However, the digital random vibration control systems currently based on power spectrum fitting can only generate random vibration exciting signals with Gaussianprobability distribution.
然而，目前基于功率谱均衡的数字式随机振动控制系统只能产生高斯分布的随机振动激励信号。

The background samples are chosen by thresholding inter-frame differences, and the Gaussian kernel density estimation is used to estimate the probability density function of background intensity.
通过相隔固定的帧差值阅值化得到背景样本值，并采用高斯核密度估计方法计算背景灰度的概率密度函数。

The probability density function of velocity response of oleo damper excited by exponential colored Gaussian noise has been obtained.
