( 6 ) this subject firstly brings up estuary sediment optimized control conception, and has the primary study on the macroscopically optimized control conception method
研究認為: ( 1 )黃河河口口門逕流潮汐區域並非持續保持淤積狀態,在特定的來水來沙、邊界條件和海洋動力條件下,該區域可以處于沖刷狀態; ( 2 )從河口泥沙沉積分配的過程來看:三角洲與濱海區泥沙的沉積變化趨勢是基本一致的,各部位的泥沙沉積比例變化基本呈波動狀態,且三角洲與濱海區泥沙的沉積比例與來沙量密切相關,基本成正比關系; ( 3 )在口門處,影響泥沙沉淤的因素主要集中在潮汐頂托、口門逐漸加寬、河口門分汊、鹽水造成絮凝等,本報告主要對口門加寬,口門西妥理工大學工程碩士專業學位論文分漢對河道淤積的影響進行了定量分析: (一扣根據實測資料首次建立了河贖流路泥沙沉積分配的回歸計算式,據此可以預估計算河口不同區域泥沙的沉淤量; 、 5 )本項研究首次論證了河口三角洲岸線動態平衡的概念,並建立了黃河河口來沙量與造陸面積的相關關系,得出了當河口多年平均來沙量維持在3 . 45億t時其河口三角洲岸線則可能處于動態平衡狀態的重要結論; 『 6 )本項研究首次提出了河口泥沙優化調控的概念,並對其宏觀優化調控模式進行了初步探討。This paper firstly introduces the phylogeny and actuality of tide - power stations ; the development style of them ; and then, establishes the mathematics model of optimal regulation of tide - power stations ; narrates how to use eq, dynamic programming, genetic algorithm to solve the problem of optimal regulation of tide - power stations individually ; makes comparison of three kinds of methods, pointing out the excellence and weakness of each method ; discusses some particular problems of tide - power stations, differing from normal water power stations. besides, this paper uses vb to develop an optimal regulation software which can be used in all tide - power stations
本論文首先介紹了世界潮汐電站的發展史及發展現狀;潮汐電站的建庫方案;然後建立潮汐電站廠內經濟運行和短期優化調度的數學模型;在此基礎上,進一步使用等微增率法、動態規劃法和基因遺傳演算法來求解潮汐電站優化調度問題,並對三種方法作了比較,指出各自的優缺點;論文也探討了潮汐電站優化調度中不同於常規水電站優化調度的特殊問題的處理方法。After validating the good agreement between simulated results and observed ones, the characteristics and the distribution rules of tides and tidal currents in the whole seas near to zhejiang are thoroughly analyzed, mainly based on the simulated results, combining with the observed conclusion. the co - tidal and co - range charts, co - current charts, types of tides and tidal currents, distribution of maximum possible tidal range and maximum possible tidal current, phenomenon of diurnal inequality, moving modes of tidal currents, tidal ellipses, distribution of tidal residual currents and the vertical structure of tidal currents and residual currents are investigated respectively. and thereout we draw a series of meaningful conclusions as follows, the main of these are : 1
在驗證模擬與實測符合良好的基礎上,本文以模擬計算結果為主,結合實測資料的分析結論,對整個浙江近海的潮汐、潮流特徵和分佈規律作了全面、深入的探討,分別對各主要分潮的潮汐同潮圖、潮流同潮圖、潮汐性質、潮流性質、最大可能潮差分佈、潮汐日不等現象、最大可能流速分佈、潮流的運動形式、潮流橢圓、余流分佈以及潮流和余流的垂向結構等進行了研究,並由此得到了一系列有意義的結論。Internal waves are a kind of bridge relating the diapycnal mechanical mixing to external sources of mechanical energy : first, internal waves are driven by wind stress and barotropic tide so that large amount of mechanical energy are transported to abyssal ocean with propagation of internal waves ; second, the mechanical energy can directly be cascaded to mixing through instability and breaking of internal waves
內波是外界提供的機械能與混合之間聯系的橋梁之一,一方面風和潮汐通過激發內波,將能量向深海和大洋內區傳遞,另一方面,內波的不穩定和破碎直接將機械能串級到小尺度湍流混合中去。開展傾斜地形上內波的傳播以及內潮的產生等方面的研究對海洋混合過程的參數化以及混合對大洋環流的影響等方面的研究具有重要的科學意義。The main channel of shing mun river was slightly better, graded fair, but it suffered from the pollution load coming from its tributaries, and its self - cleansing capabilities were limited due to its very weak flow in the intertidal area
城門河主河道的情況稍好,水質等級為普通,但因受到支流污染物的影響,加上潮汐水流緩慢,凈化能力不足,因此當時城門河裡幾乎沒有水生物棲息。The geomechanics based on the change of rotating speed of the earth could answer a large part of the above mentioned questions, but the power which it depends on offered by the expansion or contract of the earth and tides et al is too weak to serve as the energy to change the rotating speed of the earth, so it is also difficult to explain them quantitatively
基於地球自轉速度變化的地質力學理論,對之所做的定性解釋頗為合理,但因其只靠地球收縮及潮汐引力等緩變力作為引起地球自轉速度變化的動力來源,力量強度太小,不足以引發強大的褶皺造山運動,且有被海水運動取代的難題。分享友人
