为了优化配煤，提高镜质体反射率测试精度，以MSP UV-VI2000型光度计为例，介绍了测定镜质体反射率的原理和测试流程。推导出了测定反射率的通用公式和专用公式。对2种公式进行比较发现：专用公式需要校准设备，过程繁琐。通用方法具有普遍适用的特点，其基本步骤为人工读数，做曲线，计算反射率值，绘制直方图。根据公式，分析了工作曲线的最大量程，反射率的分辨能力。重点比较分析了不同斜率的2条光度计工作曲线以及在测试过程中如何选择工作曲线。最后提出了光度计测定镜质体反射率应遵循的原则。

In order to optimize coal blending process and improve test precision of vitrinite reflectance,taking MSP UV-VI2000 photometer as research object,introduced its working principle,process. Obtained the general formal and special formula of vitrinite reflectance. The comparison of the two formulas show that,the special formula needs to correct equipment and the process is complicated.The special formu-la has an universally applicable characteristic. The experimental procedure includes measuring,drawing curve,calculating reflectance and drawing histogram.Based on the formula,analyze the maximum measurement range and resolving power of photometer.Compare two working curves which have different slope.Provide principles with which should be complied when measuring the reflectance with photometer.
