提出了通过在线监测退化参数，获取继电器接触失效信息的研究方法。首先给出了航天继电器可靠性寿命试验的试验条件，论述了航天继电器接触失效的两种失效模式及其机理，分析了不同负载类型下航天继电器的触点表面形态和退化参数变化趋势，获得了退化参数反映继电器退化过程的动态信息，最后给出了失效机理分析后的结论，并对以后的工作提出一些想法和建议。

This paper proposed a method that the failure information can be acquired through on-line monitoring the degradation parameters.The paper gave the condition of life test,elaborated two contact failure modes of aerospace relays,and analyzed the surface of the contact and the tendency of the degradation parameters in different load types.And digging in deep degradation parameters to reflect the dynamic information relays ’ degradation process.Finally,the paper proposed conclusions after the analysis,and gave some suggestion and ideas for future work.
