扩大量 meaning in English

extensive magnitude

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。
