| Abstract: | Under consideratidn of the effects of the first and second near neighbour atoms, three-dimension vibration modes of impurity atoms on crystal surface are fond by aid of computer, using the non-symmetrical pattern of three dimensions. With the partial mode, this paper explains qualitatively the different effects of the impurity atoms on the surface from in tile body on crystal heat properties |
