| 摘 要： | 一般认为质量相同、温度不同的同种气体有相同的分子数,则它们混合后,达到热平衡的温度为原来温度之和的一半.然而,根据狭义相对论,可以得出质量相同、温度不同的同种气体含有不同数目的分子,进而可以推出对于质量相同、温度分别为T1、T2的同种气体混合后,达到热平衡的温度不等于T1与T2之和的一半.

| Abstract: | It is generally believed that the same kind of gases with equal masses and different temperature must have common number of molecules, and the temperature in thermal equilibrium after they are mixed together would be the half of the sum of their original temperatures. However, according to special relativity, the same kind of gases with equal masses and different temperatures should have different number of molecules. Further, the temperature of themal equilibrium , after they are mixed together, would not equal half of the sum of their original temperatures. |
