  1. A normal transform is introduced, and there are enough much grids in the region between the critical layer and the wall, where the variation of the disturbance is the quickest. the finite - difference of governing equations with fourth - order accuracy in the normal direction is utilized in full regions including points close the wall, and is very important for accurately discreting equations. the combination of global and local methods is implemented, and a new iterative formula is derived

    對于曲線坐標系下的拋物化性方程,文中發展了求解的高效數值方法:引進法向變換,使得在臨層與壁面之間的擾動量變化最快的有更多的法向網格點;導出包含邊在內的完全四階精度的法向有差分格式,這對方程精確離散至關重要;採用全局法和局部法相結合的方法及其新的迭代公式,大大加速收斂並得到更精確的特徵值。
  2. When discreting the sonic and elastic analytic equation, the paper shows different finite - difference forms of sonic and center finite - difference form of elastic by detailed deriving in different situation. at the same time, the paper discusses the finite - difference ' s stability and the boundary conditon of gridding region, then lists the final sonic and elastic finite - difference expression which can realize forward modeling and inverse in computer by programming

    在對聲波與彈性波解析表達式進行離散時,論文按不同情況進行了詳細的推導,由此得到聲波方程各種不同的差分格式和彈性波的中心差分格式,在此基礎上還對差分方程性條件與網格處理進行了討論,最後得到完整的能在計算機上進行正反演編程運算的聲波與彈性波有差分格式。
