摘要
讨论了相对论热力学中流体系统的压强与温度的变换。通过在实验室参考系引入引导力,消除了目前文献中受热常速流体的内涵压强与外延压强之间的矛盾。结果表明:流体系统压强的两种相对论属性完全一致,都是Lorentz标量。并且进一步分析了引导功与热量的关系,指出功热关系的不同界定标准将给出温度变换的相反结果;Planck热力学与Ott热力学之间差异的焦点就在于是否确认引导功。最后重新计算了Landsberg佯谬中的理想实验,得出传统的功热界定标准必然导致运动温度收缩的结论。
The transformation about pressure and temperature of fluid system in relativistic thermodynamics is discussed. By calling introducing force into the laboratory reference system, the contradiction in present literature between extension pressure and intension pressure has been eliminated. The obtained result is that two kinds of relativistic attribute about pressure of fluid system is consistent completely and are totally Lorentz scalar quantity. The relation between introducing work and heat is further analyzed. The result shows: different definition criterion of relation between work and heat will give out opposite result in relativistic temperature transformation, the focus of difference between Planck school and Ott school is whether the introducing work is acknowledged. At the last of this paper the ideal test in Landsberg temperature paradox is completely recounted, concluding that the classical definition criterion of relation between work and heat will surely lead to the contraction of motion temperature.
