In this paper, we deducted the transform relation between seismic source parameters from seismic fault plane solution in double couple point source model and from the seismic moment.

文中推导了双力偶点源模型震源机制解得出的震源参数和用地震矩张量反演得出的震源参数之间的转换关系。

Some of the stress fields obtained from earthquake mechanism according to double couple model of earthquake represent tectonic stress field, but some of them represent the transformed stress field.

每个地震按照双力偶模型所得到的震源应力场，有的反映构造应力场，有的反映转换应力场。
