  1. In light of the limitation of fast fourier transform ( fft ) for the method of traditional spectrum analysis to analyze the unsteady signal, wavelet and wavelet analysis are made for the typical unsteady process signal of starting up and shut down with the good characteristic of simultaneous localization in both the time and the frequency domains based on the field test on the vibration of two - row placed units in lijiaxia hydropower station, in which the signal is decomposed into different frequency band, and then the weak signal is caught and the dominant frequency is picked up for the analysis of the vibration source

    摘要基於李家峽水站雙排機組振動的現場試驗研究,並且針對傳統頻譜分析方法傅立葉變換( fft )對于信號已力不從心這一缺陷,利用小波分析方法在時域和頻域上同時具有良好的局部化性質,通過對開停機這一典型過程信號進行小波及小波包分析,將其分解到不同頻帶內,獲取微弱信息和提取優勢頻率,並對其作振分析,得出開停機初始時刻因水流不均出現強烈的振動現象,且低頻段信號能量最大,開停機過程水流脈動力和尾水渦帶擺動是引起定子基礎振動的主要原因。
  2. It use new materials that making the resistance of the battery less, and it also use the up - to - date technology, so that making the battery have such lodging characters. consequently, alkali - manganese battery will be using broadly in the future

    堿錳池是當代新型的高能池,它具有容量大、放時間長、放等特點,故而是較高檔次又應用常廣泛的化學
  3. In this circuit, reference current sources are used to charge and discharge capacitors. this oscillator ’ s output is very ideal through control circuit under 5. 7v reference voltage, and oscillator ’ s frequency and duty - cycle could be adjusted if reference current source or capacitors in the circuit was adjusted. and the changes of temperature and voltage affect stabilize of the frequency little

    路利用系統內部基準產生的流信號來對容進行充放,然後經過控制路作用后,產生的輸出振蕩波形的上升時間和下降時間常小,更接近理想矩形波形;通過調節基準流信號或者容值大小,可調節振蕩波形的頻率和占空比,同時溫度和的變化對振蕩器輸出波形頻率定度的影響很小。
