利用双线性方法研究了离散耦合非线性薛定谔方程的孤子解。分别在散焦-散焦和聚焦-聚焦情况下，给出了暗-暗和亮-亮型N-孤子解的Pfronan表达式.
The soliton solutions for discrete coupled nonlinear Schrödinger equations are investigated by using bilinear formalism. Pfaffian expressions of the N‐soliton solutions of dark–dark and bright–bright types are explicitly given for the defocusing–defocusing and focusing–focusing cases, respectively.
