中文摘要
      利用一种判别系统稳定性的定号导函数方法——正则判别函数法，结合Normal Form 理论，对二维三次非线性系统的两种临界情形进行了稳定性分析，即对含一对纯虚根和含几何重数为一的两个零根的纯临界系统，分别给出了一组系统稳定的充分条件，并给出了相应的李亚普诺夫函数的形式.
英文摘要
      This paper analyses the stability of two-dimensional three-degree critical nonlinear tsyzstenrs. by using the Normal Determinative Function Method，which is a definite derivative function method to judge Lyapunov stability of systems. Two cases are considered，where the pure critical system has a pair of nonzero pure imaginary eigenvalues and two zero eigenvalues with geometric multiplicity one. For each system，the sufficient conditions for stability and the form of Lyapunov function are given.
