By properly setting the coordinateaxis, the discrete data of a symmetric coupler curve are made to satisfy the conjugate symmetry.
通过合理地选择坐标轴，使对称连杆曲线的离散数据满足共轭对称性。

Theoretically speaking, it is a rather-clearly discussed subject to standardize the quadratic equation into the normal forms by spinning the coordinateaxis so as to approach the shapes of its curves.
