Abstract:

The development of every sort of physical process in matter is in the last analysis always deter mined by a change in energy density. Thus an uninterrupted increase in the energy reserve in a definite quantity of a solid phase gives rise to new structural transformations after a certain critical value has been attained, and also alters the aggregate state. These changes are usually related to some form or another of phase transformations. Any such transformations result either from the immediate action of heat without, increasing the thermal energy of motion in each volumetric unit, or from the initial accumulation in a given volumetric unit of a reserve of poten tial energy under the effect of external forces. When a certain critical value of energy density has been reached in some volumetric unit there begins the transformation of potential energy into other forms accompanied by the appearance of a new phase and also by the ineluctable trans formation of a portion of the potential energy into energy of disordered thermal motion. In the case of disruptive discharge of a dielectric the role of this new phase will be played by the positive and negative carriers of the charge resulting from the particles attaining the critical energy value necessary for a particle to pass over from the initial state into that of ionization.
