摘要：
The thermophoretic force and ion-drag acting on micro-particles falling through a long RF plasma has been measured here under two different experimental situations: either an unperturbed plasma characterized by its symmetric potential and temperature distribution or a plasma with an asymmetric temperature and potential profile. The dominant effect of the gravitation force is reduced here due to the dynamic equilibrium with the friction force of the particles with the neutral gas.
