本文描述了干带放电的电流特性。介绍了模拟干带的模型电极。研究了电压和电流波形、发射光谱及其强度、旋转温度等对放电的影响。结果表明，在半个交流电压周期内，观察到了连续和间歇两种不同的放电类型。它们分别具有连续电流和发光、脉动电流和间歇发光的特征。连续放电的持续时间随着串联电阻的增大而缩短，而间歇放电的持续时间则随着串联电阻的增大而增大。连续放电和间歇放电的旋转温度分别约为6000K和1500K。与间歇放电相比，连续放电时与电解液相关的光谱发射强度较高，且随串联电阻的增大而减小。在间歇放电过程中，与氮分子有关的光谱发射强度几乎是恒定的，与串联电阻的大小无关。连续放电和间歇放电的特征分别对应于终止的局部弧光和火花(闪烁)的特征。
This paper describes the current dependence of dry-band discharge. Model electrodes that simulated the dry-band was introduced. The dependence was examined on the voltage and current waveforms, emission spectra and their intensities, rotational temperature, etc. As a result, two different discharge types, continuous and intermittent discharges, were observed in a half cycle of applied ac voltage. They were characterized by continuous current and light emission, and by pulsative current and intermittent light emission, respectively. The duration of the continuous discharge decreased with the value of series resistance, while that of the intermittent discharge increased. The rotational temperatures of the continuous discharge and the intermittent discharge were about 6000 K and 1500 K, respectively. The spectral emission intensity related to the electrolyte during the continuous discharge was higher compared with the intermittent discharge, and decreased with the value of series resistance. The spectral emission intensity related to nitrogen molecule during the intermittent discharge was almost constant irrespective of the value of series resistance. The characteristics of the continuous and intermittent discharges corresponded to those of the terminated partial arc and spark (scintillation), respectively.
