Abstract

Abstract

According to Priestly evolutionary random process theory, the evolutionary power spectra density function of nonstationary random process is presented by theory method. By means of nonstationary random evolutionary theory, the evolutionary power spectra density function of blasting seismic is suggested on the basis of uniformity modulating random process. Compared with experimental results, the suggested theoretical models are coincided with experimental phenomena and data.
