stationary random distribution

基本解释

The features of energy distribution for blasting seismic wave which is short-time non-stationary random signal are analysed by wavelet transform technique.
为了深入研究爆破地震波特性，应用小波变换方法对具有短时非平稳特点的爆破振动信号进行了能量分布特征分析。
The corresponding Fokker-Planck equation is derived and the stationary random distribution has been obtained and the positions of the extremum for the distribution are determined.
