在地质勘探工作中,为了经济起见,往往将几个经过加工后的部分副样合併起来,进行化验分析-通称组合分析,以便了解其中某些次要的有益或有害元素的含量.至于对每个参予组合的样品,应各取(注1)多少重量,才能使组合后的样品恰当的反映出组合部分所代表矿体的平均样,则是个值得探讨的问题.某些书(注2)上说:用以组合的样品重量应与其原始萤最成正比.也有另一些书(注3)上说:用以组合的样品重量应与其采样长度成正此.更有些书(注4)上说:用以组合的样品重量应与其原始重量或采样长度成正比.但其理由何在,哪个适用,缺乏论证.作者拟分别下面几种情况,加以论述.
In the geological exploration work, for the sake of economy, some processed samples are often combined for laboratory analysis - commonly known as portfolio analysis in order to understand some of these secondary beneficial or harmful elements. It is worth discussing how many samples should be taken in order to make the combined sample properly reflect the average sample size of the representative ore body in the combination part. ) Says that the weight of the sample to be combined should be the most directly proportional to its original weight. There are also other books (Note 3) where the weight of the sample to be combined should be positive with its sample length. Said: the combined sample weight should be proportional to the original weight or length of the sample.But the reason why, which applies, the lack of argument.The author intends to discuss the following situations, respectively.
