  1. Quickly the trickle becomes a flood of glistening linseed oil as the beam sinks earthwards, taut and protesting, its creaks blending with the squeaking and rumbling of the grinding wheels and the occasional grunts and sighs of the camels

    譯文：隨著大樑越壓越低，纜索越繃越緊，大樑的嘎吱聲，石磙的轆轆聲，以及駱駝不時發出的咕嚕咕嚕的呼吸聲和嘆息聲響成一片，榨出的油也很快地由涓滴細流變成了一股晶瑩發亮、奔騰不止的洪流。
  2. The effective optimization design programs for different cases are developed by integrating the following several aspects which involves the flow analysis, adjoint equation solution, gradient solution, optimal arithmetic and grid generation. some practical design tests for airfoil and wing show that the continuous adjoint approach is very effective and useful method for aerodynamic optimization design. at the same time, we have done the research of aerodynamic optimum design for airfoils by using navier - stokes equations

    （ 4 ）研究了基於控制理論和三維navier一stokes方程的優化設計理論，在計算坐標下詳細推導了該優化設計理論，得到了計算坐標系下描述的共扼方程數學描述形式，並以給定目標壓力分佈的氣動反設計為例，導出了相應的共扼方程邊界條件，以及關鍵的梯度求解具體表達形式，為了求解方便，把計算空間上描述共扼方程表達形式變換到物理空間中進行描述，通過與ns方程表達形式對比分析，最終給出了一種直觀的共轆方程表達方式。
  3. In the computation procedure of the above problems, efficient algorithms to perform sparse matrix were applied to saving computer memory units and cpu time. the conjugate gradient method and biconjugate gradient method were applied to solve the sparse systems of generated linear equations

    為了減少計算機內存的需求和有效提高計算速度，本文在分析計算各類目標的電磁散射和輻射問題時，採用稀疏矩陣的存儲和壓縮技術，並運用共扼梯度和雙共轆梯度等方法求解線性方程組。
