摘　　要：目前,介绍6σ管理的一些文献给出的σ值和DPMO值转换表可谓五花八门,反映出人们对此问题认识上的不统一,甚至存在一定偏差。因此,有必要从理论上探讨σ值和DPMO值之间的转换关系,并以此为依据对现有的σ值和DPMO值转换表进行修正。Presently, different literatures dealing with 66 management give different kinds of transformation table from σ to DPMO. That reflects the bias lying in the transformation process. As a result, it is necessary to make it clear the theory that explains the relationship between the values of σ and DPMO. Table 2 in this paper is based on the theory, and apparently it is an adjusted one for the existing tables.
