负绝对温度及温标

Negative absolute temperature and temperature scale

从热力学角度分析了负绝对温度,讨论了绝对温度与内能的函数关系,指出了绝对温度的不方便之处,引进了约化温度T,以约化温度来标度热力学温标并且讨论了约化温度与内能之间的函数关系.指出约化温度是随着内能的增加而单调地增加的连续函数.

From thermodynamic point of view the negative absolute temperature were analyzed. The functional relation between absolute temperature and internal energy was discussed and show the disadvantage of the absolute temperature. Introduced reduced temperature function ,and the thermodynamic temperature scale reordered by reduced temperature. By discussed the functional relation between reduced temperature scale reorclered by reduced temperature. By discussed the functional relation between reduced temperature and internal energy, show that the reduced temperature is a continuously monotonically increasing function of internal energy as the internal energy increasing.
