对材料样品黑度系数的测定方法很多,归结起来主要有两类:一是辐射计探测样品反射或发射的能量,称之为能量法;二是量热法。本文介绍的是用能量法来测量样品的黑度系数,即用两台不同吸收波长的辐射计,接收同一样品在某一温度下的辐射能量,测出两台辐射计各自辐射温度,联立求解两台辐射计的刻度方程,从而求解出样品的真实温度和黑度系数。 There are two main methods to determine the blackness coefficient of the material samples. There are mainly two types of materials: one is the energy reflected or emitted by the radiometer to detect the sample, which is called the energy method; the other is the calorimetry. This article describes the use of energy method to measure the blackness coefficient of the sample, that is, with two different absorption wavelength of the radiometer to receive the same sample at a temperature of radiation energy, measured the radiation of two radiometers temperature, simultaneous Solve the scale equation of the two radiometers, so as to solve the real temperature and blackness coefficient of the sample.
