| 摘 要： | 将对材料声发射的研究，力学过程的研究，同对材料断裂损伤等破坏过程的研究相似结合，提出了声发射过程的概念。给出定量考察声发射过程的自相似性特征函数。并在此基础上，根据混凝土试块的三点弯曲试验，确定出了混凝土试块断裂的声发射自相似性识别特征。

| Abstract: | In combination of studies on AE and mechanical process with that of fracture and damage of material, the concept of AE process is proposed. A selfsimilar characteristic function is provided to quantitatively investigate selfsimilarity of AE process. Based on the study, the recognition characteristics of AE selfsimilarity is provided at critical fracturing of concrete under three point bending experiments. |
