【摘要】 本文研究了青藏块体东北缘４个测点断层气体的异常变化与地震活动的关系。１９９２年─１９９３年各测点断层气组分普遍出现异常，主要表现为测值突跳、上升变化，各测点及各组份异常有明显的同步性特征。本文着重介绍了１９９３年１０月２６日托来６．０级地震前多观测，点断层气体的异常情况。最后，本文还对断层气体的场效应作了初步探讨。更多还原

【Abstract】 In this paper,authors studied the relationship between seismicity anomalous changesof fault product gases at 4 measuring points along the northeastern margin of Qinghai-Tibetplate. The anomalies of fault product gas components appeared at these measuring points from1992 to 1993,for example,sudden change and rising of the observed values. The anomalies ofvarious components or/and at various measuring points have obvious synchronism. Authorsmainly introduce the anomalies of fault gases observed at many measuring points before theTuolai M 6. 0 earthquake occurring on Oct.26,1993. At last, the field effect of fault productgases is discussed preliminarily.更多还原
