摘要	The translocation dynamics of a single biopolymer chain through a nanopore in a membrane is investigated by taking the coil - helix transition into account. Based on the changing of the free energy due to the coil helix transition, the mean. rst passage time t is obtained, and then the corresponding numerical simulations are presented under di. erent conditions. It is shown that the coil - helix transition can signi. cantly shorten the translocation time of the biopolymer chain. In addition, we also discuss the scaling behaviour for t with the chain length N and some related problems.
