[The temperature field partition for primary spectrum pyrometry].

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 given. Ths study is significative for the applications of primary spectrum pyrometry.
