弯曲时空中的热平衡

Thermal equilibrium in curved space-time

讨论了弯曲时空的一种特殊情况——稳态时空中的热平衡条件,利用普朗克黑体辐射定律和广义相对论,得出了两系统通过辐射而达到热平衡时坐标温度相等,但固有温度不相等的结论.

The condition for thermal equilibrium in stationary space-time,which is a special case of curved space-times,is discussed.Using the Planck＇s theorem of blackbody radiation and principles of general relativity,we conclude two systems that have reached thermal equilibrium through thermal radiation have the same coordinate temperature but generally different proper temperature.
