摘要翻译：
用Monte-Carlo模拟研究了二维Ising模型中有序参量与晶格振动耦合时相图和图形的形成。结果表明，如果耦合足够强（或声子足够软），在较宽的温度区间内，无序相中存在短程有序。根据温度和模型参数的不同，研究了不同类型的这种短程顺序（条纹状、棋盘状等）。随着耦合度的进一步增加，在足够低的温度下，基态发生重构，并出现新的有序相。

英文摘要：
Phase diagram and pattern formation in two-dimensional Ising model with coupling between order parameter and lattice vibrations is investigated by Monte-Carlo simulations. It is shown that if the coupling is strong enough (or phonons are soft enough) a short-range order exists in disordered phase for a broader temperature interval. Different types of this short-range order (stripe-like, checkboard-like, etc.) depending on the temperature and model parameters are investigated. With further increase of the coupling, a reconstruction of the ground state happens and new ordered phases appear at low enough temperatures.
