  1. This course is an introduction to principles of naval architecture, ship geometry, hydrostatics, calculation and drawing of curves of form

    本課程介紹船舶設計、船舶幾何、船舶流體靜力學、船體曲線計算與繪圖等科目的原理。
  2. When no damaged compartment, damaged stability calculation is just intact stability calculation and when waterplane is horiental, geometric properties calculation is the base of hydrostatic curves. because ship hull is a kind of typical free - form surface, it is satisfactory to be modeled with nurbs

    在這種情況下，船舶靜力學性能的計算，可以突破以往計算中所必須的一些假設及簡化，而是直接通過船舶靜力學性能計算的基本原理，在船體曲面圖形上直接進行計算。
  3. The lifting - line and lifting - surface design method, the harmonic analysis method based on the panel method, new section design ways, the effective operating curves are integrated into a whole design system of the unsteady propeller, the design system is effective and reliable by the design example, the model test and the application to the full scale ship

    本文把升力線和升力面設計方法、基於面元法預報螺旋槳非定常性能的諧調分析方法，新剖面設計方法、有效運轉曲線計算方法組合為一套完整的非均勻流場中螺旋槳設計計算系統，經實例設計和模型試驗及實船的應用，該設計系統是可靠且有效的。
  4. 2. based on continuous model and discrete model of control system, simulation technology is studied, finally curves about water level and journey of ship are drawn and probability of using is calculated

    提出了採用演繹法分別建立三峽五級船閘控制系統的連續模型和離散模型，並進行模擬研究，得到每個閘室的水位變化圖、船隻的行程圖以及船閘的利用率等指標。
  5. The added mass of the ship of three gorges project is also computed and the curves of the added mass coefficient via the different water domain are obtained. the results should be useful in practice and computer code could be used in relevant areas

    本文給出了船在有限域中運動時，隨有限水域尺寸的變化，附加質量系數的變化趨勢圖，為工程應用提供了參考，同時本文編制的程序可以直接計算各類相關工程問題。
  6. Considering the shortcomings in the genetic algorithms, some improvements are proposed in order to elucidate its strong optimizing ability, genetic algorithms are used to optimize the pid parameters of ship autopilot. the comparison between the different simulation curves shows the validity of genetic algorithms in looking for the best parameters

    本文首先用遺傳演算法來對船舶航向保持自動舵的pid控制參數進行在線優化，通過對用常規工程方法整定的pid控制和用遺傳演算法優化的pid控制的模擬曲線的比較，說明了遺傳演算法強的全局尋優能力。
  7. Because the shape of hull is very complicated and the curves and the surfaces have second order continuity, after many years of research and discussion. the appearance of b - spline brings the ship cad with a breakthrough, now, nurbs ( nonuniform rational b - spline ) becomes the most powerful fuction in hull cuve fitting and fairing

    由於船體外形復雜，並且船體外形曲線與曲面具有二階連續的特性，經過多年的研究和探討，直到b樣條函數的出現和發展，才給船體型線的計算機輔助設計，帶來了突破性的進展。
