摘要
提出岩石声发射特征参数的表达形式和岩石声发射特征参数随时间的表述规律。岩石声发射特征参数应根据声发射脉冲和按频率展开的振幅谱都不连续的特点定义事件频度和声发射能率。
The form of parameter of acoustic emission in rock and the law of parameter variation with time are described.The event frequeney and the rate of energy of acoustic emission under rock failure are defined according to the fact that the pulse and vibrate pendulum of A.E.are not continuous.
