We use the Cellular Potts Model (CPM) to study the contact angle (CA) hysteresis in multiphase (solid-liquid-vapour) systems. We simulate a droplet over the tilted patterned surface, and a bubble placed under the surface immersed in liquid. The difference between bubbles and droplets was discussed through their CA hysteresis. Dependency of CA hysteresis on the surface structure and other parameters was also investigated. This analysis allows decoupling of the 1D (pinning of the triple line) and 2D (adhesion hysteresis in the contact area) effects and provides new insight into the nature of CA hysteresis.
我们使用元胞自动机模型（CPM）来研究多相（固-液-气）系统中的接触角滞后现象。我们模拟了一个在倾斜图案表面上的液滴和一个在浸没在液体中的表面下的气泡。通过它们的接触角滞后现象讨论了气泡和液滴之间的差异。还研究了接触角滞后现象对表面结构和其他参数的依赖性。这种分析可以分离出 1D（三线钉扎）和 2D（接触区域的粘附滞后）效应，并提供对接触角滞后现象本质的新见解。
