  1. Firstly , we want to solve the problem that based on the background of some numerical problem . it is the special nondifferentiable optimization problem
    本文首先來解決以某些數(shù)值計算問題為背景提出的一類比較特殊的非光滑優(yōu)化問題。
  2. In recent years , nonlinear methods have attracted more and more attention and there have been some successful cases , such as median filter , mathematical morphology , etc . as a preferred way to inverstigate nonlinear numerical problems , the continued fractions method can effectively express the gradually changing data or abrupt data , so it is meaningful to study image processing by means of the continued fractions theory and algorithms
    近年來在圖像處理領域，利用非線性方法進行圖像處理取得較好效果的有中值濾波、數(shù)學形態(tài)學等，非線性方法已引起越來越多研究者的重視。作為研究非線性數(shù)值問題的首選方法?連分式方法，不僅能反映數(shù)據(jù)的漸變性，也能反映數(shù)據(jù)的突變性。鑒于這些原因，本文將連分式插值和逼近引入到數(shù)字圖像處理領域，開展了圖像插值、圖像重建等方面的研究。
  3. An improved finite volume technique and total variation diminish scheme has been presented for solving the numerical problem with complex flow gas and space time processing synchronously , based on analysis of some numerical method for increasing the convergence , precise and strong capture capacity of shock wave
    針對高壓sf _ 6斷路器氣流場求解的復雜性和特殊性，在對常用氣流場數(shù)值求解方法應用特點分析的基礎上，本文采用改進的有限體積tvd格式進行斷路器氣流場數(shù)值求解，提高了解的收斂性、準確性和激波的捕捉能力。
  4. This paper introduces the basic concepts of object - oriented programming to the finite element method for linear static analysis . in the view of ooad ( object - oriented analysis and design ) method , a set of basic classes for the fem system are founded and their relationship is discussed too . all these fem classes are implemented in c + + language because the hybrid language c + + is an object - oriented extension of c . ( this language includes all the feature of c and is well suited to solve numerical problems because of its efficiency . )
    本文在靜態(tài)線性有限元系統(tǒng)中引入了面向對象的程序設計方法，介紹了面向對象方法的基本概念及特征，并通過有限元的面向對象分析和設計，確定了一套基本的有限元對象類及有限元的面向對象模型，本文設計的所有類均采用c + +編程語言進行了實現(xiàn)，最終形成了一套fem類庫，它們以動態(tài)連接庫的形式存在。
  5. Important missing aspects are : turbulent flow , numerical discretization techniques specially the relevant and difficult topic of numerical treatment of advection and related numerical methods of solution , variable property fluids , boundary layers , stability , etc . rather , it focuses on more primitive and fundamental issues of numerical treatment of advective equation and proper formulation of initial boundary value ( ib vp ) . numerical problems associated with advective dominated transport include spurious oscillation , numerical dispersion , peak clipping , and grid oriention . however , the key of numerical solution of three - dimensional advective problem is searching for a high - precision interpolating function , which can keep the computational stability and low damping
    3 、針對三維純對流方程提出了實用的擬協(xié)調單元模式，并與線性插值模式和協(xié)調單元模式比較后表明，在物理量大梯度變化的情況下，線性插值模式會產(chǎn)生較大的數(shù)值阻尼，導致解的失真；協(xié)調單元模式具有極高的計算精度和良好的計算穩(wěn)定性，還可較好地克服數(shù)值阻尼，但由于計及物理量的二階導數(shù)項，計算工作量大，邊界條件給定尚存在一定的困難；而擬協(xié)調單元模式不僅具有協(xié)調單元模式計算精度高的優(yōu)點，還避免了物理量的二階導數(shù)項，可大大地減少計算工作量。
