摘　　要：本文讨论了在简谐振子形式下计算少体系统束缚态时利用对称性和低能态基矢对变分基的选取和简化,从而得到较简单的哈密顿矩阵,并利用此简化的基矢具体计算了3—α、4—α体系能谱。tIn calculating the bound states of few-body systems, in order to obeain a simple simple Hamiltonian matrix we here present a new method to choose and simplify the variational basis vetcors by means of the symmetry and the lower-energy states of the systems Using this method we have calculated, as examples, the energy levels of the 3- a and 4-a systems.
