摘　　要：通过论证灰色关联分析中分辨系数对灰色关联系数的影响,指出了选取分辨系数时应明确的几个结论,将通常见诸于灰色关联分析文献中取分辨系数ρ=0 5改进为ρ=0 05,以提高灰色关联分析的分辨率。Through demonstrating the influence of discrimination coefficient on grey incidence coefficient in the grey incidence analysis,this paper presents some conclusions defined in selecting discrimination coefficient and the improvement in selecting discrimination coefficient and the improvement in selecting the discrimination coefficient in usual grey incidence analysis literature which is changed from ρ =0.5 to ρ=0.05,thus the rate of discrimination is improved
