关于“第二维里系数方程”的几点评论

Some comments on `Equation for the second virial coefficient`

I. H. Umirzakov

摘要:

使用Kaplun A.B.的论文中建议的公式计算的第二病毒系数,Meshalkin A.B.本文将高温高压1999年第31卷第253-258页上发表的第二维里系数公式与氦、氢、氖、氩、氪、氙、二氧化碳、水、氨、甲烷、乙烯的实验数据进行了比较。结果表明,在实验误差范围内,该公式不能描述上述物质的第二维里系数与实验数据的温度关系。后者与上述论文的推导存在争议。计算结果还表明,对于氦、氢、氖、氩、氪和甲烷,在不确定度范围内,该公式不能描述推荐的第二维里系数。

英文摘要:

The second viral coefficient calculated using the equation suggested in the paper of Kaplun A.B., Meshalkin A.B. Equation for the second virial coefficient published in High temperature high pressure, 1999, Volume 31, pages 253-258 is compared with experimental data for helium, hydrogen, neon, argon, krypton, xenon, carbon dioxide, water, ammonia, methane, ethylene. It is shown the formula cannot describe the temperature dependence of the experimental data on the second virial coefficient for the all above substances within the experimental error over the investigated temperature interval. The latter is in controversy with the derivations of the paper mentioned above. It is also shown the formula cannot describe the recommended data for the second virial coefficient within their uncertainties for helium, hydrogen, neon, argon, krypton and methane.
