response rms values 响应均方根值
Using the multimeter, measure and record the rms values of the input as well as the output (volts) in table E2-2.
用万能表测量并记下表E2-2中输入量和输出量的有效值（伏特数）。
Its main ideas are that the AC waves are described through some AC instantaneous values in a period, and then RMS values and other concerned parameters are worked out.
它的主要思想就是在一个周期内用若干个交流信号瞬时值描述该交流信号波形，并计算出有效值及其它有关参数。
The structural FEM model is set up for the ultra-thin mirror with support structure. PV and RMS values of the mirror with horizontal or vertical optical axis are gained.
建立结构模型，对带有支撑结构的超薄反射镜进行分析，得出在光轴竖直与水平两种状态下的PV和RMS值。
