摘　　要：柴油机机油中金属元素的成分和含量的变化蕴涵着各摩擦副润滑、磨损和工作状态的丰富信息,但是,柴油机运转过程中的频繁换油影响了元素浓度变化的趋势。通过对换油后Fe浓度曲线进行线性回归,在系统中排除了换油后的浓度变化的影响,从而为柴油机的磨损趋势和故障趋势的研究提供了保证。The changing of the composition and concentration of the engine oil in diesel engine indicates the lubrication, wear and estate of all the friction pairs. At the same time, the high frequent oil changing during the operating of the diesel influences the changing current of the element concentration. Through linearity regression to the concentration curve of Fe,it gets rid of the influence of the concentration changing, and it ensures the current research of wear and tailure.
