• 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
  提出一種利用緊束縛近似的微擾法計算陣列波導的相位常數與輸入光角譜的關系，由此算出相位常數的帶寬，并利用衍射方法估算單模傳輸中k色散引起的群延時。
• 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
  之所以選擇聲傳播時間的原因是：噪聲容限可以得到提高，并且傳播時間的計算可以不考慮聲壓的信息，從而降低了對環境模型失配的敏感性；相位的起伏也可通過到達包絡的群延時來消除；傳播時間是介質聲速分布的偽線性函數并且傳播時間的起伏遠小于聲壓的起伏。
