退化二次曲线的逆曲线

Inverse Curve of a Degenerated Quadric Curve

对于退化的二次曲线Γ,利用其系数矩阵A的伴随矩阵A*定义了Γ的逆曲线,并根据原退化二次曲线的类型和图形对其逆曲线的图形进行了讨论.

Using the coefficient matrix A＊ of a degenerated quadric curve Γ ＇s adoint matrix A,a definition to the inverse curve Γ＊ of Γ was given,the graph of an inverse curve of Γ acoording to the type and specific figure of Γ were discussed.
