谱色测温法是该课题组提出的一种新的辐射测温法。针对可探测的温度区间,通过辐射光谱耦合信息的分析,考察了区间内所有温度点都能同时被失真测量的必要条件;对于不满足该条件的测量,提出了温度场分区的概念,描述了温度场分区的步骤,并给出了相应的数值模拟结果。研究结果将对谱色测温法的应用具有指导意义。
In the applications of primary spectrum pyrometry to the detection of temperature, through the analysis of the coupled multi-channel signals, the authors investigated the necessary condition under which all temperatures can be measured simultaneously and effectively. For the case not satisfying the above condition, the authors put forward the concept of temperature field partition. And the process of the temperature field partition is detailedly described, and the simulation results are giverh Ths study is significative for the applications of primary spectrum pyrometry.
