arc spline 解釋
弧形樣條線
  • arc : A. R. C. ＝ American Red Cross 美國紅十字會。n. 1. 弧；弓形，拱（洞）。2. 電弧，弧光。
  • spline : n. 1. 【機械工程】花鍵；方栓；止轉楔；齒槽，齒條，鍵槽條。2. 【建築】塞縫片。3. 活動曲線規。vt. 1. 開鍵槽于。2. 用花鍵（或方栓）聯接。
  1. They not only inherit the advantages of bezier curves and b - spline curves, also can be used to represent straight lines precisely and some remarkable transcendental curves precisely, such as circular arc, ellipse, cardioids and twisted pair line etc. especially, the uniform t - b - spline curve of three degrees is smoother than b - spline curve and c - b - spline curve of the same order

    此外由於它們還具有三角函數的優點，故既可以精確表示直線段、二次多項式曲線段又可以精確表示圓弧、橢圓弧等二次曲線以及心臟線、雙紐線等超越曲線。特別地， 3次均勻t - b樣條曲線曲面比同階均勻b樣條（ c - b樣條）曲線曲面具有更高的光滑度。
  2. Secondly, to counter contour curve for large sole of rubber overshoes, the way of linear circle arc spline of two dimensions curve fitting has been raised in this paper and autocad has meanwhile been applied in cad / cam integeration system of rubber overshoes mould, and also a whole set of software and hardware technique developed, and the selecting way for optimizing tool path worked out. this way may make nc machining free running minimun

    其次，針對膠鞋大底的輪廓曲線，對圓弧樣條進行了深入研究，提出了二維曲線擬合的線性化圓弧樣條方法；同時將autocad應用於膠鞋模具cad / cam一體化系統中，成功地開發了一整套相應的軟硬體應用技術，提出了刀具軌跡優化的動態選擇法，以便使nc加工的空行程相對極小化。
  3. Design of rectangle spline refined hob fitted by least squares twin arc

    最小二乘法雙圓弧擬合矩形花鍵精滾刀的設計
  4. 4. the author particularly discussed the drafting method of involute, using spline which is defined by many points to construct involute. compared with other involute defined by arc or straight line segment, the precision of this kind of involute is improved evidently

    4 .對齒輪漸開線的造型方法進行了詳細的分析研究，用多點定義的spline線來構造漸開線，與用圓弧或直線段擬合方法相比，漸開線的精度得到顯著提高。
  5. In the chapter four, extension algorithms for b - spline curves are investigated. the new step - iterative method of parameterization by accumulative arc length is proposed

    第四章研究b -樣條曲線的延伸演算法，提出了逐步累加弧長參數化方法。
  6. By adjusting the given tangent vector, the parametric rational arc spline also has convexity preserving property and monotonicity preserving property

    在實際操作中，通過調整一側端點的切向量，可使上述圓弧樣條曲線保凸，保單調。
  7. The on - line stroke recognition algorithm can recognize the rough strokes and transform them into three basic geometric line - elements, including straight line, arc and b - spline

    筆劃的在線識別主要是將原始筆劃轉換為規則的基本幾何線元，即直線條，圓弧，和樣條曲線。
