有限体积物体的协变热力学
Covariant Thermodynamics of an Object with Finite Volume
摘要：
提出了一种定义有限物体相对论熵的协变方法。有限体积物体的能量-动量不是协变的物理实体，这是由于体积的同时性的相对性。介绍了一种正确处理这种情况的方法，并将其应用于熵的计算。结果与van Kampen-Israel理论一起给出了简单的自洽相对论热力学。
英文摘要：
A covariant way to define the relativistic entropy of a finite object has been proposed. The energy-momentum of an object with finite volume is not a covariant physical entity because of the relativity of simultaneity. A way to correctly handle this situation is introduced and applied to the calculation of entropy. The result together with van Kampen-Israel theory gives simple and self-consistent relativistic thermodynamics.
