摘要：

By considering the finite lifetime of excitation and the band structure of the finite chain in the polymer, the authors interpret the two-peak structure in the spectrum of the third-order nonlinear susceptibility of trans-polyacetylene. The numerical result of the theoretical calculation agrees with the spectrum observed in experiments.
