一、前言温度控制在钢铁工业中极为重要。辐射测温常常用于非接触温度测量。下面列出辐射测温中的问题以及我们的解决办法。制造一种能准确测量不同发射率物体温度的高温计是困难的。我们发现,光谱发射率是波长的指数函数,通过在两种波长下测量和采用一种新的算 First, the preface Temperature control in the steel industry is extremely important. Radiation thermometry is often used for non-contact temperature measurements. The following is a list of the problems in radiation thermometry and our solution. It is difficult to create a pyrometer that can accurately measure the temperature of objects with different emissivity. We found that the spectral emissivity is an exponential function of the wavelength and that by measuring and using a new one at both wavelengths
