【摘要】 地震孕震体是一个非线性双稳整（或多稳整）系统，具备发生随机共振的条件。而地震的孕震过程与发生现象表现为小功率（一定的能量，长时间的过程）的能量输入和大功率（一定的能量，极短时间的过程）的能量输出。本文用随机共振理论，解释了这一特征。更多还原

【Abstract】 Seismogenic body is a non-linear bistable(or multistable) system with condition of random resonance,and earthquake preparation and occurrence process appears in the character of inputting energe with small power in long period into the system and exporting energy with large power in extremely short period out of the system.In this paper,we use the theory of random resonace to interprete the character.更多还原
