The low-frequency fluctuation periods and the initial amplitudes have close relationship in the resonanceinteraction.
三波共振相互作用低频振荡周期与初始扰动振幅有很强的相关关系；

The resonanceinteraction of plasma waves with the toroidal drifts of particles leads to the occurrence of a class of the So-Called "resonance integrals".
等离子体波与粒子的环形漂移共振作用，导致一类所谓的“共振积分”。

Applying the modified extended tanh-function methods, many types of new explicit traveling wave solutions of the (2 + 1) dimensional long wave-short wave resonanceinteraction equations are obtained.
