描述了空气中间歇点对平面电晕的快速示波器分析技术。这样的分析表明，正点爆发脉冲电晕是由一个初始脉冲和随后在不同时间间隔的二次脉冲组成的。两个脉冲的持续时间都小于10−7秒，根据电压的不同，初始脉冲具有从1到2×107的离子，次级脉冲具有从1到5×106的离子。脉冲之间的时间间隔范围从离子穿过间隙的清除时间（毫秒）到远高于阈值的二次脉冲短至2微秒的随机间隔。因此，与盖革计数器术语类似，死区时间从2微秒开始运行，清除时间以毫秒为单位，对应于次级点附近空间电荷的局部清除，以及从间隙的低场区域去除大量空间电荷。分析了从阈值到稳定电晕的完整事件序列，并表明空气中负离子形成的自我计数占主导地位。
Techniques for fast oscilloscopic analysis of intermittent point‐to‐plane coronas in air are described. Such analysis shows the positive point burst pulse corona to consist of an initial pulse followed by secondary pulses at varying time intervals. The duration of both pulses is less than 10−7 second, the initial pulses having from 1 to 2×107 ions and the secondaries from 1 to 5×106 ions depending on the voltage. Time intervals between pulses range from the clearing time of ions across the gap (milliseconds) to random intervals as short as 2 microseconds for secondary pulses well above threshold. Thus, in analogy to Geiger counter terminology dead times run from 2 microseconds up, and clearing times are in the order of milliseconds corresponding to local clearing of space charge near the point for secondaries, and removal of massive space charge from the low field region of the gap. A complete sequence of events from threshold to steady corona is analyzed, and indicates the predominance of self‐counting through negative ion formation in air.
