中文摘要：

基于 Wronskian 技术和宽松的对， nonisospectral BKP 方程的两倍 Wronskian 答案明确地被介绍。速度和一 soliton 的动态影响被讨论。二 soliton 的 Soliton 回声借助于密度分布被显示出。Soliton 性质也在不同类的媒介被调查。

英文摘要：

Based on the Wronskian technique and Lax pair,double Wronskian solution of the nonisospectral BKP equation is presented explicitly.The speed and dynamical influence of the one soliton are discussed.Soliton resonances of two soliton are shown by means of density distributions.Soliton properties are also investigated in the inhomogeneous media.
