具有球面叶层结构的二次广义Hamilton系统模型广泛存在于许多化学、物理、力学问题中.对此类系统的平衡点个数、稳定性随参数变化的规律进行了较深入的研究,获得了Hamilton函数H=1/2U^2+1/2λu^2+Au+Bu+Cw中A=1时的全局相图.
A generalized Hamiltonian system with sphere leaves was studied, bifurcation and stability of equilibria were discussed in detail. The phase portraits with Hamilton function H=1/2U^2+1/2λu^2+Au+Bu+Cwwhen λ = 1 were obtained on sphere leaves.
