| 摘要: |
| 本研究在辨析了土壤流动法中动力学参数的传统求算法的一些缺点之后，重新考察了流动法的特征，在此基础上提出了一种先通过数值微分－－五点三次多项式－－求算出反应速率之后，再依据反应速率求算动力学参数的方法，并动用该法求算了潮土对钾离子的吸咐、解吸咐动力学参数。结果说明该法具有很好的可靠性。 |

| Abstract: |
| Some shortcoming of the traditional method for solving the parameters in soil kinetic study with displacement techniques was reviewed, and the characteristics of displacement techniques were evaluated. A numerical differential method was brought forward , in which the reaction velocity can been calculated with five dot cubic polynomial. The application of this method demonstrated that it was quite reliable in solving the kinetic parameters of soil potassium adsorption and desorption. |
