相位常数 meaning in Chinese

phase constant
phase-constant

Acoustic phase constant
声相位常数
A perturbation method by tight - binding approximation which provide the relation of phase constant and angular spectrum of fields of in - waveguide is presented . the strip width of phase constant can be given . on the other hand , the group delay - time due to the k dispersion in single - mode transmission can also be estimated
提出一种利用紧束缚近似的微扰法计算阵列波导的相位常数与输入光角谱的关系，由此算出相位常数的带宽，并利用衍射方法估算单模传输中k色散引起的群延时。
