Then the behavior of the free joint when we bring the periodic perturbation through controlling the actuated joint is analysed, we can find in the result that the behavior of the free joint in the phase plane follows an ordered closed trajectory with the center equilibrium point + 2 in the case where the amplitude of the input is small, we can define a weakening factor to make the position of the free joint reach the center equilibrium point + 2
通過相平面分析的方法分析了當驅動臂施加周期擾動對非驅動臂運動的影響，其結論為通過調整驅動臂周期擾動的幅度及極性，可以使非驅動臂沿著圍繞平衡點2的極限環軌跡運動。在此基礎上，提出衰減因子的概念，通過衰減因子調整驅動臂擾動的幅度和周期，使非驅動臂能夠穩定在平衡點2 。 -

將驅動臂的運動作為非驅動臂的擾動，建立了非驅動臂的動態模型，利用動態方程有效的近似解法?平均法，對非驅動臂的動態模型進行簡化，得到近似的平均系統，通過模擬計算驗證了二者具有相同的動力學特性。 -
It is only when the input to a region is synchronized with electrical activity occurring at the same time that you begin to distinguish simple, periodic waveforms in an eeg
只有當一個區域的輸入信號與其自身的腦電活動同步時，才能夠在eeg中區分出簡單、周期性的波形。 -
The suitable tree - like and 3 / 2curve fractal symmetrical vibrators are chosen to make up a log - periodic antenna ( lpda ), the performance, such as reflectance, input impedance, radiation pattern and gain are also compared with normal log - periodic antenna by cst microwave studio ? simulation, in order to investigate the effect of antenna miniaturization. the application of fractal technology in microstrip antenna is introduced at
最後本文介紹了分形技術在微帶天線中的應用，研究了minkovski分形雙層微帶天線的阻抗特性和方向圖特性，並與普通雙層微帶天線的性能進行比較，討論了minkovski分形對微帶天線尺寸的縮減作用，同樣研究了分形對交叉極化的影響。 -
For a long time, sr was described as a phenomenon wherein the response of a nonlinear system to a weak periodic input signal is optimized by the presence of a particular level of noise. however, this description has served to limit the application of sr to signal processing
但是到目前為止，隨機共振在信號處理中的應用的研究還只是局限在很小的范圍內，主要原因是以前大量的研究工作都從調節噪聲強度出發。 -
We take the peak current controlled dc / dc boost converter as an example. we compare and analyze power spectrum of input inductance current quantitatively of chaotic operation and periodic operation of converter. the computer simulation results demonstrate that power spectrum of input current has lower peak of power spectrum of chaotic operation than it of periodic operation, and then emi level is reduced
以一個峰值電流控制dc dcboost型變換器為研究對象，在分析電路混沌現象的基礎上，分別對該電路工作于混沌和周期兩種狀態下的輸入電流頻譜進行了定量分析對比，證實了在相同輸出電壓條件下，工作于混沌狀態下電路輸入電流的頻譜與工作于周期狀態下電路輸入電流的頻譜相比，頻譜峰值減小，具有降低emi水平的效果。
