摘　　要：本文给出测验等值中等组设计、平衡随机组设计和铆测验随机组设计下的线性等值公式的渐近方差，从而得到一般情况下三种设计的线性等值公式的误差估计．同时讨论了与估计精度有关的几个问题．In this paper, asymptotic variances of linear equating were obtained for an equivalent-groups design, a counterbalanced random-groups design, and an anchor- test- random-groups design,and the standard errors of linear equating were estimated under these designs. Some problems associated equating precision were discussed.

关 键 词：线性等值 渐近方差 等值标准误 等值精度
