摘要

利用莫斯科国立大学力学研究所的激波管进行了一系列实验，确定了在气体压力为1托、激波速度为3.4 ~ 4.5 km/s的条件下，激波加热氧气在213 ~ 260 nm波长范围内的辐射吸收光谱。在将实验数据与光谱动力学模型计算结果进行比较的基础上，分析了舒曼-龙格体系中结合-结合和结合-非结合跃迁对氧吸收特性的影响。

Experimental and Theoretical Studies on the Absorption Properties of Shock-Heated Oxygen

A series of experiments are conducted with the use of a shock tube at the Institute of Mechanics, Moscow State University to determine radiation absorption spectra in shock-heated oxygen in the wavelength range of 213–260 nm at a gas pressure of 1 Torr and shock wave velocities ranging from 3.4 to 4.5 km/s. Based on a comparison of the experimental data with the results of calculations using a spectral-kinetic model, the effect of bound–bound and bound–unbound transitions in the Schumann–Runge system on the absorption properties of oxygen is analyzed.
