三次曲线牛顿分类法的研究

The Coordinate Systems for Standard Equations of Cubic Curves Newton's Classification

应用三次曲线的配极理论及其基本性质 ,讨论了三次曲线牛顿分类的依据 ,确定了牛顿分类中 4种形式和 7类曲线所对应的坐标系。

Using the theories of polarity and the properties of cubic curves on Newton's classification. The relationships of the standard equations with the coordinate system, and also, every kind of cubic curves' standard equations were developted.
