  1. Thus, it is difficult to find the voltage reference for the harmonic analysis. since acem are always operated near to the synchronous speed, the frequency of the excited voltage is very low, even to zero. therefore, this is the power harmonic suppression study of a complicated power supply system, in which the about harmonic general theories and methods are all inapplicable

    現代交流勵磁電機( acem )採用電力電子變流作為勵磁裝置,其勵磁電壓諧波含量豐富,難于獲得諧波分析所需的電壓基,同時交流勵磁電機經常工作在同步轉速附近,致使勵磁電壓頻率極低甚至為流,通常的諧波檢方法和理論都無法適用,因而這是一種目前尚未深入討過的復雜供用電系統電力諧波抑制問題的研究。
  2. The authors have developed a device for measuring the normalized difference vegetation index ( ndvi ) by using four specially designed photoelectric detectors ; the ndvi can reflect the growing information and seasonal nitrogen fertilizer requirement of crops, and offers guidance for rational application of nitrogen fertilization

    文中提出了一種由4個專門設計的光電接得到歸一化植被指數的量方法,該參數能夠反映作物的生長狀態,知道不同季節的農作物對氮的需求量,對實施變量精施肥具有重要的指導作用。
