Abstract

The emission spectra of the CaO molecule behind the front of a reflected shock wave in a shock tube with a diameter of 50 mm has been studied. The spectra are recorded using a specially designed compact spectrometer with a CCD array, as well as using a spectrometer based on an upgraded MDR-12 monochromator and a Sony SLT-A77 camera as a radiation detector. The emission spectra of CaO are recorded at different gas temperatures. The obtained results can be used to test theoretical models of the emission spectra of the CaO molecule at different temperatures.

冲击管实验研究540-650 nm波长范围内CaO分子的发射光谱

摘要

研究了直径为50 mm的激波管中反射激波波前的CaO分子的发射光谱。使用专门设计的带有CCD阵列的紧凑型光谱仪,以及使用基于升级的MDR-12单色仪和Sony SLT-A77相机作为放射线检测器的光谱仪,记录光谱。CaO的发射光谱是在不同的气体温度下记录的。所得结果可用于测试不同温度下CaO分子发射光谱的理论模型。
