相对功率 meaning in English

relative capacity
relative power

Based on the six - port relative power theory that for a given load the relative power ratios of different ports are left unchanged with the input power to the six - port varied , characteristic parameters of detectors can be obtained through the least - square method
根据六端口相对功率理论即对某一负载各端口相对功率比值不随输入功率变化，由最小二乘法得到检波器的特征参数，结合四标准法，确定六端口网络的系统常数。
On the basis of analyzing the output signal of a two wavelength beat - wave absolute distance interferometer , this paper proceeds from the realities of the aiming method of the beat - wave interferometer , conducts an analytical investigations on the dependence of the aiming accuracy of the beat - wave interferometer on laser dual - line output power equilibrium , propose two new concepts - a basic aim blind area and a blind area expansion , and establishes an analytical expression between the blind area expansion and the relative power difference of laser dual lines
本文从拍波干涉仪对准方法的实际出发，在分析双谱线拍波干涉仪输出信号的基础上，研究了双谱线功率不一致与拍波干涉仪对准精度的关系，提出了基本对准盲区和盲区扩大量的新概念，建立了描述盲区扩大量与双谱线相对功率差之间关系的解析表达式。
