摘要
本文讨论了多份采样法在特定批煤采样精密度核对的相关问题,结合采样精密度核对示例,提出了正确核对特定批煤采样精密度和反算初级子样方差的方法。
In this paper, the problems related to the precision of sampling checking of particular lot by replicate sampling method are discussed. A method for correctly precision of sampling checking of particular lot and calculating the variance of primary sample is proposed with an example of sampling precision checking.
