中文摘要：
黏度法测黏均分子量是高分子物理课中的一个基本操作实验,但黏度法测聚乙烯醇黏均分子量实验中存在仪器烘干过程长、乌氏黏度计易损坏、测定中容易起泡等急需解决的问题。本文结合作者多年指导学生实验的经验,针对实验中长期困扰广大师生的几个问题提出了简便易行的解决办法。
英文摘要：
Measurement of average viscosmetric molecular weight by using viscosimetry is a basic experiment in Polymer Physics course.In the measurement of average viscosmetric molecular weight of Poly（vinyl alcohol）,the long dry time of viscosimetry,the damageable instrument and easy to bubble are common problems that must to be solved.Based on the experience of teaching in experiment,the author provided some easy and feasible methods to solve the problems that teachers and students are facing.
