摘要
利用坐标变换给出了一种求旋转曲面方程的方法,并举例说明用该方法可以直接从方程判断出它所表示的曲面类型.
Firstly, by using coordinate transformation, a method obtained the equation for surface of revolution is proposed. And then some examples are provided to illustrate that the types of the surface of revolution can be judged directly from the equations by using our method.
