摘　　要：用Ｌａｎｃｚｏｓ方法计算出一维ＡＴ量子链的基态和低激发态的能量，求出了模型的反常标度和归一化常数。The energies of the ground state and the lowest excited states of the 1D AT quantum chain are calculated by using Lanczos method. The anomalous dimensions and normalized constant are given from conformal field theory.

关 键 词：共形场论 临界现象 量子链 A-T量子链
