摘　　要：用放射性同位素源激发小型能量色散Ｘ 射线荧光光谱仪对银饰品、餐具、摆件中的银含量进行无损快速定量测定， 在银含量为１０－０ ％ ～９９－９ ％ 的范围内， 测定精度和准确度均能满足实际检测误差要求。测定结果与大型的波长色散型Ｘ 射线荧光光谱仪一致。A method for the determination of silver content in jewelries, tableweres and furnishing articles with small _ sized radioisotope _ excited energe dispersion X _ ray fluorescence spectrometer is reported. The method is nondestructive and rapid. It is able to meet the practical requirement of accuracy and precision when silver content is in the range of 10.0%～99.0%. Results are accorded with results of determination by biger _ sized wavelength dispersion X _ ray fluorescence spectrometer.
