摘要
介绍了布朗运动仿真实验的设计与实现方法,利用"位置朗之万方程"的数值离散化,最大程度还原真实的布朗运动.通过对仿真实验数据的定量分析,并计算出了阿伏加德罗常量的近似值.
The design and implement method of Brownian motion simulation experiment were in-troduced .The characteristics of real Brownian motion was maximally retained by the numerial discret-ization of position of Langevin equation .By quantitative analyzing of the motion traces ,a close ap-proximation of Avogadro constant was obtained .
