本文较全面地介绍同一时点（横向）生命质量资料分析的TOPSIS法,将其推广于组间比较并对有关问题进行讨论。对两戒毒组生命质量进行的TOPSIS分析表明:两戒毒组生命质量在刚入戒毒所时总的看来无统计学差异。
This article more comprehensively introduces the TOPSIS method for the analysis of the quality of life at the same time (horizontal), and generalizes it to groups and discusses related issues. The TOPSIS analysis of the quality of life of the two detoxification groups showed that there was no statistical difference in the quality of life of the two detoxification groups when they first entered detoxification facilities.
