根据裂纹尖端微裂纹密度理论，假定声发射总数与裂纹尖端的显微裂纹总长度成正比，推导了出了岩石裂纹稳定扩展时声发射总数与应力强度因子之间的关系式。将并一些试验结果与理论推导进行了比较，结果表明；理论推导与试验结果大体一致。

Based on the crack tip microcrack density theory

a supposition that total AE count is directly proportional to the total microcrack length is proposed

a relationship between total AE count and stress intensity factor for stable crack growth is derived.With a series of experimental results

the relationship between theoretical derivation and the experimental results is compared

it shows that the theoretical derivation coincides better with the experimental results.
