| 摘 要： | 本文利用主应变比异常理论分析了祁连建站以来地应变观测资料，认为肃南──祁连断裂段上及附近发生的地震是由于构造应力场的变化，在引张应力状态下，正断层或走滑断层易于活动而导致的。

| Abstract: | Analyses of observed ground strain dstum by the abnormal theory of Principal strain ratio from 1990. 5 to 1992. 10 show that the earthquake on the Sunan-Qilian fault or nearby resulted from the change of structural stress field, but the change caused the activity of normal or strike-stip fault in the tension stale. |

| Keywords: | Principal strain ratio Ground strain Stress field |
