The two-dimensional hydrodynamic behavior of an X-ray laser plasma on a slab under non-equilibrium conditions is studied in a novel way combining numerical calculations with analytical results from a one-dimensional similar equation. Changes of both electron density and temperature with time were studied. It is found that the inhomogeneity of temperature along the z-direction due to the non-uniformity of the foci line can be relaxed by the hydrodynamic behavior and usually this process takes more than 1 ns to become uniform, while the density distribution takes several hundred picoseconds. As a result of the inhomogeneity hydrodynamic oscillation of the plasma in the z-direction was obtained.
