针对大学理工科相关课程中的一些理论知识较为抽象、学生对此类知识学习兴趣淡薄这一问题,尝试提出以"课外趣味科研"作为平台,灵活地将教材理论知识和相关科研实验相结合,通过学生在实验操作中直观的理解,发掘其对相应理论知识的学习兴趣,从而增加其对知识点的理解深度,并达到学以致用的目的.作为示例,文章以"Ca10Na(PO4)7:Eu3+,Na+荧光粉材料的制备和发光性质研究"这一课题为基础,结合原子物理学及材料学中的能级跃迁、离子掺杂、X射线粉末衍射分析等理论,系统地阐述如何通过课外科研实践来辅助教学,实现理论与实践的有效结合,这些对相关课程的教学改进是一个很有价值的参考.
針對大學理工科相關課程中的一些理論知識較為抽象、學生對此類知識學習興趣淡薄這一問題,嘗試提齣以"課外趣味科研"作為平檯,靈活地將教材理論知識和相關科研實驗相結閤,通過學生在實驗操作中直觀的理解,髮掘其對相應理論知識的學習興趣,從而增加其對知識點的理解深度,併達到學以緻用的目的.作為示例,文章以"Ca10Na(PO4)7:Eu3+,Na+熒光粉材料的製備和髮光性質研究"這一課題為基礎,結閤原子物理學及材料學中的能級躍遷、離子摻雜、X射線粉末衍射分析等理論,繫統地闡述如何通過課外科研實踐來輔助教學,實現理論與實踐的有效結閤,這些對相關課程的教學改進是一箇很有價值的參攷.

Aiming at the problem that some theoretical knowledge is abstract for the relative courses of science and engineering and the students have weak interest to this kind of knowledge. this paper proposes tentatively to combine the theoretical knowledge of textbooks and the relative scientific research experiments based on "extracurricular interesting scientific research". According to the students' intuitive understanding from the operations in experiments, it can develop their interest of studying the corresponding theoretical knowledge,which will increase the depth of understanding to the knowledge points and achieve the aim of making study serve the practical purpose. This paper takes the project"Investigations on preparation and luminescence properties of Ca10Na(PO4)7:Eu3+,Na+ phosphors" as an example to interpret systemati-cally how to assist teaching by using the extracurricular scientific research practices and combine the the-ory and practice effectively on the basis of combination for the energy level transition,ions doping,X-ray power diffraction and so on. All the above results could be valuable reference to improve instruction of the relative courses.
