| 摘 要： | 指出了经典理想气体与热力学第三定律不相容,在低温情况下,应考虑到量子效应的简并性,经典理想气体概念已不再适用.虽然绝对零度不能达到,但可用物理方法无限趋近它,目前的量级已达pK.

| Abstract: | The paper points out that the classical ideal gas is of exclusion with the third law of thermodynamics.At low temperatures it should think of the degenerate state of quantum effect,however,classical concepts is found wanting.Absolute zero can not be reached,but can be very close to it by physical means.In recent years,the order near to it has attained pK. |
