摘　　要：为统计某型柴油机润滑油原子发射光谱分析经验阈值,文章汇总了同型装备历史监测数据,通过直方图分析了各元素质量分数样本分布规律。结果表明,绝大多数元素质量分数样本分布与理想正态分布相差甚远,不满足传统阈值确定方法的使用条件。文章针对几种典型分布样本,基于样本分布特点采用不同方法进行数据处理,并统计经验阈值。最后,将所确定的经验阈值与传统方法阈值作比较,并结合工作实践就阈值的合理性进行了分析。分析表明,文中方法确定的经验阈值更为合理。In order to calculate the empirical thresholds of the atomic emission spectrum of lubricating oil for a diesel engine,this paper collects the historical monitoring data of the same diesel engine,and analyzes the mass fraction distribution laws of different elements by histograms.The results show that most of the distributions are far from the ideal normal distribution and dissatisfaction with the prerequisite of the traditional method of determining the thresholds.According to the distribution characteristics,the article processes several kinds of representative samples by using different methods,and calculates the empirical thresholds.Finally,it compares the empirical thresholds with the thresholds determined through the traditional method,and discusses the rationality of the thresh⁃olds with working practice.The discussion shows that the empirical thresholds determined by the proposed methods are more reasonable.
