  3. Niche breadth of four dominate populations at three age groups was studied by the methods of resource utilization ability and ratio. the result shows that : symplocos sectchuanensis is a typical gengeration species whi ch resource utilization ability is strong, and distribution is wide. meanwhile, go rdonia acuminata, castanopsis fargesis and pinus massoniana specialized at some d egree in resource utilizationm, their distribution is limited. especially, the ju venile of pinus massoniana specialized outstandingly. with the devlopment of pinu s massoniana, which is the pioneer population in mt. jinyun, the environment become s unfit to it ' s juvenile. it turns to needle and evergreen broad - leaves mixed fo r est. because the tolerance toward shading of gordonia acuminata is lower than tha t of castanopsis fargesis, gordonia acuminata will be substituted by castanopsis fargesis and other evergreen broad - leaves species are the edificators. the popul ation ' s ability of resource utilization is the inner factor of population distri bution and community succession. the distribution of light and the concentrate of nutrient ( such as n ) is the outer factors of community succession

    對縉雲山森林植被的4個優勢種群3個年齡級生態位寬度進行了研究.結果表明,川灰木利用資源的能力最強、分佈廣,為典型的泛化種.大頭茶、栲樹、馬松對資源的利用在一定程度上特化,分佈上有一定的局限性.馬松的中齡組與幼齡組特化現象十分顯著.縉雲山森林植被的先鋒種馬松的發展,導致環境的改變不適于其幼齡個體的生長,群落演替到闊葉混交林階段,最後發展為以栲樹等為建群種的常綠闊葉林.種群的資源利用能力,是種群分佈與群落演替的內在原因,光因子和營養元素(如n )是群落演替的主要外動力
  4. 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,並且對傳統頻譜分析方法傅立葉變換( fft )對于非平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良好的局化性質,通過對開停機這一典型非平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壓力和水渦帶擺動是引起定子基礎振動的主要原因。
