摘要翻译：
利用Monte Carlo模拟和有限尺度缩放技术研究了模型胶体在一维外周期势存在下的二维熔化转变。本文研究了一个可公度比$p=\sqrt{3}a_s/(2d)=2$的硬盘系统，其中$a_s$是磁盘间的平均距离，$d$是外部电位的周期。观察到了三个相，即调制液体、锁定近晶和锁定浮动固体，与其他实验和分析研究一致。利用序参量、累积量和响应函数等统计量，得到了这三个相之间的相图。

英文摘要：
  Two-dimensional melting transitions for model colloids in presence of a one-dimensional external periodic potential are investigated using Monte Carlo simulation and Finite Size Scaling techniques. Here we explore a hard disk system with commensurability ratio $p=\sqrt{3}a_s/(2d)=2$, where $a_s$ is the mean distance between the disks and $d$ the period of the external potential. Three phases, the modulate liquid, the locked smectic and the locked floating solid are observed, in agreement with other experimental and analytical studies. Various statistical quantities like order parameters, their cumulants and response functions, are used to obtain a phase diagram for the transitions between these three phases.
