  1. The results indicated that the generation of trailing - vortex of downstream adjacent vanes could be restrained effectively by upstream wake when the passing frequency and the amplitude of wake defect satisfy some conditions, associated with a significant enhancement of time - averaged aerodynamic performances : loss coefficient reducing 40. 2 % and the ratio of loading coefficient and loss coefficient increasing 93 %

    研究表明：滿足一定通過頻率和虧損幅值條件的尾跡能夠有效抑制下游相鄰葉排尾緣渦的生成，達到控制或是推遲附面層非定常分離的目的，從而使得流場時均性能大幅度的提高，損失系數降低了40 . 2 % ，功損比增加93 % 。
  2. Low - amplitude events by themselves are not significant

    低烈度事件本身並不引人注目。
  3. High - amplitude events are very destructive and significant

    高烈度事件具有相當的破壞性且十分重大。
  4. Secondly the detection precision is only related to the synchronization phase but not to the amplitude of the mainline voltage because that it uses the optimized pulses synchronous with the mainline voltage as modulation signals. thirdly it decreases the requirement of the input low pass filter and eliminates the error resulting from the direct component and even harmonics of load current. the most significant merit is that it can eliminate the effect of a few low order odd harmonics and the detecting circuit is easy to be implemented

    模擬和實驗結果表明該方法的主要優點有：不需使用乘法器進行信號調制，調制信號採用與電網電壓同步的優化特定脈沖，其檢測精度只與同步相位有關，而與電網電壓幅值無關；降低了對輸入低通濾波器的通頻帶要求，直流和偶次諧波分量對檢測精度沒有影響；突出的優點是可以消除有限個低奇次諧波對檢測結果的影響。
  5. In the four parameters the frequency of excitation force is most significant to the horizontal and vertical velocity of seedlings. the amplitude of excitation force is less significant

    四個因子中，頻率對缽苗的推送速度影響最為顯著，其次是激振力幅值f 。
  6. So power systems harmonic analysis is a significant aspect of power systems research. power system harmonic analysis was realized usually with fast fourier transform ( fft ), but the method exits spectrum leakage, and can not analyse all harmonic parameters exactly, such as frequency, amplitude and phase, in particular has big phase error

    電力系統諧波分析通常都是通過快速傅立葉變換（ fft ）實現的，但是這種方法存在柵欄效應和頻譜泄漏，使計算出的諧波參數即頻率、幅值和相位不準，尤其是相位誤差很大，無法滿足準確的諧波測量要求。
  7. The larger the phase - shift, the more significant the amplitude of soliton pulse descended

    相位漂移越大，孤子幅度下降越顯著。
