摘要
本文根据曲线等距线方程式,用反证法证明了椭圆的等距线不是椭圆,用数值计算法验证了这一结论,进而推论出“已知曲线和它的等距线不都是同名曲线。”
According to the equation of curve's equidistant line,this paper proved that the equidistant line of a ellipse is not a ellipse,the conclusion is verified with numerical calculation method.Proceed to the next step,a deduction is made:“not all curves and their equidistant lines are same mame curves”.
