摘　　要：用重整化群方法研究一类两个自由度Hamilton系统,得到了这类Hamilton系统的O(ε)阶重整化群方程,并证明该重整化群方程也是Hamilton系统.Using the renormalization group method,we investigated a class of Hamiltonian systems with two degrees of freedom,and obtained the renormalization group equation to O(ε)order of this kind of Hamiltonian systems.Meanwhile,we proved that the renormalization group equation was also a Hamiltonian system.
