【摘要】 对根据分子间相互作用的刚球排斥势模型和Lennerd-Jonse势模型分别导出的第二维里系数和与VanderWaals方程对应的展开系数进行了数值模拟,并将模拟结果进行了比较。结果表明,Lennerd-Jonse势模型能较精确地反映分子的相互作用,导出的物态方程与实验更符合。更多还原

【Abstract】 The second Virial coefficient and modifier factors corresponding to Vandor Vaals equation are simulated which are deduced respectively with rigid-sphere model and Lennard-Jones model. The simulation results are compared ,the results show that the interaction between molecules can be accurately reflected with Lennerd-Jones model,while the state equation deduced is more consistent with experiment.更多还原
