泵浦系统 meaning in English

pumping system

By numerical calculation of the solution , in chapter 3 , we give nonlinear theory of the open v - type system with a monochromatic incoherent pump . the chapter comprises sections of resonant nonlinear theory and off - resonant nonlinear theory
利用解析解的数值计算，第三章讨论了单色非相干泵浦系统的非线性理论，包括共振的非线性理论和失谐的非线性理论两节。
In chapter 4 , we study nonlinear theory of the open v - type system with two - color incoherent pump . in this chapter , we discuss the conditions for the onset of lwi and the stability of the system in the limit of strong driving field , and the effect of incoherent pump rate rt on the gain , dispersion and population differences . we also discuss the effect of nonlinearities and the effect of pumping rate threshold of the pumping field
接着第四章讨论双色非相干泵浦系统的非线性理论，分析了强驱动场情况下的lwi产生的条件和稳定性、非相干泵浦速率r ~ 1对增益、色散和粒子数差的影响；讨论了该系统的非线性效应和非线性对非相干泵浦速率r ~ 1与r阈值关系的影响。
