摘要：
The dynamic relaxation of various structural properties of a single freely jointed N-mer (N = 6,9,30) in explicit solvent at relatively high dilution is investigated by molecular dynamics. In the large-k region, the normalized intermediate scattering function I(k,t) appears to be a universal function of tk(x) with x = 2.9 +/- 0.1, in good agreement with experiments and close to the prediction of the Zimm model (x = 3).
