摘要
介绍连续型声发射信号的区域定位方法、衰减测量定位方法、互相关式时差定位方法和干涉式定位方法 。
The zone location, signal amplitude measurement, cross correlation and interference techniques for continuous acoustic emission sources are systematically introduced. Those factors producing error in continuous acoustic emission source location are analyzed.
