摘要：
Many physical and chemical processes are observed in water under the formation of high voltage discharges, which depend on the characteristic of the system for generation of high voltage discharge pulses and the physical properties of the liquid medium. Considering the dynamics of these processes, the determination of the electrical parameters of the water is necessary for the practical usage of the electrical discharges in water in different technological applications. The aim of the present paper is to analyze experimental data for the water resistance change during the formation of a high-voltage discharge pulse regarding the influence of some electrical parameters of the system and the water temperature. A complex mathematical model based on a three-factor regression analysis of the experimental data for the change of the water resistance in the first half-period of a high voltage attenuating discharge pulse is proposed. A simplification of the proposed model is also suggested with good correlation (94,9 %) and a coefficient of determination 90,1 %.
