从基于三个标量场的作用量原理出发,给出了无任何约束的相对论性理想流体的哈密顿公式。我们发现它不仅可以描述正压情况,而且可以描述更一般的理想流体的熵和两个或两个以上的热力学变量守恒沿着流体流动(即多组分理想流体)。
We give a Hamiltonian formulation of relativistic perfect fluids free of any constraints starting from an action principle based on three scalar fields. We show that it can describe not only the barytropic case but also more general perfect fluids with entropy and two or more thermodynamic variables conserved along the fluid flow (i.e. multiconstituent perfect fluids).
