一、声发射研究系统岩石受压变形过程中有大量声发射事件产生。从岩石内部发出的弹性波就称作声发射。根据岩石声发射的情况(多少、大小、频率、位置等)可以了解到岩石材料内部的破裂过程。不但使我们能够了解发声地点的情况,而且还能揭露它的更为深入的矛盾和实质。使我们不仅能够了解缺陷的目前状态,还可以了解缺陷的形成历史和发展趋势。

First, the acoustic emission research system Rock compression deformation process a large number of acoustic emission events. Elastic waves emanating from the interior of the rock are called acoustic emissions. According to rock acoustic emission (how much, size, frequency, location, etc.) can be learned within the rock material rupture process. Not only will we be able to understand the situation at the place where we sound, but it will expose its deeper contradictions and substance. So that we can not only understand the current state of defects, but also understand the history of the formation of defects and trends.
