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.
