摘　　要：考虑学生入学差异提出了加权均分模型,通过比较加权均分模型与正态分布模型的数学特征,证明了两模型内在的一致性,但加权均分模型计算方法简单,表现形式直观。根据某高校专业课程成绩对两者进行实证分析,研究结果表明不同专业、不同学期及不同课程设置方式下,该模型与正态分布模型在反映绝大部分学生(68.28%)成绩方面有很好的一致性。This paper proposes a weighted average model to analyze the regional differences of enrollment results. The similarities and differences of mathematical characteristics between the weighted average mod el and the normal distribution model are compared, which proves the inherent consistency of the two mod els, but the calculation method of weighted average model is simple and the form of expression is intu-itionistic. Empirical analysis results show that this model has a good agreement with normal distribution model with a vast majority of students (68.28%) among different majors, different term and different cur riculum mode.
