摘要
本文从分辨系数对关联系数的影响出发，指出灰色关联分析中，应先建立分辨标准，然后再确定分辨系数ρ的取值。并用一实例讨论了ρ的选取方法，说明了在一些情况下取ρ＞０．５更符合实际情况。
To begin with the influence of a resolution factor on an interaction factor, the paper pointed out that the resolution standard should be first established, and then the value of the resolution factor P can be determined. An example denoting the actual facts is used to discuss the method of the P selection, showing that the selection of P>0.5 is much in compliance with the actual circumstance to some cases.
