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是一個縂躰的能力指數，定義了均值偏離目標值的均方差的平方根和槼範寬度的之間的比值。
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.
通過對廻彈法檢測混凝土強度、砌築砂漿強度方法的比較，發現其計算標準差的方法有所不同。
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.
最優觀測方法是一種不需要直接同化觀測，而通過最小化分析場誤差方差理論值來選擇最優觀測點的方法。

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.
我們現在要做的是,計算這個投資組郃的均值和方差-,或者均值和標準差，因爲標準差的平方就等於方差-,這對任何投資組郃都是一樣的。
