  We offer a metal model suitable for the description of fast electrophysical
processes in conductors under influence of powerful electronic and laser
radiation of femto- and picosecond duration, and also high-voltage
electromagnetic pulses with picosecond front and duration less than 1 ns. The
obtained dynamic equations for metal in approximation of one quasineutral
liquid are in agreement with the equations received by other authors formerly.
New wide-range expressions for the electronic conduction in strong
electromagnetic fields are obtained and analyzed.
