摘　　要：教学与科研的联动融合是教学改革的发展方向。本文展示了一个教学促进科研的案例,通过对教学内容的思考与系统梳理,凝结出了创新的研究思路。高分子结晶,是《高分子物理》课程的核心内容之一。其中,分子量对高分子结晶过程及聚集态结构的影响被广泛提及,高分子按分子量在结晶过程中发生分级,不同分子量会导致不同的聚集态结构。基于这两点,提出了高分子中会存在由于分子量多分散性导致的聚集态结构规律分布的猜想。验证这一猜想促进了一种新型嵌套球晶织构的发现,并为其形成机理的研究提供了关键指导。本文体现了教学促进科研模式的可行性与优越性,以期为科教融合提供有益的启迪。The integration of teaching and scientific research is the development direction of teaching reform.Here,a case of teaching promoting scientific research is presented.An innovative idea has been extracted from thinking and systematic digest of teaching contents.Polymer crystallization is one of the core contents of the“Polymer Physics”course.Therein,it is widely considered that molecular weight shows a great influence on polymer crystallization process and aggregated structure.First,fractional segregation is observed during crystallization based on molecular weight.Second,different molecular weights lead to different aggregation structures.Hence,it is speculated that there would be a distribution of aggregation structure in polymers due to the polydispersity of molecular weight.The speculation promotes the discovery of a novel nested spherulite texture and provides key guidance for the study of its formation mechanism.By showing the feasibility and superiority of the teaching promoting scientific research,this paper provides an example of the integration of teaching and scientific research.
