摘　　要：本文对抛硬币实验的模拟进行研究。利用计算工具的高效和算法的合理性,给出模拟抛硬币实验的方法,分别在Casio fx-991ESPLUS科学计算器、Microsoft Visual C++6.0以及MATLAB R2012a三种环境下进行数据的获取和总结,并优化了随机数的生成方法,验证了抛硬币正反面朝上概率相同的结论。该模拟方法不仅适用于概率论教学过程中的演示,也可为历史上其他相关数学实验的模拟和验证提供思路。This paper researches on simulation of coin tossing experiment. Considering highefficiency and logical arithmetic of calculating facilities, we simulate the experiments based on the environment of Casio fx- 991ES PLUS scientific calculator, Microsoft Visual C＋＋ 6.0 and MATLAB R2Ol2a. During the simulation, method of acquiring random number is optimized in order to make it more reasonable to draw the convictive conclusion that the probability of head or tow during a coin tossing is equal. These methods of simulation are not only fit for presenting in Probability Theory teaching, but can also provide thoughts on simulation and verification of relating mathematical experiments in history.
