解釋
空間多邊形-
This paper also analyzed some key problems in 3d triangulation from scattered points. new determining principles for the relationship of point and line in space and for convexo - concave vertices of space polygon is discussed which corrected the previous method and can be applied in space triangle mesh. at the end of this papar, the future research areaes of triangluation from 3d scattered points are demonstrated
本文還分析了三維空間直接三角剖分所要解決的一些關鍵問題，進而提出了空間中點與直線位置關系判別的新方法及空間多邊形頂點凹凸性判別的新方法，修正了以往演算法在應用上的局限性，使之能夠適用於復雜網格多邊形邊界。 -
The chemical components of silkworm pupa crust were analyzed, and its microstructure was characterized by using scanning electron microscope. the existing realtion of among chitin 、 protein and inorganic salt in silkworm pupa crust has been observed. the results show that the major protion of silkworm pupa chitin is in pupa crust, and it accounts for about one forth of crust weight, the out surface of pupa crust is regular polygon net vein characteristics. chitin takes honeycomb shape in chitin - protein complex and conjugated with protein. the inner space of chitin - protein complex net was filled with inorganic salts. thus the theory basis was provided for working out the process route of isolation pupa chitin
對桑蠶蛹皮的成分、結構進行了化學及掃描電鏡分析，確定其含有的主要成分及含甲殼素的數量，並對其中的甲殼素、蛋白質和無機鹽三者之間的存在方式進行了觀察.研究結果表明，蛹體中的甲殼素與灰分主要含在蛹皮中，甲殼素占整個蛹體成分的2 . 71 % ，占蛹皮重量的25 . 5 % ，蛹皮外表面呈規整的多邊形網狀結構，蛹皮中蛋白質與蜂窩狀的甲殼素相結合，呈層狀分佈，顆粒狀的無機鹽填充在甲殼素/蛋白質復合物構成的蜂窩狀的空隙中.這為制定提取蛹甲殼素的工藝路線提供了理論依據 -
The surface detail or offsets simulated by a normal map are always relative to either the polygon it ' s projected on ( tangent space ) or the object ' s orientation ( object space ) or the world ( world space )
（通過法線貼圖計算出的表面細節和偏移是總是相對于多邊形的投影方向或是物體的自身軸向（物體空間）或是世界（世界空間）的。 ） -
Firstly, singly linked lists are used as the data structure of this algorithm rather than doubly linked lists or trees as other algorithms use, so less memory space and running time are required. secondly, the relationship between the entry and exit points on the two polygons is found and argumentation, which, with the reasonable operations on the lists, reduces the times that the lists are traversed and allows the polygon to be input clockwise or counterclockwise
該演算法使用單線性鏈表數據結構，與其它使用雙鏈表或樹結構的演算法相比具有佔用空間少及處理速度快的特點；其次，找出並論證兩個多邊形之間進、出點之間的關系，並通過合理的數據結構處理，減少了演算法對多邊形鏈表的遍歷次數，而且允許多邊形既可以按順時針方向也可以按逆時針方向輸入。
