摘要： 以磁热弹性理论为工具,讨论与地热有关的三维准静态问题: 载热流体侵入竖直或水平裂隙的情况和存在静态局部高温区的情况。在求得其近似解后,着重讨论其扰动磁场的时空分布。最后指出其在地震理论研究中的应用。

关键词: 磁热弹性力学, 准静态, 地震孕育

Abstract: In this paper we discuss the three-dimensional quasi-static problems by using the magnetothermo elastic ity theory, which is related to geotherm: the situations of the heat-carrying fluid intruding into theverticalor horizontal cracks, and the case of static local hightemperature regions. After giving their approximate ex pressions, we focus on the space-timedistribution of perturbation of magnetic field. Lastly, its application in theoretical study of seismology is emphasized.

Key words: Magnetothermo elastic ity, Quasi-static, Seismic development
