在前人利用时滞自然振子方程研究赤道东太平洋海温演变特征的基础上，根据实际观测资料，反演获得了描述赤道东太平洋海温演变的时滞自然振子方程，并根据此自然振子方程初步研究了赤道东太平洋海温演化的非线性特征，获得了一些有意义的结论。
Based on the previous studies on the evolution of the SST in the equatorial eastern Pacific using the natural oscillator equation with time delay, the time-delay natural oscillator equation describing the evolution of SST in the eastern equatorial Pacific has been derived from the observed data. Based on this natural oscillator equation The nonlinear characteristics of the SSTA in the eastern equatorial Pacific have been preliminary studied and some meaningful conclusions have been obtained.
