摘要
灰色理论之GM（1,1）模型能对原有变形测量值进行较好的处理,但对于少量数据情况下的观测物形变规律预测并不是很理想。重新对平射中的亲和系数进行调整从而产生非均衡白化值,即对原始数列生成新数列时所占的权重进行了探讨,给出自由权重的生成公式,以求模型所产生的变形值更接近实际的变形规律。
Abstract
The GM（1,1） model in the Grey Theory can make a good deal with original deformation measured datas,but it can not deal well with observed objects deformation law prediction with few data.A re-adjustment to affinity coefficient in flat fire was made,and then the unbalanced explicit value was got.Weight of original data series to new data series was discussed.In order to much closer to the deformation values produced by practice deformation law,generated formula of free weights was given.
