Abstract: In this paper, general monitoring conditions of water temperature in our country and micro-behavior phenomena such as solid tide, co-seismic effect and precursory anomaly before earthquakes is introduced. And its mechanism is analyzed. The authors propose that the study of mechanism of water behavior should be carried out from some aspects, such as heat systems and heat process, for example, from two geotemperature gradients, two heat convections, one conductivity and one heat diffusion and so on.

Key words: Micro-behavior of water temperature, Mechanism, Geotemperature gradient, Thermal conductivity, Heat convection, Heat diffusion
