利用MacKinnon有限尺寸标度法对二维随机磁场中波函数的局部化问题进行了数值研究。证实了单参数标度关系，得到的标度函数β(g) （g为无量纲电导）在g -4以内与最近的解析结果一致，表明所有波函数都是局域化的
The localization of the wave functions in a random magnetic field in 2D is investigated numerically in terms of MacKinnon's finite size scaling method. The single-parameter scaling relation is confirmed, and the scaling function β(g) (g is the dimensionless conductance) obtained for this unitary model is consistent with the recent analytical result up to g -4 , indicating that all the wave functions are localized
