Equation of state of a partially homogenized plasma of low-dense porous matter

The equation of state (EOS) a low-density porous substance plasma is proposed in the form continuous media EOS containing, as pressure control parameter, degree homogenization, which function initial structure, well current values density and temperature. Using partially-homogenized-plasma an approximate analytical solution found numerical calculations were performed problem thermal expansion flat layer matter. features obtained results are discussed comparison with case equivalent chemical composition. used to analyze experimental data on heating laser X-ray pulses.
