摘　　要：在某些教育测量中,不仅要求在合格与不合格分界处有一个误差小、鉴别力强的划界分数,同时还希望在优与非优分界处有另一个误差小、鉴别力强的划界分数,这就要求把测验信息函数的目标状态设计成双峰曲线.本文以项目反应理论为指导,就双峰曲线划界分点的确定及相应测验项目选择问题进行了解析论证,并给出了算法设计流程.In certain education survey, it is required requests to have an error with the unqualified dividing line place to be small qualified, the distinction ability strong marks off the score, and also it has another error with the non-superior dividing line place to be small superiorly, the distinction ability strong marks off the score. So the examination information function problem status should be designed as the bimodal curve. Taking the project response theory as the instruction, marked off the precession of equinoxes on the bimodal curve definite and the corresponding examination project choice question were anlyzed and the algorithm design flow was given.
