Emission spectra of argon behind the front of a strong shock wave are studied in the range of shock-wave velocities of 4.6–8.3 km/s and pressures before the wave front of 0.25–5.00 Torr. Time-integrated sweeps of radiation in a wide spectral range from the ultraviolet to infrared (190–1100 nm) and time dependences of the argon radiation intensity at wavelengths of 420, 532.8, and 740 nm are obtained. Three characteristic stages of the temporal evolution of the emission lines are defined. The dependences of the duration and intensity of the emission lines on the initial gas pressure and shock-wave velocity are established. Data are obtained on the background radiation intensity and can be used to separate the intensities of certain argon-atom lines from the total radiation.

在4.6–8.3 km / s的冲击波速度和0.25–5.00 Torr的波前之前的压力范围内，研究了强冲击波前的氩气的发射光谱。在从紫外到红外（190-1100 nm）的宽光谱范围内，对辐射进行了时间积分扫描，并获得了波长为420、532.8和740 nm时氩气辐射强度的时间依赖性。定义了发射线随时间变化的三个特征阶段。建立了发射线的持续时间和强度对初始气压和冲击波速度的依赖性。获得有关背景辐射强度的数据，并可用于将某些氩原子线的强度与总辐射分开。
