【Abstract】 The calculation and calibration problems we meeted while using isotopic instruments to measure the thickness are probed into in application theoretically and practically. By using the relative measuring and the calculating method are discussed, the influence of interfering factors on the measurement result is effectively eliminated. As a result, the measuring precision is improved from 4.9% to 3.8%.更多还原
