| 摘 要： | 根据均匀性研究和定值分析的统计参数，提出了一个用于估计最小取样量的公式：Mm=Mk（Ssk/FαSchar^2）.本方法可以避免为最小取样量的估计另外设计试验，既避免了大量的财力物力消耗，又改变了直接用均匀性检验的称样量做最小称样量的不合理性。 |

| Abstract: | Based on uniformity research and statistical analysis of fixed value, a formula for estimating the minimum count of sampling is proposed as Mm=Mk（Ssk/FαSchar^2） In this way it could avoid launching additional experience with purpose of estimating rain count of sampling, which saves lots of expenditure as well as avoids using the sampling count of uniformity test as the rain sampling, which is in fact unreasonable. |
| Keywords: | ferroalloy min count of sampling uniformity of RM statistical estimation |
