  6. In this paper a numerical method for equations of transport and biodegradation in the fractured media is discussed. because the equations consist of terms related to advection, diffusion, biochemical as well as the term of exchange betwen the fracture and the porous media, it is very difficult to find their solution. in order to find more efficient method for solving these equations, several numerical methods for the equations without biochemical terms are discussed first. the numerical results show that the cubic spline method can be used to solve advection flow dominated problem which often occurred in the fractured media. then, the equation with both advection - diffusion term and biochemical term are discussed. the splitting - operator is used to decouple the advection and diffusion terms with biochemical term in the equations. the way to determine the smaller time step for solving fast biochemical terms is introduced through comparing the order of characteristic time of biochemical term with that advection ( diffusion ) term. numerical simulation results show that good agreement between analytical solution and experiment result is attained

    本文討論了含隙介質地下水污染物輸運與生物降解非線性方程組數值求解方法.方程含有對流項、擴項、生長、死亡、吸附、解吸、趨化和孔隙與隙介質界面間的交換項的非線性偶合,使演算法十分困難.本文討論了無生化過程時的幾種求解方法,數值結果表明:用三次迎風插值法對常見的對流項占優勢,且場變量有較大梯度的問題較適用.在討論有生化過程時,利用對流項與生化項的特徵時間量級估算,給出了求生化過程作用子步的時間步長估算辦法.用上述方法所得到的模擬結果與解析解、無化學和有化學的實測值對比,吻合很好
