Study achievement appears as following aspects : ( 1 ) yellow river estuary gate river flow and tide flow mixed area is not keep standing deposition status, on special income water and sediment conditions, boundary conditions and oceanic power conditions, this area may on the scour status ; ( 2 ) observed from estuary sediment deposition distributing process : delta and sea offing area sediment deposition vary trend is similar, each part sediment deposition scale varies as wave shape ; ( 3 ) on estuary gate, affect the sediment deposition factors, primary factors are tide prop, the gate widens gradually, estuary gate have branches, brine induced flocculation. this paper study the estuary gate widen, estuary gate have branches to affect the river channel deposition in quantity ; ( 4 ) based on field measured data, for the first time, deduce the estuary sediment deposition and distributing regress formula which can estimate estuary different areas sediment deposition volume ; ( 5 ) this subject demonstrate the estuary delta coastline dynamic balance conception, build the relationship between the estuary income sediment with deposition land area, draw the following important conclusion : when estuary years - averaged income sediment keeps at 345 million tons, the delta coastline may on the dynamic balance status. ( 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。Hf radar can measure the sea surface parameters. on oceanography, hf radar can be used in researching the property of ocean wave, supervising the sea status timely, getting offshore wind field picture as well
它在海洋學上可用於研究海浪性質,能實時監測海況而服務于航海業、海洋工程、海洋警戒、海洋漁業和海洋平臺作業等,還能獲取氣象預報中所需要的海面風場圖。As a result, the studying aim of this paper is to establish a practical and complete system for the prediction of ship maneuvering motion, taking into account of the influence of the environmental factors, such as the wind, wave and current, establish a practical and complete system for the prediction of ship maneuvering motion. in this paper, the opengl virtual reality simulation technique is introduced into the field of ship maneuver and control, and using the mmg mathematical model, the three dimensional dynamic simulation system of the ship motion is established and good results are achieved. in the process of the system development, firstly, the maneuvering motion equations for ship in the still water are established, based on the mmg module mathematical model and serial experimental result
在系統開發過程中,首先採用mmg分離式數學模型及相關的系列化試驗結果,建立單槳單舵海洋運輸船舶在靜水中的船舶操縱運動方程,並編制計算程序,經與試驗結果比較,證實了計算結果的正確性;為了解mmg數學模型中模型參數變化對操縱性指數的影響程度,作者在上述已有程序基礎上,對有關模型參數進行偏移修正,探討了相應參數變化后的操縱性指數,對船舶操縱性指數對模型參數的靈敏度進行了詳細的分析與探討,所得結論與工程實際相吻合,具有實際應用價值,並為進一步提高船舶操縱性預報的精度打下了基礎;然後,在已有的船舶靜水操縱運動模型基礎上,考慮雙槳雙舵的影響,建立了內河雙槳雙舵船舶的操縱運動模型;最後,綜合考慮風浪流作用力的影響,進行了船舶的操縱運動模擬計算。Upon using an artificial neural network ( ann ) a new short - term climate forecast model with the monthly mean rainfall in june in the north of guangxi as predictand is established making empirical orthogonal functions ( eof ) to the 36 predictors ( 15 ssa predictors, 21 500hpa height predictors ) with over 0. 05 significant correlation level of previous 500hpa height and sea surface temperature ( sst ) field, and selecting the high relative principal components, at the same time, a new approach of constructing ann learning matrix is developed. predictive capability between the new model ( principal components ann model ) and linear regression model for the same predictors is discussed based on the independent samples and historical samples
