摘    要:采用直方图频率说明、参数分布拟合假设检验、非参数密度估计等多元统计技术,研究了铅、镉、汞、砷在不同动物源性产品中的分布特征,通过非参数方法给出了4种元素在不同产品中的密度分布函数曲线和经验分布函数曲线,以此解释了元素的分布特征,掌握了重金属的累积富集规律。

关 键 词:多元统计  重金属  动物产品  分布特征

Abstract:Distribution of lead, cadium, mercury and arsenic in different animal products was studied by multivariate statistical technique of frequency histogram, parameter distribution test of hypotheses and non-parameter density estimate. Function curves of density estimate and empirical distribution of four kinds of elements were given, which explained the distribution of elements. The regular of heavy metal cumulation and enrichment was grasped.
Keywords:multivariate statistical analysis  heavy metal  animal product  distribution characteristic
