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。In this paper we discuss the three dimensional quasi static problems by using the magneto thermo elasticity theory, which is related to geotherm: the situations of the heat carrying fluid intruding into the vertical or horizontal cracks, and the case of static local high temperature regions. After giving their approximate expressions, we focus on the space time distribution of perturbation of magnetic field. Lastly, its application in theoretical study of seismology is emphasized.
