Analyzing the physics structure of vorticity, divergence, vertical velocity, frontogenesis " function, apparent heat source and apparent moist sink etc. indicated the physics fields are favorable for the occurance of the heavy rain over changjiang - huaihe river basin where the physics values are well according to the heavy rainstorm positions ; the low level jet is closely subject to the moisture and the coupled system of the low and the upper level jetstreams induced the strongly " ascending motion ; the intensity of the frontogenesis varies with the development of the rainfall system and reacts the rainfall intensity
主要分析了這次過程中的多種物理量,包括渦度、散度、垂直速度、鋒生函數、視熱源、視水汽匯等,對這一暴雨過程有了比較系統的認識。結果表明:在江淮流域存在著有利於發生暴雨的物理量場配置,渦度、散度、垂直速度等物理量,與暴雨的落區都很吻合的;低空急流的產生不僅有利於水汽的輸送,而且高低空急流的耦合造成了有利於強上升運動的配置;鋒生強度隨著降水系統的發展變化,並影響降水強度。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。Do not swim in where the water is swirling around ; there are dangerous currents
不要在有漩渦的水域游泳,那裡有危險的暗流。A warm water current within it swirls clockwise, affecting the weather of the area, keeping it calm and steamy
在它裏面暖流漩渦成順時針旋轉,影響了該區域的天氣,使藻海平靜和水汽彌漫。A spiral motion of fluid within a limited area, especially a whirling mass of water or air that sucks everything near it toward its center
漩渦在一定地域內液體的螺旋狀運動,尤指把附近各種東西吸向其中心的螺旋水流或空氣While the precipitation of southeast of inner - mogolio is attributed as the strong convective precipitation, the rainfall of liaoning and northeast of heilongjiang is induced by subtropical high and westerly trough, and that of west of heilongjiang is influenced directly by vortex in upper air
各區域產生極端降水的天氣背景也不相同:內蒙古東南部的降水是前傾槽引起的強對流降水天氣,遼寧和黑龍江東北部的降水是由於副熱帶高壓和西風槽的共同作用引起的。黑龍江西部的降水是由於高空渦的直接作用引起的。分享友人
