建立了用分光光度计测定透光率,进而计算色度Hasen值和黄色指数的方法.用它代替目视比色法,不必配制、校检标准溶液,且测定结果可用确切的数值表示.
The method of measuring the light transmittance by spectrophotometer and then calculating the Hasen value and the yellow index of chroma was used instead of the visual colorimetric method, it is unnecessary to formulate and calibrate the standard solution, and the determination result can be expressed by the exact numerical value.
