But the actual signals which we get in practise usually are non-stationary and non-Gaussian distribution, specially when the fault occurs.
而实际测得的信号大量是非平稳和非高斯分布的信号，尤其是在发生故障时更是如此。
As the ideal mathematical model for non-Gaussian impulsive noise, a -stable distribution has been the focus of intensive research in signal processing fields.
稳定分布作为非高斯脉冲噪声的数学模型，已经成为信号处理领域的热点研究课题。
The soil as of the study area was positive skew distribution, tally with second steps stable supposed, after Gaussian non-liner change.
结果表明，研究区土壤砷为正偏态分布，经高斯非线性转化后，符合二阶平稳假设。
