We discuss qualitative and quantitative aspects of the effective interactions between micrometer-sized colloids of different types trapped at fluid interfaces, with a particular emphasis on the relation between experimental and theoretical results. For colloids of that size, the interactions can broadly be classified into "direct" ones such as electrostatic, magnetic, or elastic ones. Such interactions appear also for colloids in bulk systems, but they are modified at interfaces. On the other hand, the presence of a fluid interface generates in addition interface-mediated (capillary) interactions which are either induced by nonspherical colloid shapes or by the "direct" interactions.
我们讨论了捕获在流体界面的不同类型微米级胶体之间有效相互作用的定性和定量方面，特别强调了实验结果与理论结果之间的关系。对于这种尺寸的胶体，相互作用大致可分为“直接”相互作用，如静电、磁性或弹性相互作用。这种相互作用在本体系统中的胶体中也会出现，但在界面处会发生改变。另一方面，流体界面的存在还会产生界面介导的（毛细）相互作用，这些相互作用要么由非球形胶体形状引起，要么由“直接”相互作用引起。
