| 本文综述了土壤多孔介质中胶体迁移的释放与沉积机制、影响胶体迁移的多种因素以及土壤中胶体与各种污染物的协同迁移作用，总结了模拟胶体迁移的数学模型以及计算机软件的应用。研究表明，胶体在土壤中的迁移主要受应变、附着、薄膜应变等迁移机制的影响，多孔介质的性质、流体的性质以及胶体自身的性质也会影响胶体的迁移。此外，胶体能有效吸附地下水多孔介质中的有机或无机污染物，并对其在地下环境中的迁移产生显著影响。目前已有许多学者通过数学模型来模拟胶体在土壤中的迁移过程，而计算机技术的进步也将促进更加先进的软件模型应用到胶体迁移的模拟中。 |
| 英文摘要: |
| This paper summarizes the release and deposition mechanism of colloidal transport in soil porous media, the factors affecting colloidal transport, and the synergistic transport of colloidal and various pollutants in soil, and summarizes the mathematical model for simulating colloidal transport and the application of computer software. The study shows that the migration of colloids in soil is mainly affected by the mechanisms of adsorption desorption, strain, blocking and ripening. In addition, the properties of porous media, fluid and colloids themselves will also affect the migration of colloids. At present, many scholars have simulated the colloidal transport process in soil through mathematical models, and the progress of computer technology will also promote the application of more advanced software models to the simulation of colloidal transport |
