      In the equation of state given in the paper, pressure and energy are represented by a sum of the potential component and thermal components of nuclei and electrons. The Grueneisen grid factor is described by the density function, its analog for electrons is a constant quantity. The heat capacity of nuclei is a constant quantity, the heat capacity of electrons is a linear function of temperature. The EOS values of parameters are given for molybdenum, iron, lead, copper, aluminum, and tungsten; the calculated and experimental results are compared.
