摘要：

In the present paper we define a quantity which describes how strong a polymer system is entangled. In MD computer simulations we apply this definition to samples of polymer melts which were generated with a specific large-scale structure, as characterized by their radius of gyration, end-to-end distance and the ''degree'' of mutual entanglement of the chains. The quantities mentioned above are monitored over the relaxation of the samples towards equilibrium.
