  1. A highly efficient numerical algorithm by using multi - grid method ( mgm ) is introduced to solve the three dimensional field distribution in the present paper. formulae of the restriction and prolongation in mgm computation is deduced, and a 3d program of mgm is accomplished, which can solve the field distributions in electron optical systems for various electrostatic lenses. the 3d field distribution in an electrostatic concentric spherical model is tested with mgm algorithm and an algorithm based on finite difference method ( fdm ) respectively. comparing these two results in view of computational efficiency and computational accuracy, it appears that mgm is superior to fdm in solving electrostatic field distribution for the electron optics problem. this paper shows that the 3d field computation using mgm greatly improves the computational efficiency of field distributions in electron optical systems and shortens the computational time

    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。
