  2. 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

    摘要基於李家峽水電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 )對于非穩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的局部化性,通過對開停機這一典型非穩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,並對其作振源分析,得出開停機初始時刻因水流不穩出現強烈的振動現象,且低頻段信號能最大,開停機過程水流脈動壓力和尾水渦帶擺動是引起定子基礎振動的主要原因。
  3. At the initial stage of planar technique, b was employed as ideal diffusion impurity in base - region of npn si planar devices because of the match of its solid - solubility and diffusion coefficient in si with those of p in emission - region, and the good shield effect of sio2 film to b. but because of the relatively large solubility ( 5 1020 / cm3 at 1000 ) and the small diffusion coefficient, the linear slowly - changed distribution of acceptor b in pn junction can not be formed, which could not cater to the requirement of high - reversal - voltage devics. thereafter b - a1 paste - layer diffusion technology and close - tube ga - diffusion technology had been developed, while the former can lead to relatively large the base - region deviation and abruptly varied region in si, which caused severe decentralization of current amplification parameter, bad thermal stability and high tr ; the latter needed the relatively difficult pack technique, with poor repeatability, high rejection ratio, and poor diffusion quality and productio n efficiency

    面工藝初期,由於b在硅中的固溶度、擴散系數與n型發射區的磷相匹配, sio _ 2對其又有的掩蔽作用,早被選為npn硅面器件的理想基區擴散源,但b在硅中的固溶度大( 1000時達到5 10 ~ ( 20 ) ,擴散系數小, b在硅中的雜分佈不易形成pn結中雜的線性緩變分佈,導致器件不能滿足高反壓的要求,隨之又出現了硼鋁塗層擴散工藝和閉管擴鎵工藝,前者會引起較大的基區偏差,雜在硅內存在突變區域,導致放大系數分散嚴重,下降時間t _ f值較高,熱穩定性差;後者需要難度較大的真空封管技術,工藝重復性差,報廢率高,在擴散、生產效率諸方面不能令人滿意。
  4. To control the quality of tpi, rp - hplc was used to determine the content of propanoic acid and proto - catechuic aldehyde in it. the results show that the average recovery rate was 98. 01 %, 97. 43 % and rsd = 2. 75 %, 2. 83 % respectively. this method is simple, accurate with strong reproducibility, and can be used for the quality control of danshen in any other compounded medications
