给出了量子场模型（包括无质量模型）中基态简并度的上界。特别地，给出了扰动哈密顿量的基态简并度小于或等于未扰动哈密顿量的基态简并度的一个充分条件.概述了抽象理论在量子场论模型中的应用。
Axiomatic abstract formulations are presented to derive upper bounds on the degeneracy of the ground state in quantum field models including massless ones. In particular, given is a sufficient condition under which the degeneracy of the ground state of the perturbed Hamiltonian is less than or equal to the degeneracy of the ground state of the unperturbed one. Applications of the abstract theory to models in quantum field theory are outlined.
