root mean square deviation

基本解释

Cpm is an overall capability index defined as the ratio of the specification spread (USL - LSL) to the square root of the mean squared deviation from the target.
Cpm是一个总体的能力指数，定义了均值偏离目标值的均方差的平方根和规范宽度的之间的比值。
The calculation methods for root-mean-square deviation of concrete strength and mortar strength tested by rebound method are different founded through the comparison of the two methods.
通过对回弹法检测混凝土强度、砌筑砂浆强度方法的比较，发现其计算标准差的方法有所不同。
Kalman-Filter-based optimal observation scheme is a Bayesian method, which improves observation locations by minimizing the expectation of the root mean square deviation(RMSD) of the analysis field.
最优观测方法是一种不需要直接同化观测，而通过最小化分析场误差方差理论值来选择最优观测点的方法。

What we want to do now is compute the mean and variance of the portfolio-- or the mean and standard deviation, since standard deviation is the square root of the variance-- for different combinations of the portfolios.
我们现在要做的是,计算这个投资组合的均值和方差-,或者均值和标准差，因为标准差的平方就等于方差-,这对任何投资组合都是一样的。
