将密度矩阵重整化群方法推广到一维随机系统。用这种方法计算了自旋为1/2的无规反铁磁海森堡链的能隙分布。结果与重正规化群理论的预测一致，证明了本方法在随机系统中的有效性。讨论了本方法在其它随机系统中的可能应用。
The density matrix renormalization group method is generalized to one-dimensional random systems. Using this method, the energy gap distribution of the spin-1/2 random antiferromagnetic Heisenberg chain is calculated. The results are consistent with the predictions of the re- normalization group theory demonstrating the effectiveness of the present method in random systems. The possible application of the present method to other random systems is discussed.
