( 4 ) according to the 2 - d advective - dispersive equation of pore medium and combining the result of experiment, the difference between experiment and calculation was located by macroscopical analysis. a new mathematical model suiting to fractured medium was deduced from revised pore medium model. the correction and practicability were verified by the result of experiment
（ 4 ）依照孔隙介質二維溶質對流彌散方程，結合實驗所取得的成果，進行宏觀比較分析，找出實驗與計算的差距，然後對孔隙介質模型作進一步的修正，推導出了適合單裂隙巖體二維溶質運移的數學方程，並通過具體的實驗結果驗證了模型的正確性和實用性。 -
In the numerical solution algorithm, the method of characteristics, analytic method and galerkin finite element method ( galerkin - fem ) can be chosen to solve the advective equation, diffusion equations, reaction ( source / sink ) equations, propagation equations and pressure poisson equation, respectively. the developed new algorithm has been verified using analytical solution of circular conduit flow in a reynolds number range of 100 < re < 1 000 and experimental data of the laminar flow over a backward - step facing step. the flow properties are well characterized by this three - dimensional numerical model
本論文在評述三維粘性流動數學模型已有研究成果的基礎上，著重在數值計算方法的選擇和定解條件的給定對數學模型計算結果的影響進行了研究，並首次提出了求解三維純對流方程的高精度的擬協調單元法，建立了三維低雷諾數re流動的數學模型，並在圓管流動、臺階突擴矩形管道流動中得到驗證和應用。
