The comparative investigation of the characteristics of deformation and AE were conducted and the results are presented as followed: 1. The characteristics of rock AE are correlated to the strength, joints, cracks, and the size and hardness of crystalline grain. 2. The sequence of AE can be divided into four phases: beginning phase, tempestuousness phase, drop phase and dreariness phase. The loss and the duration of the phases are correlated to the rock character and flaws in the rock. 3. The AE rate characteristics are not almost concordant with the AE energy rate. 4. Besides the homogeneity, the strength of rock contributes the activity of AE. The higher the strength is, the lower the activity is. 5. There is a dreariness phase before the failure of most kinds of rock. 6. Whether the precursor is obvious is correlated to rock the character, and the precursor of AE rate is more apparent than the precursor of AE energy rate comparatively.

通过对比研究这六种不同岩石的变形和声发射特征发现,岩石声发射受到岩石强度、节理裂隙和晶粒软硬大小等的影响;岩石声发射过程存在初始区、剧烈区、下降区和沉寂区,各个阶段是否存在及持续时间与岩石强度、内部缺陷等有关;岩石的声发射事件率特征与能量率特征并不完全一致;岩石的声发射活性除了受其均匀性影响外,还受到岩石的强度影响,强度越小,声发射活性越强;大多数岩石破坏前存在一声发射沉寂区;岩石的破坏前兆是否明显跟岩性有关,相比较而言,岩石破坏时的声发射率前兆比声发射能量率前兆更为明显一些。

Methods: 1. Devising and making the presacral haemostatic thumbtack projector and the thumbtack: On the basis of the mankind presacral camber, the projector is made of stainless steel, and the thumbtack is made of Ti-6Al-4V alloy.
