Abstract : the biological control effect on fruit tree insects and eco - economic benefit of interplanting mentha spicata with orchard was studied and analysed based on field polt experiment. the result shows : interplanting mentha spicata with orchard have obviously biological control effect on fruit tree insects like phyuoenistis eitrella stainton, papilio xuthus l, phyllocoptruta oleivora ashmead and myzus perieas sulzer ect, interphanting mentha spicata with slope orchard could reduce soil and water losses, and improve soil physical - chemistry property effectively, its also accelerate fruit tree growth and increase the yield of fruit tree, and has good economic benefit
文摘:在野外小區試驗的基礎上，對果園套種留蘭香生物防治果樹蟲害的作用及其生態經濟效益進行了研究和分析，結果表明：果園套種留蘭香對潛葉蛾、柑橘鳳蝶和桃蚜等果樹害蟲有明顯的生物防治效果；在坡地果園套種留蘭香能有效減輕水土流失、改善土壤的理化性狀，促使果樹的生長和提高果樹的產量，並具有良好的經濟效益In chapter four, according to the analysis on the boundary theory and velocity field of main fluid zone of two - phase fluid pumps, the parameter equations of vane ' s modular curve of centrifugal pump are given, which contact the boundary " layer and eular theory of two - phase fluid pump by the fixing angel of vane as variable and leading into the velocity coefficient a. the results show that, in designing process of vane ' s modular curve of centrifugal pump, the determination of the total shape and parameters relates the flow properties of two - phase fluid and output ability of pump, or the design of the modular curve of centrifugal pump is the kernel of hydraulic design
第四章依據固液兩相流泵的邊界層理論及對主流區速度場的分析，給出了離心泵葉片型線的參數方程；它是以葉片安裝角為參變數，以引入的速度系數k _ v作為中間因子，將兩相流泵的邊界層理論和歐拉理論聯系起來? ?它說明了這樣一個事實，在離心泵葉片型線的設計過程中，它的整個形態或參數的確定都關繫到兩相流體的流動特性和泵的輸出能力，或者說，離心泵型線的設計是其水力設計的核心。Works well - designed, skillfully carved italian, a lifelike sculpture garden, vivid detail, it may play in the water chasing gloria, the sweet murmur distinctive appearance, is the envy of people, the two lovers are distributed back a little green and white, more exquisitely charming, op using the above comes the meticulous carvings attendants the beautifully atmospheric leaves, the delicate vein smooth, crafted natural that comes to the distribution attendants reasonable superb, the leaves among the cleverest black jade carved out of two removable small lifelike frogs, picked clean natural colors, more vivid realism

本作品河床，以大河孕育文化做為作品創作發想點，加入現代社會的生活休憩概念，將五組象徵大自然中河川交匯的床型花崗巖雕塑，架設于卵石所鋪設而成的基隆河之上基隆河的河道造型則保持截彎取直前的原貌，並以少流量的水流，薄薄地覆蓋五組床型雕塑品，床板上散落的楓葉與果實，則象徵環保理念對大自然保育的重要性。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部化性質，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尾水渦帶擺動是引起定子基礎振動的主要原因。The repair and maintenance work of the turbine blades is the international problem for all the hydro power plant. a lot of manpower and resources is costed every year, especially in china, because the rivers contain plentiful sand, the problem is more serious
