触点的电侵蚀是决定汽车继电器工作寿命和可靠性的主要因素，在对汽车用继电器触点电侵蚀进行论述的基础上，引用美国查克（Ｃｈｕｇａｉ）研究所韦特（Ｗｉｔｔｅｒ）等人的试验研究成果，获得了触点闭合和断开瞬间过渡过程的参数，对一些被人们忽略而又明显影响触点电侵蚀的因素进行分析，给出了技术数据，提出了汽车用继电器电侵蚀和电寿命试验规定条件中应注意研究的问题，供国内有关生产厂家、使用单位和工程技术人员参考。
Electrical erosion of contacts is the main factor that determines the working life and reliability of automotive relays. Based on the discussion of the electrical erosion of contacts for automotive relays, the reference to the study by Witter et al. Of the Chugai Institute of America The experimental results show that the parameters of contact closing and breaking instantaneous transition are obtained. Some factors neglected by people and affecting the contact erosion are analyzed. The technical data are given, and the electrical erosion and Electrical life test conditions should pay attention to the research issues for domestic manufacturers, the use of units and engineering and technical personnel for reference.
