我们构造了平面伊辛铁磁体在亚临界温度下的路径求和表示。这些路径是体相关长度尺度上的Gibbs分割面，并由表面张力和表面刚度等粗粒化量控制。我们以受控的方式重新捕获了关联函数的唯象泡泡模型，并且我们能够考虑体积场的标度极限和影响。
We construct path-summation representations for the planar Ising ferromagnet at subcritical temperatures. The paths are Gibbs dividing surfaces on the scale of the bulk correlation length, and are controlled by coarse-grained quantities such as the surface tension and the surface stiffness. We recapture the phenomenological bubble model of correlation functions in a controlled way, and we are able to consider the scaling limit and the influence of a bulk field.
