摘　　要：讨论了用Possion定理、局部极限定理和积分极限定理近似计算二项分布概率时的误差,对这3种近似计算的误差进行了比较,详细分析了用局部极限定理做近似计算时的误差。This paper discusses the errors of the approximate calculations of binomial distribution probability by using the Possion theorem, the local limit theorem and integral limit theorem respectively, makes comparison of the errors of the three approximate calculations, and analyzes in detail the error of the approximate calculation with partial limit theorem.
