采用B - P型反向传播神经网络构成的智能化模式分类器，对此五类声发射信号进行识别，获得了满意的效果。
An intelligent pattern classifier with B-P neural network is used in recognition of those five kinds of AE signals successfully.
岩样尺寸影响其破坏模式，受加载过程裂纹初始时序不同影响其声发射活动规律表现不一致；
The AE activity is influenced by crack generation during loading process; by contrast, the AE activity is different for various rock samples as well.
