论文摘要
重新审视了超流体的热力学,澄清了两个点。首先,获得给定平衡速度的密度和压力分布,发现反热电流会导致压力抑郁和中心力。其次,结果表明,理想的两流体水力\ dymanics只是\ textit {equilibrium条件}的组件 - 熵的表达式最大。
Thermodynamics of superfluids is revisited, clarifying two points. First, the density and pressure distribution for given equilibrium velocities is obtained, with the finding that counter heat currents give rise to a pressure depression and a centripetal force. Second, it is shown that the ideal two-fluid hydro\-dynamics is simply an assembly of \textit{equilibrium conditions} -- expressions of entropy being maximal.
