电负性混合气体临界电场强度的确定

本文讨论了确定电负性混合气体临界电场强度的两种方法。一是用电负性混合气体中各组成气体的预放电参数来确定按任意比例混合的气体之临界电场强度。另一是由高能脉冲激光释放电子,记录预放电电子电流波形来确定混合气体的临界电场强度。用这两种方法确定N₂和SF₆混合气体的临界电场强度,其结果十分符合。 关键词：

DETERMINATION OF CRITICAL FIELD STRENGTH IN ELEC-TRONEGATIVE GAS MIXTURES

Presented in this paper are two methods used for determining the critical field strengths in electronegative gas mixtures. One of the two methods is to use the predischarge parameters of the gases for the determination of the mixtures with any concentrations. And the other is to use the recordings of the electron current waveforms in the gas mixtures studied in a discharge chamber. The critical strengths in mixtures of SF₆ and N₂ were determined by the two methods and good agreement has been achieved.
