摘要
本文就实际观测中的不等时距情况进行了讨论，经过变换，将等时距的GM（1，1）模型，转为不等时距的GM（1,1）模型，进行预测．并经过残差修正，提高预测精度．
In this peper, the inequality time-distance in reality obovation had beentransformed. The equality time-distance GM (1, 1) model was transformed into inequatily time-distance GM (1 ,1) model to predict, and predicted accuracy was improred by residue correct.
