【摘要】Usually the Virial thcorem,which can be derived from the Feynman-Hellmann

theorem,applies

to

Hamil-tonians

without

coordinates-momentum coupling.In this paper we discuss when there are such kind of couplings in Hamiltonians then how the Virial theorem should be modified.We also discuss the energy contribution arising from the coordinates-momentum coupling for a definite energy level. 【总页数】3页(117-119) 【关键词】
