We give a center manifold theorem in the neighbourhood of the equilibrium point, and prove that the center manifold is exponentiallydecaying.
在此平衡点附近建立中心流形定理，并证明中心流形有空间指数衰减性。

They have globally asymptotic stability, and can forget the effect of the initial state estimates at an exponentiallydecaying rate by assigning the poles of the estimators.
它们具有全局渐近稳定性，且通过配置估值器的极点可按指数衰减速率使初始状态估值的影响快速消失。

In spectral resolution enhancement the linear prediction of exponentiallydecaying sinusoidal superposition signal is one of the key technologies.
