研究了一个厄尔尼诺大气物理机理振荡 .利用变分迭代理论 ,简捷地得到了该模型解的近似展开式 .通过与特殊情形下模型的精确解的比较 ,得到的一次近似解具有完全符合的精确度 .
An oscillation of the physical mechanism of El Niño is studied. By using the variational iteration theory, the approximate expansion of the solution of the model is simply obtained. By comparing with the exact solution of the model in a special case, the first approximation solution has the exact accuracy .
