small perturbation

A theorem of unchangeability of small perturbation and density of high matrix

高矩阵的小摄动不变性及稠密性定理

It is proved that when the filter is sufficiently excited the parameter and output error in the filter are asymptotically bounded if nowise perturbation is sufficiently small and the lower rate of convergence is used.

证明了，滤波器被充分激励时，如果噪声干扰足够小，且采用低自适应速率，滤波器的参数和输出误差是渐近有界的。

Based on the homeomorphous transformation for the model, it can be concluded that if the chaotic attractor for the diagonal is stable for the transverse small perturbation in neighborhood, it should be globally stable in the whole feasible set.

通过对模型的同胚变换可得到：如果对角线上的混沌吸引子在垂直于对角线方向上局部稳定，那么它在可行集的范围内也全局稳定。

一类条件稳定的多小参数奇摄动方程组边值问题

Based on the small perturbation and linearizing PH methods, the equations of the static and dynamic characteristics of three-pad-tilting bearing were deduced, and the numerical results were obtained on the sub-relaxing finite difference method.

运用小扰动法和线性PH的思想，采用有限差分亚松弛的数值方法求解了可倾瓦径向动压气体轴承单块瓦的静、动特性方程。
