Curves and surfaces are the main research content of space analytic geometry, the relevant theoretical knowledge is widely applied, so for our graduates with good research value. Plane of rotation is a kind of special curved surface, it is widely used, I also we study some elliptic surface based. This thesis mainly discusses the rotating curved surface equation and parametric equation and drawing method. Based on the rotating surface characteristics of the formation, by means of coordinate transform knowledge analysis discussed the space curve rotation around the axis formed by the rotating curved surface equation and parametric equation, and introduces the parameter equation based on the application of Mathematica painted related rotating curved surface method. In addition, based on the coordinate transformation theory, we studied spatial curve space straight line rotating around a rotating surface parameter equation. Related to the content on mathematics undergraduates have a good reference value.
