结果表明，气隙的均匀击穿必须伴随着Stoletov效应，即在给定电压脉冲下的电流最大压力。计算了不同气体中脉冲非自持放电的Stoletov常数。这些常量还决定了最小击穿延迟时间。结果表明，在充气二极管中产生的电子束的最大电流是在脉冲期间对应于最大电流的压力和对应于电子漂移长度的电极间距下达到的。
It was shown that a uniform breakdown of a gas gap must be accompanied by the Stoletov effect, i.e., a current maximum in pressure at a given voltage pulse. Analogues of the Stoletov constant were calculated for the pulsed non-self-sustained discharge in various gases. These constants also determine the minimum breakdown delay time. It was shown that the maximum current of the electron beam generated in the gas-filled diode is reached at a pressure corresponding to the maximum current and for an electrode spacing corresponding to the electron drift length during the pulse.
