摘要
本文主要讨论了Ｈｅｌｌｍａｎｎ—Ｆｅｙｎｍａｎ定理在求解量子体系力学量平均值和体系能级等问题中的优越性，并就将其应用到定态做扰理论的情形进行探讨；提出了在类氢离子体系中所遇到的困难．
The advantage of Hellmann-Feynman theorem in solveing both the average of mechanical quantity of quantmn system and system energy level is discussed Its application to stationary state perturbation theory is studyed.The difficulties it meets in hydrogen-like ion are presented.
