摘　　要：从辐射的能级跃迁理论和相互关联的变量间的数学关系两个方面,对为了避开传统红外测温方法遇到的辐射率修正困难而提出的红外测温新方法进行了分析;在数据处理方面,讨论了函数形式未知的普遍情况;比较了传统方法与新方法的基本思路,研究表明:新红外测温方法与传统红外测温方法并不矛盾,它将传统红外测温方法从特殊情况推广到了普遍情况.实测结果也证明,通过该方法可有效地提高温度测量的准确度.For the new temperature measurement method which was proposed to avoid the difficulty in radiance modifying in the traditional method, it is analyzed by the theory of transition between energy levels and the mathematical relation between correlated varieties, the prevalence of unknown function form is discussed in data processing. The result shows that the new method is a popularization of the traditional one; it could be applied to general situation. The experimental results also prove that the temperature measurement accuracy can be effectively improved by the new method.
