时滞对数种群差分方程正周期解的存在性与应用 - Genetic polymorphism and the population difference of 7 y - str loci and haplotypes in chinese han and japanese populations
位点及单倍型的遗传多态性和群体差异 - In chapter 5 , we make numerical calculation , then analyze the properties of the population distribution , the gain , the coherence term and population difference , and validate the transient light amplification mechanism of this system
第五章我们根据数值计算结果分析了粒子数分布、增益、相干项和粒子数差的瞬态演化过程，验证了系统产生增益的机制。 - 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。
