【 摘 要 】

The experimental results of the absolute measurements of spectral radiation of air were obtained on the double diaphragm shock tube of Laboratory of Kinetic Process in Gases of Institute of Mechanics MSU. The radiative properties of nitric oxide in the spectral range 190-290 nm were investigated experimentally. The time dependence of the emission of molecular bands for NO shock wave velocities of 4-10 km / s were obtained. The article discusses the problems of absolute power measurement in the radiation behind shock wave front.
