  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. After the nonlinear and absorption effect is taken into account in the applications where high power ultrasonic is involved, the first and second harmonic components of the sound field of stepped circular plate is analyzed, based on the kzk equation and quasi - linear condition

    考慮到大功率超聲應用中的非線性和吸收作用,本文從kzk方程和準線性條件出發,對于工作在共振頻率下的這種階梯圓盤,推導了它的一階和二階諧波聲場計算方法。
