  1. Through the deep study of f. d. demello dynamic model of electromechanical transition and synchronous generator theory, we proposed a new control strategy of excitation device that can eliminate the negative - damping phenomenon, which is directly against the cause of producing negative - damping represented as low frequency oscillation in the system

    通過深入研究f . d . demello機電暫態的動力學模型以及同步發電機理論，針對系統產生負阻尼即低頻振蕩的原因，我們提出了一種新的可消除負阻尼現象的勵磁控制策略。
  2. Calculations indicate that the carrier phase takes effect till the time width of the pulse envelope becomes smaller than the period of the carrier oscillation, and the interpretation of this phenomenon is also presented. it is the difference between phase delay and group delay that causes the sliding between the carrier and the envelope

    數值分析的結果表明，當脈寬小於光波周期時，相位的作用開始顯現出來，當脈寬比光波周期長時，載波相位的作用可以忽略，並分析了相位起作用的原因，用解析的方法說明正是相延遲和群延遲之間的差別造成了光載波在脈沖包絡下的滑動。
  3. A phenomenon called self - induction is at work here : as the current oscillates, the magnetic field around the wire changes, too, inducing voltages that slow the oscillation

    這里運用了一種自感現象：當電流振?時，金屬線周圍的磁場也會改變，產生使振?減慢的電壓。
  4. Tthe quasi - biennial oscillation, an oscillating phenomenon in which the wind in the upper atmosphere over the tropics changes its direction from east to west and then back to east about every two years

    準兩年振蕩發生在赤道附近的高空，分為西風異常和東風異常兩個交替出現的位相，周期約為兩年。
  5. In addition the h. kantz method is applied to analyze the time series of the motor current, the maximal lyapunov exponent calculation is realized, the criterion for the motor chaos is brought forward, the existence of chaotic phenomenon in the induction motor is verified by the characteristic exponents, which proves theoretically that the chaotic movement is one of the reasons that results in the low frequency oscillation of the induction motor system

    應用h . kantz方法對電機電流信號的時間序列分析，實現了最大李亞普諾夫指數的具體演算法，提出了電機出現混沌運動的判定根據，通過特徵指數驗證了異步電動機現象的存在，從理論上說明混沌運動是異步電動機系統產生低頻振蕩的原因之一。第三部分深入研究了系統低頻振蕩的主要影響因素。
  6. The influence of the blowing factors to the flutter and the lift coefficient is analyzed. secondly, the self - induced vibration of seals are analyzed by fluid - structure coupling numerical method. the self - induced oscillation of the seals will occur at large rotational speed, however, this phenomenon ca n ' t be simulated with the

    採用本文的流固耦合方法成功地捕捉到頻率鎖定的現象，且發現隨著轉速的提高，固有頻率也增大，從而證明高轉速下密封轉子會發生自激振動，傳統的剛度阻尼方法對此是無法解釋的。
  7. Abstract : the system of the pyrotechnic oscillation burning ha ve been studied with the experimental research and the reaction mechanism analys is methods. the phenomenon of the oscillation burning has been observed and reco rded, and the relationship of the concentration of the reactant with the frequen cy of the oscillation has been obtained

    文摘:對具有振蕩燃燒現象的體系進行了實驗研究和反應機理分析；對振蕩燃燒現象進行了觀察和記錄，得到了各反應物與振蕩燃燒現象的關系。
