	本文研究了用紫外荧光法测定石油产品中硫含量的准确度与精密度。硫含量范围在1~10 mg/kg和10~100 mg/kg的浓度范围内线性关系均良好，r = 1。对50批次汽油、柴油、航煤进行硫含量测定，紫外荧光法的相对误差有45批次在±3.8%以内，而能量色散X射线荧光光谱法的相对误差是紫外法的几倍甚至几十倍，准确度低，紫外法的精密度低于3.44%。结果表明，紫外荧光测硫仪测石油产品中的硫含量具有较高的准确度和精密度。<br />
This paper studied the determination of the accuracy and precision of sulfur content in petroleum products by ultraviolet fluorescence. Sulfur content exhibited good linearity with the regression coefficients 1 at the concentration ranged from 1 to 10 mg/kg and from 10 to 100 mg/kg. For de-termination of sulfur content in 50 batches of gasoline, diesel and aero coal, the relative error of ultraviolet fluorescence is within 45 batches of less than ±3.8%. The relative error of the energy dispersive X-ray fluorescence spectrometry is several times or even dozens of times than the ul-traviolet fluorescence method. The accuracy is low, and the precision of ultraviolet fluorescence method is less than 3.44%. The results show that the sulfur content in petroleum products is high accuracy and precision measured by ultraviolet fluorescence.
