摘要采用抛物型Frenkel-Kontorova模型研究了双晶体系统界面能的失配依赖性。得到了一个精确解，证实了其他作者从更复杂模型的近似解中得出的结论。主要结论是，在图中存在各种强度阶的点极小值，其中晶格常数是小整数的比例，并且先前不太精确的计算预测了平滑变化。得到了失配复杂度与最小值强度阶数之间的相关关系。
Abstract A parabolic Frenkel-Kontorova model was used to investigate the misfit dependence of the interfacial energy of a bicrystal system. An exact solution was obtained substantiating the conclusions drawn by other authors from approximate solutions of more complicated models. The main conclusion is that pointed minima of various orders of strength exist in the graph where the lattice constants are in the ratio of small integers and where previous less accurate calculations predicted a smooth variation. A correlation between the complexity of the misfit and the order of strength of the minima is also obtained.
