摘要: 求出了任意维经典非理想气体的硬心势、方阱势和Lennard-Jones势的第二位力系数,并给出了计算更高位力系数的方法与途径.结果表明:对于Lennard-Jones势,只有当维数n〈6时,第二位力系数才收敛.

Abstract: The 2nd virial coefficient of the hard sphere potential, rectangular potential well and LennardJones' potential are obtained for classical non-ideal gases in any dimension. The method of calculating higher virial coefficient is given. It is explicated that the 2nd virial coefficient converges for Lennard-Jones' potential, when the dimension n is smaller than 6.

Key words: any dimension, non-ideal gas, virial coefficient, statistical thermodynamics
