能否帮忙翻译一下?

快乐老家

  • 那位高手帮忙翻译一下METHOD 3060A中的一个片断,本人在理解时存在一点障碍,谢谢!
    8.5 Both soluble and insoluble pre-digestion matrix spikes must be analyzed at a
    frequency of one each per batch of < 20 field samples. The soluble matrix spike sample is spiked
    with 1.0 mL of the spiking solution prepared in Section 5.8.1 (equivalent to 40 mg Cr(VI)/Kg)) or at
    twice the sample concentration, whichever is greater. The insoluble matrix spike is prepared by
    adding 10-20 mg of PbCrO (Section 5.6) to a separate sample aliquot. It is used to evaluate the 4
    dissolution during the digestion process. Both matrix spikes are then carried through the digestion
    process described in Section 7.0. More frequent matrix spikes must be analyzed if the soil
    characteristics within the analytical batch appear to have significant variability based on visual
    observation. An acceptance range for matrix spike recoveries is 75-125%. If the matrix spike
    recoveries are not within these recovery limits, the entire batch must be
    rehomogenized/redigested/reanalyzed. If upon reanalysis, the matrix spike is not within the recovery
    limits, but the LCS is within criteria specified in Section 8.3, information such as that specified on
    Figures 1 and 2 and in Section 3.1 should be carefully evaluated . The Cr(VI) data may be valid for
    use despite the perceived "QC failure." The information shown on Figure 1 and discussed below
    is provided to interpret ancillary parameter data in conjunction with data on spike recoveries.

    我昨天翻译了一下,感觉不是很通顺。如果这位朋友很着急的话,我先跟贴,可以参考一下。等别人再来帮助修改一下!


    8.5 不管是可溶的,还是不可溶的前处理基质添加分析,每一批必须分析不多于20份田间样品。可溶的基质添加分析样品用1.0ml的基质溶液按照5.8.1步骤准备(等同于40mg Cr(VI)/kg)或者相当于样品的两次浓缩,不管哪一种方法都包括市区及郊区的样品;不可溶的基质添加分析样品通过加10-20mgPbCrO4(步骤5.6)去平分样品。这个是用来估算消化过程中的分解。 然后所有的基质添加分析按照步骤7.0进行消化。在分析批量中,如果土壤的特征能够很明显的辨认出有变化,那么就需要进行更频繁的基质添加分析。基质添加分析可接受的回收率在75-125%,如果回收率不在这个范围,那么整批样品必须重新再混匀,再消化,再分析。基于上面的再分析,如果基质添加分析还不在回收范围,除了8.3步骤中指定的标准中的LCS,还要仔细考虑诸如图1和图2以及步骤3.1等中提到的信息。虽然“质控失败”,但是Cr(VI)的数据是可信的。图1显示的信息,和下面讨论的是用来辅助说明在基质添加分析回收中涉及到的相关参数数据。

    heavenli你也不来看一下。有人给你翻译了,太不厚道了。
