标题： Hydrodynamic approach to the Synge gas

摘要： 描述单原子相对论Synge气体能量演化的完美能量张量的必要且充分条件得以获得。 然后，可以构建一个类似Rainich的爱因斯坦-Synge解理论。 从流体力学的观点分析了在低温或高温下，或者在整个适用范围内近似于Synge气体状态方程的方程。 显示英文摘要

摘要： The necessary and sufficient conditions for a perfect energy tensor to describe the energy evolutions of a monoatomic relativistic Synge gas are obtained. Then, a Rainich-like theory for the Einstein-Synge solutions can be constructed. Equations of state approximating that of a Synge gas at low or at high temperatures, or in the entire domain of applicability, are analyzed from a hydrodynamic point of view.
