实验研究了单、双色辐射温度计与被测表面之间所形成的光路，以及其中存在有水膜和水蒸汽时对该两种辐射温度计示值的干扰。 Experiments were conducted to investigate the optical paths formed between the single and two-color radiometric thermometers and the surface under test, as well as the interference with the indication of the two radiation thermometers in the presence of water films and water vapor.
