摘　　要：定义了两种新矩阵运算,采用该矩阵运算方法,将中心-焦点型全6次系统改写成矩阵形式,并经可逆实对称变换将该系统化简.这种方法还可以应用到一般中心-焦点型n次系统中,它将简化计算焦点量上界问题.This paper defined two kinds of new matrix operation and applied the matrix operation method to rewrite center- focus entire setic systems into the form of matrix. It can reduce the system by real reversible symmetry transformation, and also such a method can be applied to analyze general center - focus type of n the order systems, so that simplify the calculation of upper boundary of the focus value.
