  1. In this paper periodically perturbed hopf bifurcation to lienard equation with limited time delay is sdudied in detail. that is, the influence of small periodic perturbations on system exhibiting hopf bifurcation is sdudied. in particular, the excitation frequency and the critical natural frequency of hopf bifurcation in the cases of harmonic resonance. subharmonic resonance, ultraharmonic resonance, and ultrasubharmonic resonance is discussed. it is shown that in some parameter regions the sestyms exhibit harmonic solution bifurcation, subharmonic solution bifurcation, ultraharmonic solution bifurcation, ultrasubharmonic solution bifurcation and quasi - periodic solution

    本文詳細研究了具有限時滯li nard方程的周期擾動hopf分支,即在該系統經歷hopf分支時,研究小周期擾動對系統的影響,特別是討論了擾動頻率與hopf分支周期解的固有頻率在共振、次調和共振、超調和共振、超次調和共振的情形。
  2. The tree of this paper is as follows : in chapter 2, we study the uniformly asymptotic stability of the trivial solutions of a class of linear and nonlinear difference - differential equations with finite time - dependent delays. then, we deal with the existence, the uniqueness and the stability of periodic solutions and almost periodic solutions when the systems are under periodic perturbations and almost periodic perturbations

    本文內容具體安排如下:第二章,我們首先研究一類具有限變時滯的線性及非線性差分微分方程系統的零解的一致漸近穩定性,然後討論在周期擾動和概周期擾動下,相應系統的周期解和概周期解的存在唯一性及穩定性。
  3. In this paper, the chaotic motion of a planar 2r robot is controlled successfully based on the method of periodic signal perturbations for the first time

    摘要本文通過外加周期信號擾動系統參數的方法以平面2r機器人為例首次對機器人機構中的混沌運動進行了成功的控制。
