摘要
文中对描述一维、稳定渗流与连续定浓度注入示踪剂的砂柱弥散试验的近似解析解进行反函数变换 ,建立了在多孔介质与示踪剂间为均衡吸附条件下 ,能够计算多孔介质纵向弥散度与阻滞系数的方法。而且 ,这种方法在介质的有效孔隙率为已知的情况下 。
A method to calculate the longitudinal dispersity and retardation factor of porous medium is set up herein by transformation of the approximate analytic solution describing one dimension,steady seepage and continuous injection of tracer with constant concentration under the condition of equilibrium adsorption between porous medium and tracer.The said method can also be used to calculate the adsorption factor to tracer by porous medium if the effective porosity of the medium is known.
