It shows that the viscosity offers only little effect on lower mode of dispersion curve, and it effects on higher mode of dispersion curve with the increasing of damping.
理论计算发现粘弹体的粘滞项对频散低阶模式影响不大,但随着粘滞的增大对高阶模式可产生影响。
Although small QW has smaller optical confinement factor and smaller ratio of carriers injected into QW, it can provide higher mode gain because of its smaller mixing between valence bands.
小阱宽的量子阱虽然光学限制因子和载流子注入比例都较小,但由于其价带耦合小于宽量子阱,从而具有高的模式增益,说明量子阱的能带结构对其光学特性有决定性的作用。
The numerical results indicate that the higher-order mass matrices have a negligible influence on the fundamental frequency, but they affect the frequencies of higher mode vibrations considerably.
数值实验结果表明:高阶质量矩阵对横向振动基频及低频的影响可忽略不计,但它们对高阶横向振动频率有很大的影响。
