contact fault造句

• It is educed that contact fault was a main mode of failure of electrical connectors , and the two main factors which affect the contact fault are temperature and vibration stress . the failure mechanism of electrical connectors under the two stresses is discussed
  经分析，接触失效是电连接器的主要失效模式，而影响接触失效的最主要因数是环境温度和振动应力，对电连接器在两应力作用下的接触失效机理进行了探讨。
• Secondly , through analyzing the failure instance of electrical connectors in using and testing environment , educed contact fault was a main mode of failure of electrical connectors . on natural working conditions , the main reasons which caused fault of electrical connector were contact stress decreasing , microseism wearing and tearing and surface film growing
  而在正常的工作条件下，造成电连接器电接触失效，即决定电连接器工作寿命的主要原因是接触压力减小、微动磨损和表面膜层的生长，而影响接触压力、微动磨损和表面膜层变化的主要因素是环境振动和温度。
• Secondly , been generalized the failure data of electrical connectors from working and testing environment , electric contact failure , insulation failure , mechanical connection failure and other failure are four mainly failure modes of connectors , moreover , built the faulty - tree to analyze their reliability level . however , contact fault failure was the most prevalent mode of electrical connectors . under natural working and reserving conditions , the contact stress decreasing , fretting and surface film growing are mainly reasons to make electrical connector failure
  其次，通过对现场、试验场电连接器的失效情况进行统计和分析，总结出电连接器的四种主要失效模式：电接触失效、绝缘失效、机械连接失效和其他失效，并对电连接器进行了故障树分析，指出电接触失效是电连接器失效的主要形式，而在正常的工作条件下，造成电接触失效，即决定电连接器工作寿命的主要原因是氧化膜层的生长、接触对磨损以及磨损腐蚀物的堆积，而影响氧化膜层的生长、接触对磨损以及磨损腐蚀物堆积的主要因素是环境振动和温度应力，为电连接器进行失效机理分析奠定了基础。
