Theconfigurations and interactions in a system of particles connected by liquid bridges are investigated. The basic phenomena have been elucidated using two-dimensional models with equal sized particles. With this restriction all possible contact configurations can be obtained by considering three particles. Different configurations of the liquid distribution can occur depending on the amount of liquid. For small quantities of interstitial liquid, the only possible configurations are pendular bridges. For large amounts of liquid a fully saturated state called the capillary state can exist. There are also a number of intermediate cases characterized by varying degrees of interstitial voidage, which are classified as funicular configurations. The interactions of the particles by means of the interstitial liquid binder in various possible configurations have been characterized, and the interparticle forces and the energy of the system due to the capillary action of the liquid bridges have been calculated. The changes in configuration, force, and energy as one particle is pulled away are also considered. Since the parametric space for calculation is large, only two representative cases are presented.

研究了由液桥连接的粒子系统中的构型和相互作用。利用具有等尺寸粒子的二维模型阐明了基本现象。在这种限制下，通过考虑三个粒子可以获得所有可能的接触构型。根据液体的量，可能会出现不同的液体分布构型。对于少量的间隙液体，唯一可能的构型是悬垂桥。对于大量液体，可能存在一种称为毛细管状态的完全饱和状态。还存在许多以不同程度的间隙空隙率为特征的中间情况，这些情况被归类为缆索构型。已经表征了在各种可能构型中粒子通过间隙液体粘合剂的相互作用，并计算了由于液桥的毛细作用而产生的粒子间力和系统能量。还考虑了一个粒子被拉开时构型、力和能量的变化。由于计算的参数空间很大，仅给出了两个代表性案例。版权所有1999年学术出版社。
