| Abstract: | The method of qualitative analysis of differential equation and bifurcation is employed to study two classes of quartic systems. The parameter space is partitioned. The phase portraits are divided into three classes. The concrete phase portraits are given. Numerical simulation shows the correctness of the theory result. |
