A fast algorithm for simple polygon triangulation is presented. Its thought is based on the dynamic judgment of interior angle. If the angle of point is smaller than 180 degree and includes no other points, then the point is connected into triangle. The data structure that enhances the efficiency of the algorithm is designed.

提出了一种内角动态判定的简单多边形三角剖分算法，该算法的思想是对多边形相邻三角点构成的内角进行动态判断，如果小于180度且组成的三角形是否包含其它点，则连成三角形，并设计了有利于算法快速实现的数据结构。

Results一. Culturing and identification of human conjunctiva cells1. morphous of conjunctiva cellsCells were harvested by tissue cultivation after digestion. Ponderosus cells adhered after 48 hours. Cells were shown in shape of round, ellipse and polygon. Cell body was loose and lucency with nucleus in center, cell membrane was also clearly seen. Cells were arranged in inlay and fuse in film after 12-14 days.2. Immunochemistry testNomogeneous immunochernical positive granules against CK13 were observed in endochylema of human conjunctiva cells.3. growth curve of conjunctival cellsSubcultured cells were aged and feeble after 5th passage.

Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.

本研究观察了从鸡胚到出壳后的不同生长发育阶段法氏囊的组织结构，结果表明：胚胎13日龄时，法氏囊开始发育，粘膜上皮下形成结节状细胞集团；胚胎15日龄，聚集的细胞集团形成初始的淋巴滤泡；胚胎18日龄到出壳后1日龄，滤泡内淋巴细胞数量增多，多数滤泡髓质和皮质界限仍不明显；7日龄雏鸡法氏囊髓质皮质分界清晰，滤泡数量显著增多；21日龄到35日龄，滤泡由多边形逐渐转变成长方形；在35日龄时，粘膜上皮细胞逐渐增多，排列紧密，细胞核紧密排列成直线位于基底部。
