The power spectrum of white noise and the diagnosis of work conditions in the random process
隨機過程的白噪聲功率譜及工況診斷By solving the stochastic differential equations describing the noise performance of the cmos gilbert mixer, the time - varying power spectral density of its output noise at high frequencies is given
通過求解描述cmosgilbert型混頻器噪聲性能的隨機微分方程，本文給出了該類型混頻器高頻輸出噪聲的時變功率譜密度。Then analytical measurements of the noise were carried out on both of the turbines by means of modern acoustic apparatus and a conclusion has been found that the noise of the concentrated wind energy turbine is lower than the one of the ordinary wind energy turbine and the root of the trouble to cause noise chiefly originates from the turbine blade. besides, the result of analytical measurement also reveals that the power output both of the wind energy turbines will increase with the increase of the wind speed and unfortunately does the noise too. in order to lower the noise, a measures of noise reduction have been advanced that an active method is to develop a wind energy turbine run at a lower rating of wind speed while the passive method is to adopt a board drilled tiny holes, having established a sound technological basis for the development of a kind of wind energy turbine of low noise and high level in the world
主要對濃縮風能型風力發電機在正常運轉時，噪聲產生的機理進行了理論分析研究，並與普通型風力發電機的噪聲進行了對比實驗分析；利用現代聲學測試手段對兩類機型進行測試與分析，得出濃縮風能型風力發電機產生噪聲低於普通型風力發電機和葉輪是風力發電機產生噪聲的主要部件的結論；通過對兩類機型的噪聲、輸出功率的測試，得出隨著風速的增加，兩類風力發電機的輸出功率在增加，產生的噪聲也在增加的結論；提出了進一步降低濃縮風能型風力發電機噪聲的措施，從主動降噪方面，研製低額定轉速的發電機；從被動降噪方面，採用微孔穿板的降噪結構；為研究開發一種國際上低噪聲、高水平的風力發電機打下了良好的技術基礎。Its power spectrum is similar to gauss white noise. the similar random correlativity is good
