The sensitivity analysis shows that the express shipping service will be more necessary when the average value of shipping freight in the market increases
而當航線貨運市場中，高時間價值貨種的貨櫃量占總貨櫃量的比率愈高時，海運公司提供復合快速運送的市場利基愈大，可訂定的海運差別定價愈高。The thesis analyzed the present transferring status between pudong airport and shanghai " s incity. through forecasting the long - dated flux of pudong airport and the area near it and combining the planning scheme of shanghai urban rapid mass transit, the thesis learned the helpful experience of the traffic organization in typical airport abroad and used the scientific analyzing model of public traffic flux forecasting to put forward some reasonable suggestion of the bottleneck question between pudong airport and incity : the one is to use the present no. 2 subway as the future airtrain to take on the most part of the flux and meantime present the concept of feeder efficiency to quantitative analyze the choice of feeder station ; the other is to set up cat ( city air terminal ) to convenient the passenger to come airport rapidly and economically in order to lessen the pressure of the traffic and improve the whole service quantity of civil aviation transportation
本文分析了浦東機場與市內目前的換乘現狀，從預測浦東機場及緊鄰空港區域中遠期的客流量入手，結合上海市政府快速軌道交通的規劃方案，並且學習境外典型機場交通組織的有益經驗，利用規劃中的公交客流預測等科學分析模型，對浦東機場與市中心的軌道交通銜接提出了合理的建議：一是利用目前的地鐵二號線作為航空軌道共享線來承擔大部分進出空港的客流，並且給出了以接運效率最大化為目標函數的接運公交軌道站點比選模型；二是在市中心設立城市航站樓以方便旅客快速、經濟地到達機場，從而減少道路交通壓力，提高航空運輸的整體服務質量。For marine salvage, speedy and effective towing with cable can enhance the rescue efficiency
摘要海上救助中，快速有效的帶纜拖航可以提高救助效率。On the other hand, as ship ' s number, speed, displacement is increasing and shipping density improving, the probability of shipping accident is rising. as a result, the number of wrecking ship accounts for 0. 4 percent of the whole world ship fleet, and 40 percent of the accident are correlated with the maneuverability
另外，船舶數量增多，航速提高，噸位增加，航道中航行密度加大，海損事故概率上升，每年失事的船舶約佔世界船隊的0 . 4 ，其中與操縱有關的事故佔40左右。By means of the sea trial, it is verified that at full loading condition of 12. 5m draught, the vessel ' s speed attained to 15. 09 knots with the rotate speed of 100. 5rpm, at the condition of the sea margin of 15 % and rotate speed margin of 5 % at csr of main engine
Sin ） ，主機正常功率帶有15的海上裕度和5轉速裕度時，航速為15刀9節，轉速100 5pm ，與設計吻合。最後，本文進行了滬東型（ hd ）螺旋槳的系列研究。It has been proved by lots of examples we can improve greatly our work efficiency and service quality by integrating advanced it methods into engineering areas. for vessel traffic services ( vts ), though it has used some new technologies to improve its efficiency and service quality, advanced it methods still should be employed into its daily maritime management to promote vts working level
對于vts系統來說，從最早的導航燈塔開始，多年來雖然運用了一些較為先進的工程技術提高了管理效率和服務質量，但是隨著海事交通運輸量的增加和計算機網路技術的快速發展，對vts系統進行進一步的改進，在日常海事管理服務中運用先進的計算機網路技術提高其信息化和網路化程度，已經成為大勢所趨。Shiphandling simulator is a device that can partly imitate the true environment at sea ， and is specially designed to satisfy marine education and trains and maritime research etc. one of its key techniques is to create the virtual environment at sea ， and the terrain is its important component. according to the needs of the real time visual display of the shiphandling simulator ， this paper analyses the requirements of the geometry precision of the important islands and background hills which are within the ships ' visible scope ， and brings forward the modeling methods of the hill ' s pileup and the hill ' s silhouette edges based on contour lines. it also presents the definition of error that the hill ' s silhouette edges graph has been given and the effective scope of application ， and firstly established the error criterion of terrain model that is built in shiphandling simulator. with these two kinds of method ， the size of data storage can be minimized greatly ， and the requirements of high update rate and geometry precision for the real time visual display of the shiphandling simulator can be satisfied
船舶操縱模擬器是一種能夠部分模仿海上真實情況，專門為滿足航海教育與培訓、航海技術研究等目的而設計研製的裝置，其核心技術之一是海上視景模擬，而地形地貌是海上視景中的重要組成部分.根據船舶操縱模擬器實時視景顯示的需要，在分析航行船舶對可視范圍內重要島嶼與背景山脈的幾何精度要求的基礎上，提出了基於等高線的山形堆積建模和山形輪廓建模方法，並給出了山形輪廓圖形的誤差定義、有效適用范圍，以及船舶操縱模擬器中地形建模的誤差準則，該方法生成圖形的數據量較小，其圖形更新速率與幾何精度能達到船舶操縱模擬器實時視景顯示的要求分享友人
