The cell cycle and apoptosis and the expression of P-pg, bcl-2, P53 in the MG63 and MG63/R cell lines were analyzed by flow cytometry. Results The resistance index of the MG63/R cells to cisplatin was 83.557±4.841. The cells also had resistance to doxorubicin, vincristin, methotrexate and cyclophosphamide. Disordered structure of the MG63/R cells was observed through microscopy. The cells appeared in triangle, polygon and polynucleation. The increase of granular endoplasmic reticulums and apophyses was observed through transmission electron microscopy. The proliferation ability of MG63/R increased significantly, with a low apoptosis index.

结果 经顺铂186d的诱导，建立了MG63/R，其对顺铂的耐药指数为83.557±4.841，对阿霉素、长春新碱、氨甲基蝶吟、环磷酰氨亦产生不同程度的交叉耐药；光镜观察可见MG63/R细胞排列不规则，形态呈三角形、多角形及多核现象；透射电镜显示MG63/R细胞表面突起增加，粗面内质网丰富；细胞周期分析显示细胞增殖能力明显增加而细胞凋亡明显降低；MG63/R细胞 P-pg、bcl-2阳性表达较MG63细胞明显增加，P53表达则明显降低。

When t=1/2, Path of the C-curves and H-curves ofdegree two and three are lines, but not for the Path of degree four, weneed more about the control polygon. Paths are commonly curves. Butthe reference [38] pointed out that they can closely be approximated bylines. By this method we can get a C-curve passing a given point easily.

一般情况下，C曲线族的Path也是曲线，文献[38]以三次C曲线为例，提出用直线进行近似，应用这一方法，我们可以简洁的求出过一定点的C曲线，只要给定的点在C曲线族的范围内，则可以首先求出过这一点的C曲线族的Path，然后可以确定过这一点的C曲线的形状参数α，以及曲线参数t.H曲线的情况与C曲线类似。

A testing triangulation experiment for a polygon with 100 inside islets was done with this algorithm, and the result showed that this algorithm is efficient and robust for triangulating complex polygons with large numbers of inside islets. This algorithm has been successfully applied to the three- dimensional ore-body modeling and visualization system, in which it is used to triangulate the sectional polygons with inside islets, e.g., the inside stones or holes in ore-body, and its high efficiency has been proved.

实验表明，该算法在含有大量岛屿的带岛屿多边形三角剖分中具有很高的时间效率和很强的鲁棒性，并成功将其应用到基于剖面的三维矿体建模与可视化系统中，解决了含有夹石或孔洞的矿体剖面多边形三角剖分问题，具有一定的实际应用价值。

The term polygon is synonymous with area in vector databases because of the use of straight-line connection between points.

在矢量数据库中多边形与区域是同义词，因为都是以直线相连的点。

Billion-dollar titans such as DB Zwirn and Polygon threw in the towel. Five of the best-paid managers endured a pantomime grilling by Congress .
