本文叙述了在空气中对平面电极和针电极间负无脉电晕的观测，并通过测量放电间隙的亮度和空间电位，报道了负无脉电晕向火花击穿转变的特征。为了测量空间电位，使用了三极管静电计。在火花击穿前，平面电极附近的亮度最强，从负无脉电晕到火花击穿的过渡从平面电极开始。在火花击穿，在这个区域中的电场强度是恒定的间隙长度范围从8至16毫米。这个电场强度是约43 V cm-1托-1。在平面电极附近满足α>或= η是负无脉电晕向火花击穿转变的条件。
The authors describe observations on the negative pulseless corona in air between plane and needle electrodes and reports the characteristics of the transition from the negative pulseless corona to spark breakdown by measuring the luminosity and the space potential of the discharge gap. For the measurement of the space potential, a triode tube electrometer was used. The luminosity near the plane electrode is strongest just before the spark breakdown, and the transition from negative pulseless corona to spark breakdown starts from the plane electrode. At the spark breakdown, the field intensity in this region is constant for gap length ranging from 8 to 16 mm. This field intensity is about 43 V cm-1 Torr-1. It is the condition of the transition from negative pulseless corona to spark breakdown that the relation alpha >or= eta is accomplished near the plane electrode.
