摘要
标准样品制备过程中,样品均匀性检验和定值检验是样品制备的关键。详细阐述了粮食行业标准样品——粳稻谷整精米率标准样品的制备过程中均匀性检验和定值中的数理统计方法,并通过实例对标准样品的标准值和不确定度进行计算。
In the process of preparation of reference material,the homogeneity test and the setting value test was very important.The mathematical statistics in preparation of reference material of head rice yield of japonica rice was described in detail,including the homogeneity test and the setting value test.The certified value and uncertainty of reference material was calculated and illuminated with a particular case.
