为了加速信函自动化分类工作,我国于1980及1982年分别发行了磷光邮票各一套。为了检查磷光邮票的质量,给分理机的设计部门提供参考数据,本实验用荧光分光光度计及其磷光测定附件,在室温对磷光邮票的磷光光谱特性和磷光强度进行了测试。 In order to speed up the automated classification of letters, a set of phosphorescence stamps were issued respectively in 1980 and 1982 in our country. In order to check the quality of phosphorescence stamps, reference data was provided to the design department of the splitter. In this experiment, the phosphorescence spectra and phosphorescence intensity of phosphorescence stamps were tested at room temperature with a fluorescence spectrophotometer and its phosphorescence measuring attachment.
