| 摘 要： | 提出用“两体作用”模型来研究自然界的岩体破裂换稳现象。具体分析了两冉体作用系统的失稳过程，运用微机差分计算获得了它的变形和声发射前兆规律。最后在文献［１］的声发射序列关系中引入了距离因子和随机因子，发现有些序列中出现的声发射活动相对平静是由于在两岩体相互作用过程中某一岩体弹性恢复所致。

| Abstract: | The two rocks interacting model is used to study the rock body failureand instability phenomena in the nattire. We analyzed the two rocks interactingsystem instability with differential method on computer. The distance and randomindexes are added into the acoustic emission formulation in Paper 1]. It is foundthat the acoustic emission relative quietness is due to the elastic recovery of oneof the two rock bodies. |
