For the study of Brownian motion established kinetic theory of gases played an important role in the process of .1827, Brown observed that pollen suspended in water such as the random motion of material particles .1877 year, Delta claims that the particles The irregular movement of liquid molecules to its collision-induced .1905 imbalance and later years, Einstein, Langevin Smolukhovski, and they were published on the theory of Brownian motion .1908 year, Perrin Experimental observation of the system, confirmed the correctness of the theory.

对于布朗运动的研究在气体动理论建立的过程中起过重要作用。1827年，布朗观察到悬浮在水中的花粉等物质微粒的无规则运动。1877年，德耳索指出，微粒的不规则运动是液体分子对它的不平衡碰撞引起的。1905年及稍后，爱因斯坦、斯莫卢霍夫斯基和朗之万分别发表了他们关于布朗运动的理论。1908年，佩兰的系统实验观察，证实了上述理论的正确性。
