摘要
该文通过剖析灰色预测模型ＧＭ（１，１）与指数曲线预测模型ｙ＝ａｅ（ｂｘ）的建模原理，对两者进行了实例比较分析，从中得到了若干启示，两者的差异在于参数估计方式的不同，均仅适用于呈指数规律变化的系统。
By comparison between grey forecasting model GM(1,1) and exponentialcurve forecasting model y-ae(bx)in the model-building principles,several enlightenmentsare obtained by analytical comparison between specific examples。The difference of bothmodels lies in the way of parameter estimation,and both models are applicable only for thesystem which varies in an exponential pattern。
