摘要
认为张晓云在“有关聚合物平均分子量和分子量多分散性的教学点滴”一文中对聚合物分子量分布宽度指数的定义以及由此得出的结论是值得商榷的。本文介绍了具有统计意义的分子量分布宽度指数的定义 。
The definition of breadth parameter of macromolecular weight distribution, together with the conclusion as presented by Zhang Xiao yun in the article entitled “A little about averrage molecular weight and polydispersity of polymer in teaching”, deserved to be discussed. In this paper the expression of breadth parameter of molecular weight distribution with statistical sense was introduced. The interrelationships among four different average molecular weights are briefly discussed.
