标题： Comment on: Dynamic and Static Properties of the Randomly Pinned Flux Array

摘要： 我们重新考虑了随机钉扎平面通量阵列（或无涡旋的二维XY模型）在广泛蒙特卡洛模拟中的模型。 我们表明，与最近的报道[Phys. Rev. Lett.{\bf 72}, 4133 (1994)]相反，对于较大的无序值，无序平均位移关联函数与纯情况不同。 其作为无序对数函数的斜率与新的RG计算结果一致。 显示英文摘要

摘要： We reconsider the model of the randomly pinned planar flux array (or the two-dimensional XY-model with random fields and no vortices) in extensive Monte Carlo simulations. We show that contrary to what has been reported recently [Phys.\ Rev.\ Lett.\ {\bf 72}, 4133 (1994)] the disorder-averaged displacement correlation function is different from the pure case for larger values of the disorder. Its slope as a function of the logarithm of disorder is compatible with newer RG-calculation results.
