论文摘要
我们表明，理想流体的Lagrangian等于（在其定义上和公制的选定签名符号）等于流体的总能量密度，即休息能密度加上内部能量密度。
We show that the matter Lagrangian of an ideal fluid equals (up to a sign -depending on its definition and on the chosen signature of the metric) the total energy density of the fluid, i.e. rest energy density plus internal energy density.
