摘　　要：本文运用正态分布的概率密度函数与标准正态分布的概率密度函数的相互代换原理,制定出符合体育评价规律的体育考核标准数学模型,并举例计算出优、良、中、及格、不及格等五个等级的数学模型分别为:x优=1.04S+珚X;x良=0.13S+x珋;x中=-1.04S+x珋;x及=-1.65S+x珋;x不及﹤-1.65S+x珋。In this paper, the application of normal distribution probability density function with standard normal distribution probability density function of mutual substitution principle, developed in line with the sports evalua- tion rule of physical examination standard mathematical model, and an example is calculated and, good, pass, fail, five grade math model respectively： Actor = 1.04S ＋ x;Good =0.13S ＋ x;Medium = - 1.04S ＋ x;Pass = - 1.65S ＋ x;Unqualified 〈 - 1.65S ＋ X.
