摘要: 按照Priestly提出的演变随机过程理论，对非平稳随机过程的演变功率谱密度函数进行了理论推导，并给出了定义。在此基础上，建立了基于均匀调制随机过程的爆破地震动演变功率谱密度函数。经对比发现，理论模型计算值与实验测试结果具有较好的一致性。

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.
