一、比色法(1)比色器(图1) 用于颜色的视力比较。先将标准物料置于S处并且测得光电管P对于白、红、绿和蓝光(由光源I经F处的滤光片而得)的感应。试样也以同样的方法操作。感应值提供视力比较的结果。特点:用于比较油漆、染料、纸张等等的颜色。也用于比较颜色的透射能力。(2)光电比色计(一般介绍) First, the colorimetric method (1) colorimeter (Figure 1) for color vision comparison. The standard material was first placed at S and the sensing of the phototube P for white, red, green and blue light (obtained from the light source I through the filter at F) was measured. The sample is also handled in the same way. Sensing values ​​provide the result of a comparison of eyesight. Features: Used to compare colors of paint, dye, paper, etc. It is also used to compare the color transmissivity. (2) Photoelectric Colorimeter (General Information)
