| Abstract: | The line effect of ultrafine particle and the anharmomic effect of atom vibration are accounted for.The equation of the surface energy of ultrafine particle varing with the temperature and size is presented microlos mically.When it is applied to Ag ultrafine particle,the theoretical calcalations are identical to the resurts from measuring melting temperature and using theormodynamics methods. |
