布朗运动演示实验的改进

The Improvement in the Experiment Showing Brownian Movement

分析了演示真实布朗运动的实验不易成功的原因,并提出了实验的改进方法:用投影仪胶片来代替盖玻片,从而使观察真实的布朗运动成为一件容易的事情.

This article analyses the difficulies in the experiment showing Brownian movement and it put forward a propasal that the film of overhead projector be used to replace the cover glass.This improvement makes it easier to show Brownian movement.
