摘要翻译：
在随机场强度分别为$H_r$=1和2的情况下，我们对$L\乘L\乘L$简单立方晶格上的三维随机场XY模型进行了蒙特卡罗研究。我们给出了角平均磁结构因子的结果，$s(k)$在$l=64$。我们的结果似乎表明了向铁磁状态的相变。格里菲斯奇点的存在使这成为可能。似乎在相变时$m^2$不连续地跳到零，潜热可能是次广泛的。

英文摘要：
We have performed Monte Carlo studies of the 3D random field XY model on $L \times L \times L$ simple cubic lattices, with random field strengths of $h_r$ = 1 and 2. We present results for the angle-averaged magnetic structure factor, $S (k)$ at $L = 64$. Our results appear to indicate a phase transition into a ferromagnetic state. This is made possible by the existence of a Griffiths singularity. It appears that at the phase transition $M^2$ jumps to zero discontinuously, with a latent heat which is probably subextensive.
