中文摘要：
根据同一被试在锚题上的得分概率向量的模式应该十分相似的直观想法，该文提出了一种新的项目反应理论框架下的等值准则——余弦准则．我们采用GPC模型，利用Monte Carlo模拟方法将余弦准则与Haebara等值准则（Hcrit）glStocking-Lord等值准则（SLcrit）进行比较．研究结果表明，当项目参数估计精度较高或中等而A的取值范围在0．9-2．0之间，新方法往往比Hcrit和SLcrit方法估计的误差小且有显著性差异．
英文摘要：
The probability mass vectors of an examinee who responses to the ancher items in two test forms are intuitively quite approximate. Based on this intuition, a new test equating criterion, known as COSine criterion（COSerit）, is proposed in this paper The COScrit is compared with Haebara equating criterion（Hcrit）and Stocking-Lord equating criterion （SLerit）through Monte Carlo simulation using Generalized Partial Credit Model. The study shows that the results of the new approach sometimes are better than Hcrit and SLerit in terms of the recovery of estimating the equating coefficients and have significant differences when the value of the equating coefficient A is about 0.9 to 2.0.
