxygen in molten steel during vim refining are researched 摘要研究真空感应熔炼过程中因炉衬材料热分解造成的脱氧元素烧损及其全氧含量的变化规律。
There are three modes for the invalidation of cuw / crcu integrated contact : splitting from the binding interface of cuw / crcu ; uneven distortion of contact finger and severe eroding loss 触头的动态失效主要有三种方式:在结合面处发生断裂，严重烧损后无法接通，触指变形。
At present , the arc contacts in sfe switches is formed by the excellent property of electrical arc resistance of cu w alloy and the eminent conductivity together with high elasticity of crcu alloy , so - called cuw / crcu integrated contact 目前在sf _ 6断路器中普遍使用的触头材料一般由耐电弧烧损的cuw部分和提供弹性和导电性的crcu部分组成，即cuw crcu整体触头。
2 . the arc erosion of cuw70 / crcu integrated contact is first from the even volatilization of the surface cu , following by the formation of a w shell on the surface of w skeleton , then the shell flake off , after this , new arc erosion occur ( 2 ) cuw70的烧损先是表层的cu均匀挥发，接着在骨架的表面形成一层以w为主的壳层，然后壳层剥落，裸露出来的继续烧损，如此反复，导致了触头的烧损。
