摘要
以高等学校入学考试的考生实测数据，研究项目反应理论中数学模型的应用、数学模型的拟合性统计检验，并研究了模型与样本容量、模型参数估计与样本容量的关系，得到一些有意义的结论。
The study focused on the selections to mathematical models of item response theory, and fitting tests of mathematical models. relations between the sample size and item reponse models, and relations between the sample size and pararnaters estimation of item response models. All the data the study adopted came from the National College Entrance Examination. The study has come to some significant conclusions.
