计算回转半径和温度的关系
|
|
请问各位高分子大神。如何计算回转半径和温度的关系呢？ 题目： （1）第一种情况 The Kuhn monomer is described as a sphere. 问题 Calculate and plot the theoretical curve of the radius of gyration versus temperature for your polymer poly(A) with molar mass in the appropriate temperature range. （2）第二种情况The Kuhn monomer is better described as a cylinder of length equal to the Kuhn length l and smaller diameter d. The excluded volume parameter of a cylinder is given by V=l2d，and the third virial coefficient is given by C=l3 d3. 问题：For your polymer poly(A) with molar mass assume the segment to be cylindrical instead of spherical. Calculate the theoretical curve of the radius of gyration versus temperature for your polymer poly(A) with molar mass in the appropriate temperature range for the aspect ratio of your Kuhn segment as well as an aspect ratio 20 times as large. 没有什么高分子物理基础，所以很多专业名词不会翻译，直接把随堂练习题目复制过来了。 |
