缺参数a_(23),b_(32)的齐五次系统的前四阶鞍点量公式

Calculation Formula of the First Four-Order in AbsentParameter a_(23),b_(23) System of Degree 5

将系统经变换化为广义齐三次系统,根据广义齐三次系统的鞍点量计算方法,给出(缺参数a23,b32)齐五次系统的一、二、三、四阶细鞍点量的参数表达式.为进一步讨论齐五次系统鞍点量上界问题作准备.

Homogeneous system is transformed into a generalized cubic homogeneous system. The system offers parameter expression of the first, second, third and fourth order weak saddle values of degree 5 （ absent parameter a23, b32 ） by calculating formula of saddle values of the generalized cubic homogeneous system. To discuss the upper bound problem of saddle values of the degree 5 system.
