摘　　要：运用经典哈密顿代数方法 ,结合陪集表象构造了类比于热力学中熵的H函数。研究表明 ,H函数随时间增加而增大的特性可以用来表示分子内振动能量传递的方向和限度。同时 。An H-function in analogy with the entropy in thermodynamics is proposed for intra-molecular vibrational energy redistribution (IVR) in an algebraic approach, which is based on an algebraic classical Hamiltonian on the coset sphere where actions are treated as continuous variables The time rate of the H-function serves nicely as a tool for IVR and is applied to show the resonances in H 2O and DCN in a compact way
