土壤表面电荷磁致效应的研究

本文主要研究了棕壤和盐土磁处理后，比表面、表面各类电荷及电荷密度的变化，以及磁场强度和土壤湿度对上述磁致效应的影响。研究发现，磁处理可显著降低土壤比表面值；增加土壤可变负电荷和电荷密度以及减少可变正电荷数量。这些结果为应用磁改良技术改善土壤微结构及其功能提供了一定依据

Effects of Magnetic Treatment on Surface Charges of Soil

The present paper mainly deals with the changes of specific surface area, various kinds of surface charges and charge density of brown earth and saline soil after they are treated in the mognetic field. At the same time, the influences of magnetic field intensity and soil humidity on the above magnetic effects of soils are also investigated. As the results show, magnetic treatment can significantly reduce the specific surface area of two kinds of soil. In contrast, the Variable negative charges and change density of these soils increase considerably, while the variable positive charges decreases. In a word, all the above results provide useful basis for the utilization of magnetic technique in the improving the soil microstructure and its function.
