摘　　要：研究了微波消解润滑油的体系和程序,并对ICP测试条件进行了选择,确定了微波消解-ICP法测定润滑油中硫含量的方法,采用本方法硫元素检出限为0.0003%,标准曲线线性相关系数达到0.999909以上,试验精密度高,测试结果准确。The systems and procedures of microwave digesting lubricants were studied, and test conditions for ICP were selected. The microwave digestion - ICP method of measuring sulfur in lubricants was determined. The detection limit of sulfur is 0. 0003% by this method. The linear correlation coefficient of the standard curve is above O. 999909, The test is high precision, and test results are accurate
