高分子结构是组成高分子的不同尺度的结构单元在空间的相对排列,涉及高分子链的近程结构、远程结构和聚集态结构。在高分子物理教学中,从不同维度讲述“三个结构”并分析其影响因素,使学生深入理解三种结构的区别和联系,从而更好地掌握高分子链结构。 Polymer structure is composed of different sizes of polymer molecules in the relative arrangement of space units, involving the polymer chain of short-range structure, remote structure and aggregation state structure. In the teaching of polymer physics, we tell about the “three structures” from different dimensions and analyze the influencing factors so that students can understand the differences and connections among the three kinds of structures so as to better grasp the structure of polymer chains.
