| 摘 要： | 本文研究了中国大陆１９６６年以来发生的５次大地震（Ｍｓ≥７．０）的余震活动深度与地热流的关系。研究表明，地热流较高的震源区，余震活动深度分布较浅，并且得出余震深度分布受地壳内部岩石脆性－韧性转变深度的流变学特征控制的推论。

| Abstract: | The relationship between aftershock depths and surface heat flow in the source areas of five great earthquakes (Ms>7. 0) in China mainland has been studied in the paper, it shows that the higher the surface heat flow, the more shallow the aftershock depths , and distribution of aftershock depths are under the control of the rheological mecha -nism of the rock brittle-ductile transition in the crust. |
