摘要
考虑了一类7次一等面Hamikon向量场，通过定性分析和数值计算获得如下结果：具有最多奇点个数时此向量场的相图至少有9种：
A Z2-equivariant planar Hamilton vector field of degree 7 is consid-ered ,By using the qualitative and numerical computation,the following results can beobtained：1） The vector field having maximal centers has at least 9 different phase por-traits; 2） One of the phase portraits＂ orbit analysis is given.
