摘要：

We consider the equilibrium position of a solid spherical particle at a curved liquid/liquid interface. Our analysis is based on the total free energy of the system. It is shown in particular that (i) the contact angle at the three-phase line obeys the Young equation, and (ii) the particle is never ejected out of the droplet, whatever the curvature of the interface. We then study the equilibrium position of a "Janus bead," that is, a spherical particle with hemispheres of different surface energy. © 1990.
