In this paper , the post - treatment problem of the prototypes that are made from the high molecular powder material is researched . the post - treatment solution such as infiltrating wax or resin is developed and this can greatly improve the capability of the prototype 本文研究了高分子粉末材料成型件的后处理问题，开发出的渗蜡和渗树脂的后处理方法极大的提高了成型件的性能，并且成功开发出了多种颜色的成型件。
The luminescence characteristics of these phosphors were investigated , and the luminescence mechanisms were also discussed . through this dissertation , the best preparation methods of these polychrome long afterglow phosphors can be provided for large - scale industrial production . and the application of these type of long afterglow will be expanded 经过系列实验，获得了红色、红橙色、黄绿色、蓝绿色、青色、蓝紫色等多种颜色的长余辉材料的最佳配方和制备工艺，研究了他们的发光性能，并初步讨论了各类材料余辉的发光机理。
