Today, his formula for entropy S is famous: S = klnΩ K is the Boltzmann constant andΩ is the number of possible microscopic states which give the same thermodynamical state that a system may be in.

在论文中，他利用原子运动轨道闭合的假设，将熵的表示与力学的最小作用原理直接联系起来，试图从纯力学的角度证明热力学第二定律。

Assumes that molecules are rigid ball, intermolecular End X are all elastic collision, in addition to the instant of collision, the molecular force can be ignored, then the chemical pure gas, K = 4nd2πkT = 4d2pπ, where: k for XmSkTSm Boltzmann constant, m is molecular weight, d the molecular diameter, n the molecular number density, p the gas pressure, T is thermodynamic temperature.

假定分子是刚性球，分子间完X全是弹性碰撞，除了碰撞瞬间外，分子力可以忽略，那么在化学纯的气体中，K＝4nd2πkT＝4d2pπ，式中：k为XmSkTSm玻耳兹曼常量，m为分子质量，d为分子直径，n为分子数密度，p为气体压强，T为热力学温度。
