摘要：

We consider a nonlinear DNA model which has discontinuities of the mass distribution and spring constant distribution. Incident, reflected and transmitted waves are described by the nonlinear Schrodinger equations on different coordinates. Fission and reflection of a soliton due to the discontinuity are explicitly shown. Implications of the results to DNA dynamics are discussed.
