| 摘 要： | 本文对互作用为L—J(12—6)势的稀薄量子气体(~4He及~3He气体)进行计算,计算结果表明,在2K以下,费米气体、甚至玻耳兹曼气体都有违反Baierlein猜测的行为。通过计算各散射分波对熵的贡献,本文分析了Baierlein猜测对量子系统不成立的原因以及可能成立的条件。

| Abstract: | The entropy difference between real dilute gss (~3He or ~4He) interacting with L-J (12-6)potentiiai and its corresponding idea gas is calculated. The results show that the Baierlein's conjecture of entropy is violated for Femi gas, even though for Boltzman gas, when the temperature ofthe system below 2K. The contributions to the entropy from each scattering partial wave are calculated.The mechanism of Baierlein's conjecturefor quantum gas is studied in detail. |
