The abundant and cheap raw material terbium and cerium are selected as the activated dose in this study , their luminescence capability and principium in the strontium aluminate are studied , the afterglow of terbium in the strontium aluminate are discussed 我们选用原料丰富、价格相对便宜的铈、铽分别作为激活剂，分别研究它们在铝酸锶基质中的发光性和发光机理，并对铽在铝酸锶基质中的余辉机理进行了探讨。
The aluminates are used as the base and the rare earth materials are used as the luminescence center and trap center . the excitation resource can be visible light and man - made light , so this type of long persistent phosphor has the advantages of no - radiation and no need of electricity 它以铝酸盐陶瓷材料为基质，以稀土材料作为掺杂元素形成发光中心和陷阱中心，激发源可以为日光或人造光源，无污染，不消耗电能，是一种高效节能的固体发光显示材料。
In the study of terbium activate the strontium aluminate , a lot of experiment were done based the changes such as terbium , compounding temperature , reducer etc , the prime concentration of terbium and compounding temperature are confirmed , high quality green terbium actived phosphor are compounded 在铽激活的铝酸锶研究中，就改变铽的含量、合成温度、还原气氛等进行大量的实验，确定了铽最佳掺入量和最佳合成温度，合成了优质铽激活发绿色光的磷光体。
The silicate is more stable than the aluminate . and have better adaptable , but its luminescence properties do not achieve aluminates there a lot of work must be done for improving the luminescence properties of silicate . the paper have researched detailedly the system of sr2mgsi2o7 : eu2 + , dy3 + 而硅酸盐体系化学性质较铝酸盐体系稳定，具有更好的适应性，但硅酸盐体系的发光性能尚未达到铝酸盐体系水平，进一步提高硅酸盐体系的发光性能，还需做更深入的工作。
In the process of study , by a lot of experiments for analyzing luminescent properties " affecting factors , such as concentration ce and tb h3bo : i , synthesizing temperature and temperature reserving time , reducing condition , etc , it gives out a good foundation for synthesizing ideal rare earths luminescent materials activated by ce and tb in aluminates strontium host . the study indicated that photoluminesent aluminates strontium power activated by ce , tb , in sral . , 0 , , has a better luminescent effect . under the appropriate condition , srall . 0 ( that produce olivine light can be composed in 235nm or 365nm ul traviolet radiat ion act i vated by tbi07 , al , > 0 . i and srco : ! 研究表明，铈、铽共激活铝酸锶基光致发光粉体发光效果比较好；将tb _ 4o _ 7 、 srco _ 3和a1 _ 2o _ 3为原料，在适当的条件下可以合成在235nm或365nm紫外光激发下发出较强绿光的sral _ 2o _ 4 ： ( tb )发光粉；加入ceo _ 2合成sral _ 2o _ 4 ： ( ce ， tb )可以增强sral _ 2o _ 4发光粉体的发光性能：在合咸温度下保温时间对合成样品的发光效果有重要影响；随实验条件的改变可以制备出发红、黄、绿色光的磷光体；通过x射线物相分析法对合成物的物相组成进行测定。
4 . the interfacial soaking experiment of wollastonite / polypropylene composite material has further manifested that the cohesive strength of the interface between modified wollastonite 2 by stearic acid and polypropylene is higher than that of the interface between wollastonite and polypropylene , the interface between modified wollastonite 1 by stearic acid and polypropylene , the interface between modified wollastonite 3 by stearic acid and polypropylene , the interface between modified wollastonite by aluminate ester and polypropylene , the interface between non - modified wollastonite and polypropylene . 5 硅灰石增强复合材料的界面浸润性测量实验进一步表明，在硅灰石pp的复合体系中，改性硅灰石与pp基体的界面结合强度高于未改性硅灰石；硬脂酸改性硅灰石与pp基体的界面结合强度高于铝酸酯改性灰石；粒度为2号样的改性硅灰石与pp基体的界面结合强度高于1和3号改性硅灰石。
