plane vector field
Examples
- Physical feature - dependent topological simplification and data compression of planar vector fields
与物理特征相关的平面向量场的拓扑简化及压缩 - In the fourth part , by using the bifurcation theory of planar dynamical systems and the method of detection functions , the paper gives a configuration of limit cycles forming compound eyes . with the help of numerical analysis ( usi ng maple ) , it is shown that there exist parameter groups such that a z7 - equivariant planar polynomial vector field of degree 7 has at least 36 limit cycles with z7 - symmetry
然后，对于一组特定的参数值，研究了它的相轨线的变化趋势；第四部分指出：在一定的条件下，利用平面动力系统分支理论以及判定函数法，在计算机数学软件( maple )的帮助下，得到结论： 7次z _ 7 -等变平面向量场至少有36个极限环，形成具有z _ 7 ?对称性的极限环分布。 - By using the bifurcation theory of planar dynamical systems and the method of detection functions , this paper gives a configuration of limit cycles forming compound eyes . with the help of numerical analysis ( using maple ) , it is shown that there exist parameter groups such that a polynomial vector field of degree 7 has at least 49 limit cycles with z8 - symmetry
然后，利用平面动力系统的分支理论以及判定函数法，考虑z _ 8 -等变的扰动hamilton向量场，在计算机数学软件( maple )的帮助下，我们得到结论： 8次平面向量场至少有49个极限环，形成具有z _ 8 -对称性的极限环分布。
