| Abstract: | The single metal film has been gotten after the special experiment. During the diamond systhesis, the change of composition and matter transmission have been found from the echamical composition analysis on the matter film. Some theories explainning this phenomenon were introduced in this paper, and the nonequilibrium interval solid solution mechanism of diamond synthesis was proposed. |
