利用计算机断层摄影技术观测了导线电晕的亮度。并将计算结果与线电晕的光输出进行了比较。通过计算多伊奇假设下的电离和附着过程，确定了电晕场中各类载流子的空间电荷和电流密度的空间分布，并与实验结果进行了比较。沿着电极对称轴的计算结果与测量结果非常一致。遗憾的是，在光度分布方面，实验结果与多伊奇假设下的计算结果略有差别。
Luminosity of wire corona has been observed by the technique of the computed tomography. The light output from wire corona has been compared with the calculated result. Spatial distributions of space-charge and current density of each type of charges carrier in a corona field has been also determined by computing the ionization and attachment process under the Deutsch assumption and compared with experimental results. The calculated results along the symmetry axis of the electrodes show very good agreement with measurements. Unfortunately, there is a slight difference between the experimental results and those of the calculation under the Deutsch assumption in the distribution of luminosity.
