摘要
本文通过试验模拟等量无机外源砷连续多次对土壤的污染，研究土壤对砷的缓冲动力学过程及其特征，确定了其缓冲动力学速率方程为：Ｖ＝ａ·ｅｘｐ（ｈ·Ｔ）ｓｉｎ（ω·Ｔ＋ｑ）＋ｋ·Ｔ＋ｂ本公式为揭示土壤对砷的缓冲容量提供基础。
A series of simulation experiments were conducted to study the successive pollution effects of applied inorganic arsenic on soil by the method of successive application of arsenic at the same rate. Buffering dynamic process of soil to As and its characteristics were studied. A buffering dynamic velocity rate equation was developed.This is thought to be the basis of study on buffering capacity of soil to As.
