  1. Asymptotic direction and asymptotic curve of spacelike surface in r

    1中類空曲面的漸近方向與漸近曲線
  2. The important parts of this work consist of : 1. the high frequency asymptotic evaluation of wave equations in nonhomogeneous medium by maslov ' s method is systematically studied, and formulations of the high frequency asymptotic evaluation in nonhomogeneous medium which varying only in one direction are constructed

    本論文的工作作為國家自然科學基金地震波傳播與成像項目( no . 40174032 )的一部分,得到如下結果: (一)論文分析了利用maslov方法求解非均勻介質中波動方程高頻近似解的基本原理和求解過程,構造了介質系數只在一個方向變化時波動方程高頻近似解的通用計算公式。
  3. Since the cause of caustics phenomena is that the tangent plane of lagrange submanifold in caustic fields is perpendicular to the original physical space, we solve the high frequency asymptotic problem in a new mixed space by changing the projecting direction, then we get the high frequency asymptotic solutions of wave equations efficiently near and on the caustics

    由於出現焦散現象的原因在於lagrange子流形在該處的切平面與物理空間垂直,通過轉換適當的投影方向,然後將這個投影方向上得到的高頻近似解再變換回到原來的物理空間中,得到了在焦散附近適用的高頻近似解。
