Influence of the proton transport on the electric strengthening and breakdown of crystalline materials V. M. Timokhin Admiral Ushakov State Maritime University 93 Lenin av., Novorossiysk, Krasnodar region, 353918, Russia E-mail: t.v.m@inbox.ru The problem of the electric strengthening has been and remains the actual at present. <...> The necessity of application of superthin electroinsulating materials demands the careful investigation and working out of their diagnostics methods with the purpose of prolongation of the working period and opportune replacement. <...> The most electroinsulating materials are made of crystals with hydrogenous bonds. <...> It follows from this the problem of proton transport influence on electric strengthening and breakdown. <...> PACS : 77.22.Ej, 77.22.Jp Keywords: proton transport, electric strengthening, breakdown, thermostimulated currents, hydrogenous bonds, diagnostics. <...>
