▎ 摘　　要

NOVELTY - The method involves arranging a compound single layer graphene film on a graphene metal surface. A sample table is connected with an electric conduction atom force microscope. The graphene metal surface is fixed with a probe and electric conduction circuit. Determination is made to check whether a measured electric current value in lesser than a preset maximum current value. Minimum spectrograph wavelength value measuring process is performed. Voltage information recording process is performed. Graphene metal surface luminous spot information obtaining process is performed. USE - Graphene metal surface gap measuring method. ADVANTAGE - The method enables realizing metal surface gap measuring process in a simple and efficient manner. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a graphene metal surface gap measuring method. '(Drawing includes non-English language text)'
