摘要：

The coupling model is reformulated using a Fokker-Planck approach to generalize the Rouse model to include time-dependent rate slowing down by entanglement coupling. The results compare favorably with data of several computer simulations. In particular, we point out the results of the normal-mode analysis of the molecular dynamics simulations of Kremer and Grest are in good agreement with the coupling model but at variance with the reptation model.
