摘　　要：为了向学生传授逻辑性思考和系统性设计实验的方法,设计了以剑麻纤维为填料,以不同分子量的聚丁二酸丁二醇酯(PBS)为基体的实验,研究了分子量对界面结晶形态以及界面剪切强度(IFSS)的影响。通过结果对比分析、理论分析和设计验证,打破了传统的教学模式,训练了学生的实验逻辑思维能力,锻炼了学生系统设计实验的能力,构建形成了以知识-能力-素质-创新为主线的实验教学体系。In order to develop students’ capacity of logical thinking skill and systematic design experiment, polybutylene succinate with different molecular weight reinforced with sisal fiber are prepared. The effect of molecular weight on the morphology of interfacial crystallization and interfacial shear strength are investigated. Through analysis of the results, theoretical analysis and verification by designing experiment, traditional experimental model is changed, which can train students’ capacity of logical thinking skill and systematic design experiment and establish the experimental teaching system based on knowledge, ability, quality and innovation.
