  1. The paper has improved the existing lifting - line and lifting - surface design method by including the rake and skew and solving the optimum circulation distribution with the optimum theory. the blade geometry is expressed with b - spline for the lift - surface method. the boundary condition on the blade is transformed to minimize the summation of the square of normal velocities, the fair blade geometry can be obtained by present technique and the design quality is better

    改進了現有的升力線和升力面設計方法，在升力線設計中計及槳葉的縱傾和側斜的影響，用優化理論求解最佳環量分佈，升力面設計中用b樣條來擬合槳葉，將物面邊界條件轉化為求法向速度分量的平方最小，由此可得到光順的槳葉幾何形狀，提高和改進了設計質量。
  2. The commissioning of the shenzhen bay and lok ma chau spur line boundary - crossing points in 2007 will help alleviate congestion at existing boundary - crossing points

    為紓緩現時各邊境管制站的擠迫情況，深圳灣管制站及落馬洲支線管制站，將於二零零七年啟用。
  3. Moreover, based on in - depth research of " the existing scan - line polygon fill algorithm, the author has introduced a new fast method for clipping arbitrary boundary areas algorithm which uses the edge consistency and the scan - line consistency and adopts sorted chain table, i t can reduce the quantity of calculating intersection points and improve the efficiency of algorithm

    另外，作者在對已有的掃描線填充演算法深入研究的基礎上，介紹一種利用裁剪區域的邊的連貫性和掃描線的連貫性，從而減少求交計算量、提高演算法效率的有序鏈表的快速裁剪演算法。
