简介：一个简单立方的格子的脱臼方程被与微分术语和不可分的术语预先明确地被给了的秒顺序的系数基于分离格子理论使用格林的功能方法获得了。我们讨论了的简单立方的格子是一个可解决的模型，它根据格子静电干扰和对称原则被获得并且能验证并且验证脱臼格子理论。它能介绍对大多数有仲裁格子结构的金属合适的统一脱臼方程。通过把现在的可解决的模型的结果与脱臼格子理论作比较，这能被看见，然而，我们获得的边和螺丝钉部件的不可分的术语的系数根据脱臼格子理论的结果螺丝钉部件的微分术语不与脱臼格子理论的结果一致的秒顺序的系数。这被表面术语的减少的动态矩阵主要引起，它是本质获得脱臼方程。根据简单立方的可解决的模型，不是仅仅直脱臼而且弄弯的脱臼的意见，例如纽结，能进一步被调查。
