A method is presented for obtaining spectroscopic temperatures in shock tubes using relative emission from two wavelength regions of a molecular band system. Experimental results are given for the OH violet system obtained in the reflected wave region near 3500 degrees K. These results show that equilibrium conditions prevail and that the spectroscopic temperatures agree with those calculated from shock wave velocities. A resume of the appropriate theoretical considerations is given along with a detailed discussion of the experimental techniques required. A brief discussion is also given of some other techniques used to measure temperatures in shock tubes, and comments are made regarding these methods as well as on some of the general problems associated with spectroscopic temperature measurements in shock tubes.
本文介绍了一种利用分子谱带系统两个波长区域的相对发射来获取激波管中光谱温度的方法。给出了在3500K附近反射波区域获得的OH紫光系统的实验结果。这些结果表明存在平衡条件，且光谱温度与根据激波速度计算出的温度一致。文中给出了相应理论考虑的概要，以及对所需实验技术的详细讨论。还简要讨论了用于测量激波管中温度的其他一些技术，并对这些方法以及与激波管中光谱温度测量相关的一些一般问题进行了评论。
