摘　　要：利用导数展开法，分别研究了在氢键链中外场对于扭结孤子和呼吸子的影响，得到了孤子迁移率及其共振频率，并指出当外场频率ω０满足时，呼吸子发生相锁。当ω０＝ωＨ时，扭结孤子作共振运动．The influences of the external field on the kink and the breather in the hydrogenbonded chain are discussed with the method of derivative-expansion. The mobility and the resonantfrequency of the kink are obtained. It is showed that if the frequency ω0 of the external-field satisfiesω0≤ωH,the phase locking between the breather and the external field will be occured,and if ω0=ωH,the kink will do the resonant motion with the external field.
