摘要
Abstract
A new model w hich describes the attenuation of X-ray in the X-ray thickness gauge was proposed .Based on measured data of several calibration plates whose thick-ness is already known ,this model was compared with other gauging models mentioned in other papers according to different numbers of data points ,different data point distri-butions and other situations . The calculated values with the new model are in good agreement with experimental data .When the number of data points decreases and the distribution of data points changes ,the new model maintains a hign accuracy and pres-ents a better numerical stability than other models .关键词
