能斯脱定理向负温度区的推广——关于lim(△S)_T=0的论证

Generalization of Nerst Theorem to Negative Temperature-Verification of lim T→-0 (△S)_T=0 Applied Physics Depantment

本文根据负温度下的热力学及统计理论,论证了lim T→-0 Cx=0仍然成立,并由此式及负温度下的热力学第三定律论证了lim T→-0 (ΔS)_T=0同样成立.指出了如果lim T→-0 C_x→C_x^0(常数),则负温度下的热力学第三定律是不独立的,并可由负温度下的热力学第二定律导出.

In this article. lim Cx=0 is obtained on thermodynamics and statistical physics in the negative temper-ature. From this formula and the third law of thermodynamicsin negative temperature, lim,(△S)T=0 is deduced.Furthermore.it is pointed out that if lim,Cx→C_?~O (a constant), then the thirdlaw of thermodynamics is not independent, and it can be deducedfrom the second law of thermodynamics in negative temper ature.
