摘要：

The results of the estimation of the strength of the electric field that is formed in polar liquid near the liquid-gas interface of a collapsing gas bubble are presented. A double electric layer and flexo- and thermoelectric effects are considered as field sources. It is shown that the field strength in water can reach 10(9) V/m, and the dimensions of the strong field area can be up to several tens of micrometers. These results are an argument for the earlier made assumption that there may be two sources of luminescence in polar liquid-gas systems: adiabatically heated gas inside the bubble and channels of electrical breakdowns in the liquid. In the case of nonpolar liquid, no second source is formed. The experiment for testing the model is proposed.
