摘要
通过导入正态分布函数,证明标准化后的样本化验数据服从标准正态分布,完成了对化验室数据从定性评价到定量分析的转变,并用具体计算举例说明了该方法对化验数据进行甄别的显著作用。
Though lead in a normal distribution function,we prove that the laboratory data after standardization,obey the standard normal distribution,the completion of laboratory data from the qualitative to quantitative analysis of changes in assessment and use specific examples to illustrate the significant effect of calculation method to screen-ing laboratory data.
