试验结果表明，三种试验均造成了试验后期欧姆接触电阻增大，最后导致欧姆接触失效。

It has been shown that all three tests have caused the ohmic contact resistance to increase at the end of the tests, which leads to the failure of the contact.

接触电阻一般非常小其范围在微欧姆到几个欧姆之间。

This resistance is normally very small, ranging from micro-ohms to a few ohms.

对于大多数的应用来说，微欧姆计或数字多用表足以用来进行接触电阻的测量工作。

For most applications, the micro-ohmmeter or DMM is sufficient for contact resistance measurements.
