Abstract
The new experimental results that allow to execute stabilized critical discharges between metallic granules in a liquid by combination of electrotechnical parameters of discharge contour are obtained. The form of channel and law of its extension, taking to consideration the momentary electrical power, were de- termined. This has allowed to offer dependences for regulation of an affective volume of discharged plasma. Different diameter gas inclusions influence on the processes of formation and development of discharge were estimated.
