counter tube hysteresis

The dispersion coefficient, dispersivity and lag coefficients of manganese movement in aquifers are decided by earth experiment.

利用土柱实验确定锰在含水层迁移的弥散系数、弥散度和滞后系数,建立了锰在含水层中迁移的一维模型,并给出解析解。

That means in the porous media,the thinner the grain is,the stronger the adsorption ability of the iron is,so that the iron transport lag coefficient is big and the.

结果表明:天津市7类多孔介质对铁的吸附均符合Langmuir吸附模式;多孔介质颗粒越细,吸附铁的能力较强,铁迁移滞后系数越大,迁移性越差,颗粒较粗,吸附铁的能力较差,铁迁移滞后系数越小,迁移性越好;在多孔介质中,铁随地下水流动的迁移能力极差。
