摘      要：Dissipative particle dynamics simulations are performed to study the forced translocation of polymer through a nanopore inside which the polymer experiences a driving force *** interaction(HI) is taken into account for the polymer in good *** find that the mean translocation timescales with the polymer length N as～Nx with a = 1.26 ± 0.03 close to a theoretical prediction,and the probability distribution of s can be described by a Gaussian *** results show that the dynamics of polymer translocation with the HI is different from that without the ***,the exponent d in the scaling～δ F-dis found not to be affected by the HI effect.
