In recent decades, a fundamentally new direction of scientific work has emerged in the field of natural sciences related to the study of the effects on a substance of such physical factors as radiation, electromagnetic radiation, ultrasound, plasma, high pressure, cosmic vacuum, gravity, etc., where the general criterion of extremity impact can be the occurrence of intermediate highly active states of particles of a substance, which ultimately leads to a qualitative change in the micro- and macrocharacteristics of the object being processed, new properties. One of the types of complex extreme effects is the effect of high-voltage electric discharge, which combines the simultaneous impact of strong mechanical compression, high-power ultrasound, hard X-ray, UV and IR radiation on a substance. Electromagnetic fields formed in the discharge process also have a strong influence on both the discharge itself and the ionic processes in the surrounding liquid. Under their influence various physical changes and chemical reactions occur in the material being processed.
