本文在時間序列坐標延遲后重構的相間中，作出重構函數的等價定義，提高了預測的可操作性；並在此基礎上，引入了加權距離來刻畫預測向量的鄰近點，保證了鄰近點的相似性。Based on the nonlinear parabolic approximate wave reflection - diffraction equation of mild slope, a model of wave propagation on a fan - shaped coordinate is put forward considering winds, bottom friction and wave breaking, etc. the existing calculation shows that the model can be employed to determine wave fields in large water areas
接著以非線性的拋物型近似波浪緩坡方程為基礎，提出了扇形坐標下的波浪傳播模型，模型包括了風、底摩阻、波浪破碎等因素的影響，可以用於大水域的波浪場的確定；文章最後介紹了一些計算算例。Secondly, the problem of the curve - surface mutual transforming and smooth - finishing have been analyzed farther. for the surface intersecting problem : owing to the introduction of the boundary points, as long as the intersecting points on a certain line, the full intersecting line can be gained. the intersecting line either intersects at the boundary of the triangle surface or forms the loop ; during the course of tracking, the selecting of the pace is restricted by the curvature, the number of the gained intersecting points are not in proportion as the chord - length ; the intersecting points not only record the coordinate and store the parameter
對兩曲面求交問題，當曲面細化足夠小時，曲面求交可近似看成曲面與平面相交問題，引進了邊界點的概念，因此只要知道交線上的任意點，就可以將跨越許多曲面片的整條交線計算出來，所求出的交線或者跨越曲面的邊界，或者形成交線環；從初始點出發跟蹤求解整條交線的過程中，步長的選擇採用了通過曲面片曲率來約束的方法，用該方法求出的交點在不同曲面片上的分佈數目不與弦長成正比；該求交方法包含了各曲面片的邊界線與交線的交點的求解，可獲得邊界交點的坐標值及其參數值。In chapter six, we studied the nonlinear solitary wave solution under the transverse perturbations for a system of coupled nonlinear electrical transmission lines. in the continuum limit and suitably scaled coordinates, the voltage on the system is described by a modified zakharov - kuznetsov equation

視差紋理映射技術是新近提出的實現物體表面粗糙感的一種凹凸映射技術，它是對目前因計算量過大而無法應用於實時渲染系統中的位移映射技術的改進，這種技術不是對物體表面的頂點進行偏移，而是藉助于高度圖對紋理坐標進行偏移，從而近似達到位移映射技術的效果。In this thesis, we for the first time corrected the thrust axis to qq direction using mc simulation, and in this way eliminated the systematic errors coming from the difference in thrust and qq directions
