stationary random distribution

基本解釋

The features of energy distribution for blasting seismic wave which is short-time non-stationary random signal are analysed by wavelet transform technique.
爲(wèi)了深入研究爆破地震波特性，應(yīng)用小波變換方法對(duì)具有短時(shí)非平穩(wěn)特點(diǎn)的爆破振動(dòng)信號(hào)進(jìn)行了能量分佈特征分析。
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.
