  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。
• The reasons focusing only on ray travel times are " noise tolerance could be enhanced and the sensitivity to the environment model mismatch may be reduced by neglecting amplitude information ; phase ambiguity is eliminated by employing the group delay of arriving wave packets ; travel times are pseudo - linear functions of sound speed profiles of the medium , and the perturbation of ray travel time is much smaller than sound pressure ' s
  之所以选择声传播时间的原因是：噪声容限可以得到提高，并且传播时间的计算可以不考虑声压的信息，从而降低了对环境模型失配的敏感性；相位的起伏也可通过到达包络的群延时来消除；传播时间是介质声速分布的伪线性函数并且传播时间的起伏远小于声压的起伏。
