摘要：

We have used computer simulations to study the effects of local distortions with given low symmetries on the structure factors and pair distribution functions of a two-dimensional binary crystal. The disorder leads to specific modulations of the diffuse scattering. In the case of clusters of such defects the diffuse scattering is distributed around the Bragg peaks. The length scales are found to be most directly identified by analysis of direct-space pair distribution functions.
