摘　　要：运用狭义相对论理论和已确定的温度(T)的相对论结果分析了热力学理论中的若干常用概念,并得出了相应的动力学结论:理想气体热力学系统的压强(P)和内能(E)均与惯性运动无关,而熵(S)与惯性运动有关,且熵是增加的。The paper has analysed several basic concepts of thermodynamic theory with both relativity theory and conclusions which has been derived, and turmed out correspond dynamic consequence. It derived that both pressure and internal energy of thermodynamic system of ideal gas are all not correlative with intertia motion, but the entropy is correlative with intertia motion, and then it is increasing.

关 键 词：惯性运动 温度 压强 内能 熵 热力学 相对论
