摘要
若一种化学纯的多原子分子气体处于一封闭容器中 ,受到某一频率的光照射而离解为分子碎片 ,则不难想象 ,此封闭容器中的压力将发生变化 从统计力学原理出发 ,导出了压力随时间变化呈现的规律 。
When the gas of the chemistry-pure polyatomic molecular is in a closed container and is dissociated into photofragments by the irradiation of the light of the special frequency,we can imagine easily that the pressure in the closed container will change.In this paper,from statistical principle,we have carefully deduced the law of the change between pressure and time,which will play a positive role in exploring the interaction law of light and matter.
