摘　　要：比较两样本标准化率须作显著性检验,但两样本间接法标化率比较的显著性检验方法至今未见报道。本文以两间接法标化率之差的标准误计算入手,提出了Z检验及Z^2检验,检验方法及步骤以实例进行说明。In this paper the standard error of the difference between two indirectly standardized rates was discussed and a proposal using Z test or Z-square test to compare two sample indirectly standardized rates was offered. The statistical method was explained using two examples.

关 键 词：间接法标化率 显著性检验 统计
