| 英文摘要: |
| With the availability of high speed personal computers with large storage and random access memory, simulation of UNDT can now be done widely. A review of the progress in mathematical models and methods used in UNDT is given in this paper. The models and analytical method of mutiGaussian, acoustic ray, diffraction theory, EFIT etc, as well as the numerical methods including the finite difference method (FDM), the finite element method (FEM) and the boundary element method (BEM) are discussed. |
