【Abstract】 In measuring the ratio of fluctuation of speed the paper proposes usingmicrocomputer instesd traditional measuring devices. We prensent the data aquisitionsystem and data management methods, propose to determine the maximal speed andminimal speed. The microcomputer system exactly and rapidly shows the ratio of fluctuation of speed.更多还原
