【摘要】 本文对双重多孔介质中溶质运移的团粒扩散模型(Ⅰ)、团粒扩散和膜交换模型(Ⅱ)、一阶动力模型(Ⅲ)和对流-弥散模型(Ⅳ),应用时间动量分析方法,研究了溶质运移的平均时间、有效弥散系数、诱发弥散系数和质量交换系数的结构及其影响因素。更多还原

【Abstract】 In this paper four models are proposed to represent solute transport in aggregated soils. The time moment method is used for the analysis of the effects of model parameters on average breakthrough time, bulk velocity, effective dispersion coefficient, induced dispersion coefficient and mass transfer coefficient.更多还原
