| Abstract: | Knowledge of nutrient and pollutant ions transport is important from an agricultural and an environmental point of view. With the developing of various kinds of model. The determination of transport parameter became the key problem remained. This article summarizes methods of determination of transport parameter from BTC: Trail and Error,Slope Method, Statistic Property Method, the Least-squares Inversion Method, Graphic Method. Holdup Method. Moment Method. |
