摘　　要：应用 X射线荧光光谱法对 PET塑封金制品的金层厚度进行了测试。通过一定的技术和计算机处理 ,采用合适的数学模型 ,使不同厚度不同型号的 PET塑封金层得到不同的校准曲线 ,从而求得 PET塑封金制品的金层厚度。测试结果与经典称重法结果比较 。This paper introduces thickness measurement of gold film of PET sealed gold products by XRF (X Ray Fluorescence Spectrometric) method. Through specific technical operation and computer processing, adopting appropriate mathematical model, we could get different calibration curves (for different thickness and type of PET). Thus, thickness measurement of gold film of PET sealed gold products could be made. Compared with the results from typical method (weighting method), this method is proved feasible.
