摘要
文献[1]中创立了一种很有用的面积坐标,但是未弄清楚面积坐标系与原有的一些坐标系之间的联系,并且出现了"若u1+u2+u3=0,就说(u1:u2:u3)代表一个无穷远点"等错误,本文就这些问题进行解析,并得到结论:面积坐标系就是一种特殊的射影坐标系。
Literature[1] has created a very useful area coordinate,but not well understood the link between the area coordinate system and some of the original coordinate system.In addition,there appear some errors like"if the u1+u2+u3=0,that is(u1:u2:u3)represent a infinity points".This article wants to analyze these problems and gets conclusion,area coordinate system is a special kind of projective coordinate system.
