摘要
用微用方程定性分析方法和分支方法研究一类四次系统,参数空间被划分,系统的相图被分成 8类,具体相图被给出,数值模拟进一步验证了理论结果的正确性.
The method of qualitative analysis of differential equation and bifurcation is employed to study a class of quartic system.The parameter space is partitioned.The phase portraits are divided into eight classes.The concrete phase portraits are given.Numerical simulation shows the correctness of the theory result.
