农药降解的GM（1,1）模型

The GM(1,1) Model of Pesticide Degradation

重点介绍了一种农药降解的ＧＭ（１，１）模型，实你分析表明，ＧＭ（１，１）模型的预测精度高于经典的指数函数模型。

The GM(1,1) model of pesticide degradation was expounded.It is indicated that the forecasting precision of GM(1,1) model was higher than that of the exponenfial function model from real examples analysis.
