布朗运动是证明分子热运动的重要实验.在显微镜下观察悬浮在液体中的小颗粒,可以看到这些颗粒都在不停地做无规则运动.如果把视线集中在任意一个颗粒上,就可以发现它好像不停地做短促的跳跃,方向不断改变,毫无规则,就像一个“醉鬼”在毫无目的地乱溜达.当然这个实验做起来并不 Brownian motion is an important experiment to prove the molecular thermal motion.If we observe small particles suspended in the liquid under the microscope, we can see that these particles are constantly moving irregularly.If we focus on any particle, we can I found it as if I kept jumping short, the direction changed, there was no rules, it was like a “drunkard” wandering aimlessly for no apparent purpose. Of course, this experiment was not done
