摘　　要：将一般n次中心—细焦点系统,转化为广义中心—细鞍点系统。为了进一步讨论全三次系统的细鞍点量上界问题,给出了该系统第8阶细鞍点全积分公式。在公式中,令θ=2πi就得到相应的细鞍点量公式。The center-weak focus of a general system of degree ＂n＂ was transformed into a problem of generalized center-weak saddle.The eighth complete integral of weak saddle was offered, for the purpose of further discussion about the upper of weak saddle of a cubic system. If θ is 2πi in the formulas, corresponding formulas of weak saddle can be obtained.

关 键 词：中心 焦点 鞍点
