摘要
在自洽平均场的理论基础上，讨论了S=1Heisenberg反铁磁链Haldane能隙对外场的依赖特性.给出了能隙随外场变化的数值关系，并与电子自旋共振技术实验以及其它理论所得的结果进行了比较.
This paper discusses the field dependent properties of the spin-1 Heisenberg antiferromagnetic chain with the self-consistent mean-field theory. Numerical results of the Haldane gap as a function of external magnetic field concerned are presented and compared with experiment results via electron-spin-resonance technique and other theories.
