摘要
不同的工作条件将产生不同的气体放电现象,并具有不同的放电性质.在研究气体放电性质时,通常把放电分成两大类.一类是非自特放电,它是指存在外致电离源的条件下放电才能维持的现象.另一类是自持放电,它是指去掉外致电离源的条件下,放电仍能维持的现象.气体放电从非自持转变到自持过程称为气体的击穿过程;这种放电现象与理论由科学家汤生在上世纪初首先研究建立,故称为汤生放电.
Different working conditions cause different behavior of gas discharge with different discharge properties. In general, discharge is classified into two different kinds, one is non-self-sustained discharge, that is occurred at the existence of an extenal kmization source; the other is self-sustained, which can be maintained without the existence of the external ionization source. The conversion form the non-sustained to the sustained discharge is called the breakdown process of the gas. The investigation of this phenomenon and the set up of the Theory for the conversion were carried out by Townsend at the beginning of last century, thus it is called Townsend Discharge Theory.
