非广延统计中广义双原子和多原子气体的Heat capacity

Heat capacity of the generalized two-atom and many-atom gas in nonextensive statistics

Lina Guo, Jiulin Du

摘要:

本文用Tsallis统计中的广义双原子理想气体模型对实际气体进行了统计描述。通过对N_2、O_2和CO等双原子分子气体的热容与实验结果的比较,我们发现这些气体在常温下表现为广延的,但在低温下可能是非广延的。此外,我们还研究了广义多原子气体模型的热容。我们得出结论,对于高自由度的多原子气体,弱的1-q<0的非延拓性可以导致不稳定性。

英文摘要:

We have used the generalized two-atom ideal gas model in Tsallis statistics for the statistical description of a real gas. By comparing the heat capacity with the experimental results for the two-atom molecule gases such as N2, O2 and CO, we find that these gases appear extensive at normal temperature, but they may be nonextensive at the lower temperature. Furthermore, we study the heat capacity of the generalized many-atom gas model. We conclude that, for the many-atom gas with a high degree of freedom, a weak nonextensivity of 1-q<0 can lead to the instability.
