  1. Then a one - dimensional unsteady incompressible flow with moving pollutant source model was proposed. the continuity equation, momentum equation and convection - diffusion equation were discredited using finite volume scheme. thus a software for predicting the air velocity and pollutant in railway double track tunnels was developed

    接著，根據雙線鐵路隧道運營通風的特點，建立了一維不可壓縮非恆定流和流動污染源的物理模型以及山相應的連續性方程、動量方程和對流擴散方程構成的數學模型；在此基礎上，利用數值計算方法，編制了一套雙線鐵路隧道運營通風的數值計算程序。
  2. Influence of some parameters are analyzed, such as : d ( diffusion rates ), v ( coefficient of convection ). double or three compartments model of soc is used. it is found that the diffusion process for different compartments of organic carbon in soil is very differently. this model could also calculated the accumulation of soc in soil per year, which is helpful to understand the dynamic process of organic carbon storage in soil

    最後一章本論文對新老有機碳在土壤當中的遷移積累進行了數值模擬，分析了不同參數對有機碳擴散的影響，得到了不同年齡的有機碳在土壤中的分佈規律，這為進一步預估中國土壤中的有機碳動態變化打下了基礎。
