请高手帮我翻译下： 选取5种不同的chinese herbal extract powder进行重复测试， 每个样品的测试不少于8次， 对数据进行离群值分析和取舍。检验离群值取舍的统计方法有很多种，本实验选用Dixon法， 对测定最大值( )和最小值( )的检验式分别为: 式中: 为测定值，n为以1为增幅依次增大的自然数；D1 为最小值的校验值；Dn 为最大值的校验值。设显著性水平α为0.05%，查得D0.05，8为0.554[10]。若确定D小于D0.05，8，则予以保留，认为测定结果中没有离群值。离群值分析和取舍结果见表4。 由表4可见，D1和Dn 均小于D0.05，8，没有出现界外值，说明在95%的置信度水平下，测试结果满足实验方法的要求，因此确定这一测试方法可行。 |

Five different Chinese herbal extract powders are selected and at least 8 tests are conducted on each sample. Outlier analysis is performed on the data for attainment or discard. There are multiple statistical methods to analyse outliers for attainment or discard and in this experiment Dixon's method is used. The statistics for the maximum and minimum of the tests are respectively where x is the measured value and n is the integer number incremented by 1; D1 is the statistics of the minimum and Dn is the statistics of the maximum. Let significance level α be 0.05% and D0.05,8 is found to be 0.554 [10]. If D is smaller than D0.05,8, then the data values are kept and no outliers are found in the test data. The results of outlier analysis and data attainment/discard is shown in Table 4. From Table 4 it can be seen that both D1 and Dn are smaller than D0.05,8, with no outliers. This indicates that under the 95% significance level, the test results satisfy the requirements of the experiment and therefore the test method is considered as appropriate. 注： x 在原文列无显示 供参考 |
