Thirdly, from the idea of locally linear approximate, another tangent - plane algorithm is presented for the distance between the convex nurbs surfaces. the critical step is the construction of the support mapping by gjk and lc to search for nearest points, and emphases are laid on dealing with isotropic cases and choosing initial iterated points. it is also proved that no isotropism during iteration would take place if initial iterated points are positive points
切平面法是運用gjk和lc構造支撐映射的原理而設計的一個搜索近點對的迭代法，著重給出了迷向情況的處理和初始迭代點的選取方法，並證明了只要將初始迭代點取為陽點，就不會出現迷向情況。 -
Miss distance parameters are estimated by matching pursuit algorithm to search the basis function which best matches the echo signal
通過匹配追蹤演算法尋找與回波信號最匹配的基函數來確定脫靶量參數。 -
In the course of the evolution of algorithm, the number of niche peaks is decided by seed identification and preservation process, the fitness ascending direction is applied to control search direction, adaptive population distance is used to control search range
演算法的進化過程中，通過物種的辨識和保存過程確定小生境的峰值，引入個體趨向于高適應度的方向這一控制參數控制搜索的方向，採用自適應調整種群距離的方法控制搜索的范圍，大大提高了搜索效率。 -
The calculation formula of micropiv technique is the original definition of velocity : v = [ s ( t2 ) - s ( tl ) ] / ( t2 - tl ). on the two neighboring frame of images, we search for the two small areas which have the largest correlation. by dividing their distance by their shooting interval, we got the average velocity of this small area in this interval, and then got the velocity of full flow
Piv測試原理的計算公式，是速度的原始定義： v = [ s （ t _ 2 ） - s （ t _ 1 ） ] （ t _ 2 - t _ 1 ） 。在相鄰兩幀圖像上，找出相關度最大的兩個小區域，用它們之間的距離除以兩次拍攝之間的時間間隔，就得到這個小區域在間隔時間內的平均速度，進而得到整個流場的速度分佈。
