我们考虑液滴沉积在纹理粗糙表面上的微观接触状态。比较了三种可能的（元）稳定润湿状态的能量，并将能量最低的状态视为“相”。我们在织构参数的二维空间中给出了“相图”，这表明了在润湿状态之间的转变。我们提出了一个模型，该模型允许描述（元）稳定接触状态之间的过渡状态，并量化它们之间的能量势垒。因此，我们从理论上提出，实际实现的状态并不总是最低能态。
We consider microscopic contact states of a drop deposited on textured rough surfaces. The energies of three possible ( meta) stable wetting states are compared and the lowest energy state is regarded as the " phase". We present the " phase diagrams" in the two-dimensional space of texture parameters, which suggests transitions between the wetting states. We propose a model which allows the description of transition states between ( meta) stable contact states and quantify the energy barriers between them. Thereby, we theoretically suggest that the actually realized state is not always the lowest energy state.
