摘　　要：船舶柴油机过磨合期后,各摩擦副发生早期磨损时,由于磨损量不大,润滑油中各金属元素数值未超过检出限值,分析人员可能会认为设备磨损正常,超出检出限值时,经验少的技术人员对于分析定位磨损颗粒元素来源不确定。文章通过对船舶柴油机油液光谱数据的分析,发现相关系数法可以有效解决上述问题,为相关系数法在船舶柴油机以油液分析技术为手段的故障诊断中提供了一种新的应用。When early wear occurs at the friction pairs after the running-in period of a marine diesel engine,because the wear loss is not large,and the values of various metal elements in lubricating oil do not exceed the detec⁃tion limit.The analysts may determine that the wear is normal.When it exceeds the detection limit,less experi⁃enced technicians are uncertain about analyzing and locating the sources of the elements of wear particles.By analyz⁃ing the oil spectrum data of marine diesel engines,this paper finds that the correlation coefficient method can effec⁃tively solve the above problems,which provides a new application for the fault diagnosis of marine diesel engines us⁃ing oil analysis technology.
