摘　　要：极坐标系的分析方法在解决许多几何问题时有很好的效果,以计算平面图形的面积为例,讨论了极坐标系中如何在没有图形的情况下分析其几何性质。We all know that analytical methods in polar coordinate are widely applied in resolving geometry problems. In this paper, the methods on how to analysis the property of geometry curve when we need not draw the graph were discussed in polar coordinate, for this, the examples of calcu- lating the area in polar coordinate were quoted.

关 键 词：极坐标 无图形处理 几何性质 面积 分布范围 对称性 封闭性
