在論文中，考慮到壓力管道的一維性質，提出用應變模態改變變化率的方法對一維的結構進行損傷識別；同時考慮到在實際的工程和現場測試中，壓力管道大多深埋在地下或者有外在的保護膜，不宜進行模態的檢測，所以也考慮利用彈性波的方法對壓力管道的性質參數和截面性質進行反演識別，從而得到我們感興趣的東西，達到損傷識別；一般，在利用彈性波反射方法進行損傷檢測中，不考慮截面效應對彈性波的衰減影響，這就對損傷檢測造成一定的影響，本文考慮截面效應的影響，通過實驗來確定截面效應系數。In this paper, we design a new film stack by use of multi - frequency design idea, which decrease the film thickness of high refraction layers greatly, and the damage threshold of it will be improved hopefully. and at the base of this film stack, by optimizing the film thickness of several outmost layers, we design the hr film at 45 incidence for 632. 8nm and 1315nm with 180 ? or 90 phase retardance at 1315nm
