从扫描隧道显微镜研究的结果，我们表明，在Pt（100），（i）之间的边界不同的旋转域的六边形重建只发生在步骤和（ii）步骤的方向，也没有（iii）的取向的各个bridbored域决定的方向重建域。畴-畴和畴-台阶相互作用以相同的顺序减小;它们的大小和畴重新取向的激活能与该表面在1100 K时的结构转变有关。
From results of a scanning-tunneling-microscopy study we show that, on Pt (100),(i) boundaries between different rotational domains of the hexagonal reconstruction only occur at steps and (ii) neither the step direction nor (iii) the orientation of the respective neighbored domain dictates the direction of the reconstructed domain. The domain-domain and domain-step interactions decrease in the same order; their magnitude and the activation energy for reorientation of domains is related to a structural transition of this surface at 1100 K.
