摘　　要：在等温过程加载的条件下 ,实验得出岩石的红外辐射能量随压力变化显著变化的结果。这个变化与温度无关 ,完全由压力引起 ,这就证明了机械能能直接激发岩石分子振动态能级之间的跃迁 ,不需要经历岩石生热的中间物理过程。这一物理现象的发现 ,为用红外遥感观测地球表层应力场分布和预测地震奠定了理论基础 ,提供了实验依据。提出了由温度异常引起的红外辐射能量变化和由应力引起的红外辐射能量变化以及将两者分离出来的理论与方法 ,进而反演介质的温度和应力 ;提出了红外遥感预测地震的两种物理机理。The result of experiment has shown that the infrared radiation energy of rock changes obviously with pressure change under the condition of isothermal process loading. The energy change is irrelevant with temperature and is caused only by the pressure, so it is proved that the mechanical energy can directly excite the energy level jump of the rock's molecules at vibration state with no intermediate physical process of rock's generating heat needed. The discovery of the physical phenomenon lays a theoretical foundation and provides an experimental basis for the observation of the stress field distribution on the earth surface layer and earthquake prediction and forecast by means of the infrared remote sensing. In the paper, the infrared radiation energy change caused by the temperature abnormality and the stress, the principle and method of separating them from each other and further the medium temperature and stress inversion have been given. Also, two physical mechanisms of earthquake prediction by means of the infrared remote sensing have been put forward.
