  2. The development from traditional research of layered media to heterogeneous anisotropic media and to random media, is required to solve the problems in petroleum exploration

    摘要從傳統的層狀介質研究發展到對非均勻各向異性介質乃至隨機介質研究，是解決當今高難度油氣勘探和高標準油氣開發問題的需要。
  3. The psm was extended to heterogeneous anisotropic medium and a program for 2d elastic waves propagation was written in fortran. the stable condition of psm for 2d anisotropic media was introduced and discussed. the propagations of elastic waves, excited by point sources in homogeneous isotropic / anisotropic rocks, were simulated
