In this article, we review both theoretical models and experimental results on the motion of micro- and nano- particles that are close to a fluid interface or move in between two fluids. Viscous drags together with dissipations due to fluctuations of the fluid interface and its physicochemical properties affect strongly the translational and rotational drags of colloidal particles, which are subjected to Brownian motion in thermal equilibrium. Even if many theoretical and experimental investigations have been carried out, additional scientific efforts in hydrodynamics, statistical physics, wetting and colloid science are still needed to explain unexpected experimental results and to measure particle motion in time and space scales, which are not accessible so far.
在本文中，我们回顾了关于接近流体界面或在两种流体之间运动的微纳米颗粒的运动的理论模型和实验结果。粘性阻力以及由于流体界面的波动及其物理化学性质引起的耗散强烈影响胶体粒子的平移和旋转阻力，胶体粒子在热平衡中受到布朗运动的影响。即使已经进行了许多理论和实验研究，但在流体动力学、统计物理、润湿和胶体科学方面仍需要进一步的科学努力，以解释意外的实验结果，并测量迄今为止无法达到的时间和空间尺度上的颗粒运动。
