摘要
对不同岩性的岩石进行了无源微波遥感用于地震预测的实验研究，实验在等温过程加载条件下进行．实验得出岩石的微波辐射能量随岩石的应力状态变化而显著变化，这个变化完全由应力引起，与温度无关．将介质所处的应力状态同介质的微波辐射能量变化与物理机理直接地联系了起来，为无源微波遥感观测地球表层应力场分布和预测地震奠定了物理基础，并提供了实验依据．本文提出了无源微波遥感预测地震的两种物理机理，即热能激发机理和机械能激发机理；提出了由无源微波遥感探测结果，反演介质应力状态和温度状态的方法．
A simulation experiment research of the application of passive microwave remote sensing technology to the seismic prediction was carried out for rocks of different lithologic charasters. The experiment was carried out under loading condition during the isothermal process. The experiment results that the microwave radiation energy of the rock changes obviously with the change of its stress state, These changes are caused completely by stress and has nothing to do with temperature. So the stress state of the medium and the microwave radiation energy changes of the medium are linked up directly in physics. The discovery establishes the physical foundation and provides the experimental basis for the observation of the stress field distribution on the earth surface layer and seismic prediction with passive microwave remote sensing technology. Two physical mechanisms of predicting earthquake with passive microwave remote sensing technology are put forward in the article, i. e. heat energy excitation mechanism and mechanical energy excitation mechanism. A method used to infer medium stress state and temperature state from passive microwave remote sensing detection is given in the article.
