By properly setting the coordinate axis, 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。
In this paper, we study the symmetry on distribution matrix of order statistic of discrete type random variable. Therefore, we obtain two theorems.
