| Abstract: | Using 2-dimensional rotation transformations to cancel mixed terms of the product of two variables,and making use of translation transformations to simplify quadric surface equations,a new method for simplifying quadric surface equations has been obtained.It is easy to localize the position of quadric surface in the coordinate by using this method. |
