查询词典 retardarce

The expression of one-dimensional mathematical model of vertical migration of ammonia in the CRI system is:The parameters in the CRI model are determined as following: the retardarce coefficient is determined by static isothermal absorption experiment, the velocity of sewage travel through the soil column is determined by permeability test, the vertical dispersion coefficient is determined by test the electric conductivity of tracer in the dispersion experiment, the rate of nitrification and denitrification is determined by test of Baps technology.

依据单一氨氮、硝氮配水条件下的试验结果，引入多孔介质的溶质运移理论及对流-弥散方程，考虑NH4+-N在CRI系统中的运移受到对流和水动力弥散作用的影响，并吸附-解吸、硝化与反硝化3个过程，首次将配水流经CRI土柱的孔隙水流速方程与CRI土柱内发生的、以氧为约束条件的硝化、反硝化过程联系起来，建立了CRI系统一维垂向氨氮运移转化数学模型，表达式为：研究分别通过静态等温吸附实验率定了模型方程中的阻滞系数、通过渗滤试验测定了土柱中的孔隙水流速、通过测定弥散试验中示踪剂的电导率确定了纵向弥散系数、通过气压过程分离技术测定了土柱中的总硝化与反硝化反应速率常数，最后通过测定土柱沿程氧化-还原电位的方法分析氨氮在CRI系统中的运移转化机理。
