如果接触电阻的变化是继电器失效的主要原因是可以的，只要有明显的可测量的变化点就用来进行退化分析，前提是你需要定义一个接触电阻的失效点，计算也需要借助一些专业软件。
Degradation analysis involves the measurement of
performance data that can be directly related to the presumed failure of the product in question. Many failure mechanisms can be directly linked to the degradation of part of the product, and degradation analysis allows the analyst to extrapolate to an assumed failure time based on the measurements of degradation over time.
有失效阈值的。你能说下继电器接触电阻的退化趋势是什么样的吗？
