预测继电器触点接触电阻的研究对于预测其接触可靠性，乃至预测其整体可靠性均具有非常重要的意义。

The prediction study on the contact resistance of relays is very significant to that on the contact reliability of relays, even to the whole reliability.

采用该方法可以区分触头表面污染状态，并根据接触电阻的变化规律及其变化值的大小评价触头接触可靠性。

Based on the new method the distinguish could be made between "clean" contact and "unclean" contact, and we should predicate the contact reliability of relay according to the value of contact...
