摘要
介绍了红外光谱经过处理 ,利用偏最小二乘法同时测定内燃机油中添加剂含量的方法 ,并对测定结果的准确性、可靠性进行了验证。这种方法便捷 ,准确度、精密度优于现行方法 ,可明显提高分析化验效率并降低检验成本 ,为生产监控和产品鉴别提供了强有力的手段。推广使用后效果显著。
The method of determining the additives content in internal combustion engine oil with leaning least square method while the infrared spectrum was analyzed was described.The accuracy and reliability of determining result were verified,indicating that this method can improve the analytical efficiency and reduce remarkably the inspection cost,with superiority over available methods in accuracy.It is helpful for production supervision and products discrimination with good application effects.
