对完整岩石破裂前和既存断层粘滑失稳前的红外辐射温度场进行了遥感观测研究。发现岩石破裂前在未来断层处出现条带状的红外热像。粘滑失稳前断层团销点出现升温现象。声发射测量表明，岩石破裂前已有大量做破裂产生。地壳中的既存断层和大展前的微小破裂均可能为震前地壳中的热能转移提供通道，从而导致地面热红外展兆的出现。
Remote sensing observations of the temperature field of infrared radiation before complete rock failure and before the existence of stick-slip instability were carried out. A strip of infrared thermography was found at a future fault before the rock was broken. Viscous sliding instability before the fault point sales point appears warming phenomenon. Acoustic emission measurements show that a large number of ruptures have occurred before the rock ruptures. Both the existing faults in the crust and the tiny ruptures before the exhibition may provide a channel for thermal energy transfer in the crust before the earthquake, which will lead to the appearance of thermal infrared radiation on the ground.
