摘要：
The absorption characteristics of photo-ionizing VUV radiation emitted by corona discharges in the pressure range from 20 to 750 Torr in dry and humid air were measured. The experimental results are compared with data and approximation formulae obtained by others. For a wide region of pressure and absorption path length, the formula proposed by Zheleznyak et al. (Teplofiz. Vysokih Temp. 1982,20,423) seems to be the most reliable for approximation of our results for dry air. We propose a modification of that formula for humid air. The obtained results are suitable for modelling of discharge development in ambient air.
