1) RMS meter
均方根测量仪
2) root-mean-square quantity
均方根量
3) root mean square measurement
均方根测度
1.
In order to study the different effects of characterizing rough surfaces with two fractal dimension methods of the structure function measurement and the root mean square measurement,fractal profile curves with different theoretical dimensions were simulated.
与结构函数测度方法相比,均方根测度方法的分维计算精度高,表征曲线的线性度好,反映分形特征的无标度区间宽,分形表征效果显著。
4) root mean square momentum
方均根动量
1.
The momentum probability amplitude and the equality form uncertainty relation of one dimensional infinite well are given,a anomalous integral formula is deduced,it show that the momentum reckoned from de Broglie formula and standing wave requirement is actually the root mean square momentum.
给出了一维无限深势阱这一特殊情况的动量几率幅和等式形式的不确定关系,导出了一个反常积分公式,弄清了根据德布罗意公式和驻波条件算出的势阱中粒子的动量实际上是粒子的方均根动量。

均方根
均方根 有时也称方均根。英语写为:root mean square（rms）.
将n个项的平方和处以n后开平方的结果，即方均根的结果。
