By considering the anisotropy in the quasi-two-dimensional Cu—O plane for the cuprate compound,on the basis of the two-dimensional bisoliton model estabished,the nonlinear local coupling efects caused by the interactions between electrons and phonons in the strongly anisotropic Cu—O plane are investiged.The formation of bisoliton and its bound states are discussed.The periodic bisoliton solution is given in the form of conoidal elliptic integral.The pairing energy for the two quasi-particles,the effective mass and the stability of the bisoliton are analysed in terms of the anisotropy.
