摘要/Abstract

摘要： 根据地震孕育、发生过程中岩石破裂的特点, 提出了电磁辐射的有限移动源模型, 推导了均匀介质中矩形和圆盘形破裂的矢量磁位计算公式, 通过对式中的一些物理参数及有关问题的讨论, 说明不同形状、不同破裂方式的电磁激励源的辐射, 是地震电磁观测不确定性的一个重要原因.

Abstract: According to the characteristics of rock rupture before and when earthquakes happen,a finite moving source model of electromagnetic radiation is put forward and the calculation formula of vector magnetic potential for disk source and rectangle source in homogeneous medium is derived.Some parameters and problems about are also discussed,and it is suggested that radiant points with different shape and different failure ways bring about uncertain electromagnetic observations related to earthquakes.

Key words: earthquake, electromagnetic radiation, finite moving source
