<正>In order to know much more about the characterization of electromagnetic radiation induced by rock fracture, assumes that the electromagnetic radiation is created by the atomic perturbation during rock fracture, and uses the Crack Opening Displacement method to calculate the crack width, this paper finds out the ration relationship between the frequency and the elastic parameter. Creates the Infinity Flat with Impenetration Crack Model, this paper work out the frequency range of the electromagnetic radiation during several rock fracture which is from middle to high frequency. The results indicate that the frequency is changed with the elastic parameters.
