The key problems in radiation thermometry are the unknown emissivity of objects and the background noise from surroundings.The author developed a new method of radiation thermometry for low emissivity metals having normal emissivity less than 0.1 such as aluminum, cold rolled steel and stainless steel at temperature ranging from 310K to 370K.The method makes use of directional emissivity of metals and also of the specularly reflecting property of the metal surface at long wavelength of 8-10mum range.The author also developed a new radiation thermometer for the measurment of near roomtemperature with high signal-to-noise ratio (S/N). The thermometer which uses an HgCdTe semiconductor sensor, is compact and insensitive to tempetrature changes of the surroundings. Its major breakthrough owes much to the fact that the sensor is cooled and controlled by Peltier thermoelectric devices and that the sensor serves as reference radiator. A well designed optical system with a chopper and a concave mirror shuts off stray radiation, thus improving the S/N.

辐射测温的关键问题是物体的发射率未知和环境背景噪声，作者提出了一种适用于法向发射率小于0.1的低发射率金属（如铝）的辐射测温新方法，该方法利用了金属的定向发射率和镜面反射率，在8- 10 μ m的长波范围内测量了金属表面的性质，并研制了一种新的近室温高信噪比辐射温度计。该温度计采用HgCdTe半导体传感器，结构紧凑，对环境温度变化不敏感。它的主要突破在很大程度上归功于传感器由Peltier热电器件冷却和控制，并且传感器用作参考辐射器。一个设计良好的光学系统与斩波器和凹面镜关闭杂散辐射，从而提高信噪比。
