歪度 meaning in Chinese

skewness

Slice signal - to - noise ratio ( ssnr ) and the sksnr are firstly defined and their mathematical formulas are obtained
首次提出了切片信噪比、歪度信噪比等概念，推导了其理论计算公式。
5 an algorithm of skew signal - to - noise ratio ( sksnr ) based quadratic phase dynamic coupling signal extraction is created
5提出了基于歪度信噪比的二次相位动态耦合信号的多谱特征提取算法。
The theoretical analysis and simulation show that the ssnr and the sksnr are equal to or greater than the original signal - to - noise ratio ( snr ) , and that employing third order cumulant slices can effectively extract the mot - radiated quadratic phase dynamic coupling signals from asymmetrical distribution noise
理论分析与仿真表明：切片信噪比、歪度信噪比总是大于相关信噪比；用该算法十分有效地实现了二次相位耦合信号与非对称分布色噪声的分离。
