| 英文摘要 | The propagation of a localized excitation and the thermodynamic properties in DNA double helices due to stretching vibration of hydrogen bond are discussed. The stretch of the hydrogen bonds is considered as a nonlinear chain with cubic and quartic potential. The analytic solution of the solitary wave is obtained by using the continuum approximation and its stability has been discussed. With the help of the thermodynamic Green function technique, the temperature and anharmonicity effects on the thermodynamic properties of DNA are investigated. The theoretical calculation of the specific heat in DNA at low temperature is consistent with the experimental result. The numerical simulation of the differential-difference equation shows that the solitary wave is pinned by the lattice. It is also pointed out that the conformational transitions from B-DNA to A-DNA can occur in the case of asymmetry potential with quartic term. (C) 1999 Published by Elsevier Science B.V.
