应用电导率法，通过大型移流弥散砂槽模型试验，成功地测到了混合带，并对混合带及其动态特性进行了观测、分析和研究，在总体水头的水平梯度方向与浓度的水平梯度方向（弥散的反方向）相反的条件下，得到了咸水入侵进慢退快、混合带发展演化过程中有回咸现象以及介质分层、高浓度等试验的部分规律。部分成果对滨海地区水资源的规划、管理和海（咸）水入侵的预防、治理以及移流弥散问题的物理模型、数学模型的研究有参考意义和实际应用价值。
Using conductivity method, the mixed belt was successfully measured through the model test of large displacement dispersion sand tank. The mixed belt and its dynamic characteristics were observed, analyzed and studied. The horizontal gradient direction and the horizontal gradient direction (The opposite direction of dispersion), we get some laws of slow-moving saltwater intrusion, returning salinity during the development and evolution of the mixing belt, and experiments of medium stratification and high concentration. Some results have reference significance and practical application value to the research on the water resources planning and management in coastal areas, the prevention and treatment of water intrusion (sea) and the physical model and mathematical model of migration and dispersion.
