| 摘 要： | 本文用简单的数学关系导出了稀溶液中由同一种单体组成,分子量相同的环型和线型高分子线团的等效球体半径比r环/r线和摩擦因子比f环/f线均为1/(η]线/η]环)1/3.在不考虑排斥体积效应的情况下,这个比值为2-1/3即0.7937.均方半径比为0.79372≈0.63.

| Abstract: | Two correlation equation repu·ring/repu·opcn = 1/(η])opcn/η]ring)3 and fring/fopcn=1/(η])opce/V]ring)1/3 of the ring shaped and linear shaped polymercoils with both same monomer and molecular weight in dilute solution have been derived. When there isn't excluded volume effect, requ. ring/requ.opcn=fring/fopcn=2-1/3≈ 0.7937 and 〈S2〉ring/〈S2〉 open = (2-1/3)2≈0.63. |
