【 摘 要 】

Density dependence of the dielectric permittivity for water was obtained using the molecular dynamics method for the supercritical region at T = 670 K in a broad range of density, and for T = 300 K and T = 350 K near the coexistence curve. Critical values of the electric field strength which make possible the spinodal decay "liquid-vapor" were calculated.
