  3. In conclusion, the design of automobile model is not only to reduce drag coefficient but also to improve lift coefficient, so the automobile has good performance

    綜合以上工作，明確了汽車車頭設計不僅要考慮空氣阻力系數的降低，同時要考慮升力系數的變化，以保證良好的行駛性能。
  4. The output axis and the piston have chosen high quality bearing which have good stability and sealing, low friction coefficient, large range of applicable temperature and long service lift

    輸出軸，活塞選擇了高質量的軸承，穩定性好，密封性好，摩擦系數低，適用溫度范圍大，使用壽命長。
  5. The paper researches the transient time precision and the following problem of the results developing with time for 2 - d high order blocking and matched method, at the same time, anlysing the stability of high order methods including boundary conditions. the results show that the domain decomposition and matched method using high order method can follow the time developing solution of taylor problem well, the computation result of the flow over a single or two tandem arranging circular cylinder agree the experiment and others " results well, moreover, the panting results of lift and drag coefficient are better than others

    本文利用高精度分塊耦合求解方法，對其瞬態時間精度和非定常時間發展解的跟隨性問題進行了研究，同時也對包含邊界條件的線法高精度格式的穩定性也作了分析，研究結果表明高精度的分塊耦合求解方法可以很好地跟隨taylor問題的時間發展解，與單圓柱繞流和雙圓柱繞流的實驗結果比較以及他人結果比較符合很好，對升阻力系數在渦脫落時的脈動問題的結果優於他人結果。
