摘要：

对不同温度下煤焦油样品中的硫含量进行测定，结果表明：硫含量的平均值随温度的升高而变大。最大标准偏差为0.002 29％，最大变异系数为0.559％，但不同温度下所测样品的精密度是一致的。建议样品温度保持相对恒定，减少温度变化对硫含量测定结果带来的影响。

Abstract:

The sulfur contents in coal tar samples under different temperatures are determined.The results showed that the average value of the sulfur content increases with rising temperature,with maximum standard deviation 0.002 29% and maximum coefficient of variation 0.559%.The precisions of the samples measured under different temperatures,however,remain consistent.It is suggested that the sample temperature should be relatively kept constant to minimize the impact of the sample temperature variation on the determination results of the sulfur content.
