在各种流动条件下，对电子束激发的氮气沿自由射流轴线的旋转温度进行了沿着测量。从等熵流方程计算的温度进行了比较与那些来自旋转光谱。两个温度测定之间的差异导致了在300和78°K热力学平衡下氮的转动光谱的研究。“静态”气体测量的结果表明，现有的电子束激发-去激发过程的模型可能是不正确的。
Measurements of the rotational temperature of electron‐beam excited nitrogen have been made along the axis of a free jet under various flow conditions. Temperatures calculated from the isentropic flow equations are compared with those derived from the rotational spectra. Discrepancies between the two temperature determinations led to an investigation of the rotational spectrum of nitrogen in thermodynamic equilibrium at 300 and at 78°K. Results of the ``static'' gas measurements are presented which indicate that existing models of the electron‐beam excitation—de‐excitation process may be incorrect.
