在可见光波段内对光谱热发射率模型进行了合理的假设后 ,揭示出等温连续辐射光谱表达的颜色轨迹在色度图上表现为有限直线段 ,并且该线段可划分为单解段和双解段 ;根据该线段上的颜色求解温度 ,在单解段上颜色和温度一一对应 ,在双解段上一个颜色和两个温度相对应 .最后 ,还将彩色测温方法中的颜色域划分成了单解域和双解域
After reasonable assumption of the spectral emissivity model in the visible wavelength band, it is revealed that the color locus expressed by the isothermal continuous radiation spectrum appears as a finite linear segment on the chromaticity diagram, and the segment can be divided into single-segment and dual-solution According to the color of the line segment to solve the temperature, the color and temperature in the single solution segment correspond to each other, in the double solution segment, one color corresponds to the two temperatures.Finally, the color field in the color temperature measurement method is also divided Has become a single domain and double solution domain
