摘　　要：文中指出:红外系统距离方程中,大气透过率本身就是随距离R迅速变化的函数,从而将红外系统的距离方程改写为更加准确的表达形式。根据这一事实,文中提出了对求解R的结果是否正确的判断准则,并给出了求解距离R的正确方法。In this paper, it is indicated that： in the range equation of IR systems, the atmospheric transmittance τa itself is a rapidly varying function of range R, therefore, the range equation of IR systems is modified into a more exact expression. Based on this fact, the criterion of judging whether the solutions of R are correct or not is suggested, and the corrcet methods of solving the range R are given.

关 键 词：红外系统 距离方程 大气透过率函数τa(R) 距离R的正确解法
