【Abstract】 The development and study of methods to prepare carbon foils and to determine their thicknesses are described. The methods of making carbon foils consist of carbon-arc evaporation, resistance heating, electron bombardment, cracking ethylene and centrifugal precipitation. Weighing, a-particle measurement, Rutherford backscattering and spe-ctrophotometer are used to determine the thickness of carbon foils.更多还原
