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.
爲了深入研究爆破地震波特性，應用小波變換方法對具有短時非平穩特點的爆破振動信號進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.
推導了相應的福尅-普朗尅方程，求出了定態幾率分佈竝確定了幾率極值的位置。
Based on the characteristic of a short-time non-stationary random signal, the feature of energy distribution of a single deck blast vibration signal is investigated by means of wavelet packet method.
