摘要
本文作者介绍了声发射源定位的测试方法，推导了时差测量公式，设计了时差测量电路。
In this paper, at first the measure method of locating admeasure echo source is introduced. Then the formula of measuring time difference is infered, and the circuits of measuring time difference is designed. At last summarised the method of measuring time difference on many channel test instrument.
