root-mean-square

The maximum likelihood criterion is equivalent to the minimum root-mean-square error criterion when the supposed noise is Gaussian white noise of average value of zero.

当假设干扰是均值为零的高斯白噪音时，最大似然准则等效于最小均方误差准则，求取地震子波的最大似然估计值就是求解一个托布里兹方程组。

Inrush current and over excitation of 750 kV transformer were also analyzed, a novel method of adjusting differential current phase angle of transformer for transforming from delta to wye as well as the methods of calculating frequency by software and calculating voltage amplitude by the root-mean-square were presented.

分析了750kV变压器励磁涌流和过励磁的问题，针对励磁涌流提出了Δ→Y变换调整变压器差动各侧的电流相位方法，针对过励磁问题提出了软件计算频率和均方根法计算电压的幅值；

The comparative results of noise parameter in the field were: The maximum linear peak ( 122.6-142.4dB), variability of peak and total range of A-weighted root-mean-square level with slow time constant ( LAS) in the drop-forging noise were evidently greater than those in the weaving noise;

现场噪声参数比较结果：锤锻声最大线性峰值（122.6～142.4dB）和峰值的变化以及A计权慢档均方根值（L（AS））的全距，均明显大于织布声；
