参阅有关研究文献和综述,介绍了可变电荷土壤矿物学组成、表面结构特性、电化学性质与扩散双电层理论的一般概念和进展情况,认为从恒电荷向可变电荷的转变是土壤化学发展史上重大的理论突破. With reference to relevant research literature and review, the general concepts and progress of variable charge soil mineralogy, surface texture, electrochemical properties and diffusion double layer theory are introduced. It is considered that the transition from constant charge to variable charge is soil chemistry A major theoretical breakthrough in the history of development.
