  1. Periodic waves marker

    周期波時標
  2. From some characteristics observed, such as the short lift time, narrow frequency band, fast frequency drift, quasi - periodic pulsation, spike event and complex magnetic structure, it is considered that the radiation mechanism of these events may be principally due to the electromagnetic waves magnified directly by the instable electronic cyclotron

    從它們的觀測特徵：短壽命，窄頻帶，頻率快速漂移，及尖峰事件與磁結構復雜的大黑子活動區密切相關等，認為這些事件的輻射機制可能是電子迴旋脈澤不穩定直接放大電磁波所致。

  5. We consider the traveling waves of a delay cnn system with the output function f given as a non - linear function in the latter. we show the existence of monotone traveling waves solutions and describe the global structure of traveling waves such as monotone, damped oscillation, periodic oscillation and unbounded etc as the wave speed c is classified in r

    第二部分我們考慮具時滯非線性cnn系統模型，得出方程單調行波解存在，並將波速c r分成若干個區間，得出c在各個區間時行波解曲線相應的類型包括單調、衰減振動、周期振動、無界等類型。
  6. Firstly, acoustic waves propagation in id quasi - periodic system is studied by means of the transfer matrix method. the transmission rate, reflection rate, energy flow, logarithmic energy flow, energy density and lyapunov exponent are obtained numerically. we explain all these parameters " relations with frequency and the size of system, and compare these p arameters with those o f periodic system. we find that these parameters are fractal in this quasi - period system

    通過轉移矩陣的方法，數值地得到了系統的傳播系數t _ n 、反射系數r _ n ，能流密度j _ n 、能量密度e _ n 、李雅譜諾大指數_ n ，給出了以上各量與系統大小n以及頻率之間的關系，發現這些量存在著與周期系統不同的準周期性質，其能量會出現局域化現象，能流以及能量密度都具有分形結構，給出了相應的理論解釋。
