| Abstract: | From mechanics and energetics point of view, this paper proves concisely that the pressure difference between inside and outside of a crown-shaped droplet on the surface of a condenser is different from that of a spherical droplet in the condenser, and indicates its disagreement with that shown in the paper by Min J C, 2002, Acta Phys. Sin. 51 2730. The reason is given in this paper. |
