【摘要】 将动态机械分析仪应用于高分子物理实验教学中,有助于学生加深对高分子物理课堂所学粘弹性现象的理解。我们围绕该仪器设计了多套研究性实验项目,使学生充分了解动态力学分析原理和方法,学会使用该仪器测定高分子的粘弹性能,并从分子运动的角度来解释高分子的动态力学行为。这些实验项目的设置,对培养学生的实验技能和动手能力、综合利用所学知识分析和解决问题能力和激发科研兴趣等方面起到了积极作用。更多还原

【Abstract】 The application of dynamic mechanical analyzer in polymer physics experiment teaching will help students to deepen their understanding of viscoelastic phenomena in polymer physics. We designed several experimental experiments around this instrument,so that students fully understand the principles and methods of dynamic mechanical analysis,learn to use this instrument to determine the viscoelastic properties of polymers,and explain the dynamic mechanical behavior of polymers from the molecular movement point of view. The setting of these experiments has played a positive role in cultivating students’ experimental skills and practical ability,comprehensively utilizing the knowledge to analyze and solve the problems,and stimulating students’ scientific research interests.更多还原
