摘　　要：研究一类厄尔尼诺-南方海涛(ENSO)的耦合系统振子的模型.利用Sinc-Galerkin方法,把求解非线性微分耦合系统问题转化为解非线性代数系统,并由Newton法得到其近似解.A class of coupled system oscillator model for El Nino-Southern Oscillation （ENSO） was investigated. Using Sinc-Galerkin method, the solution of nonlinear differential coupled system was converted to that of nonlinear algebraic equations. Their approximate solution was obtained by using Newton＇s method.
