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.
