摘要
１９８６～１９９６年间我国研制了两批共６个海洋地质标准物质：３个多金属结核标准物质ＧＳＰＮ－１～３和３个深海沉积物标准物质ＧＳＭＳ－１～３，形成了两个标准物质系列。与美国、俄罗斯、印度和日本的同类标准物质相比，这些标准物质的主要特点是：①实用性强：这些样品主要取自世界上锰结核最富集、也是各国“先驱投资者”开辟区最集中的太平洋ＣＣ区；②系列性好：这些样品还可与美、俄的标准物质构成既具有较大的元素浓度范围又具有适当浓度梯度的标准系列；③被测定组分多（达７９个），定值组分达６３个。其中包括５８个组分的保证值和５个组分的参考值，全组分的加和均在９９５％～１００１％之间；④参加合作的国家数和实验室多：有１８个国外实验室和包括台湾大学在内的１４个国内实验室参加了合作分析。这就使这些标准物质具有较大的国际影响。
A brief introduction to six marine geological reference materials prepared by China during 1986～1996 was given.It includes three polymetallic nodule reference materials GSPN—1～3 and three deep sea sediment reference materials GSMS—1～3 and these reference materials formed two good reference material series.Comparing with the same kind of the reference materials of America,Russia,India and Japan,the main features of the reference materials as follows:①The reference materials are practical because the samples were taken from the Pacific Ocean CC(Clarion Clipperton fracture)zone,being mostly rich in manganese nodules in the world and focusing most pioneer areas of “pioneer investors”.②A complete standard sample series with certain content range and proper content gradient can be formed together with the reference materials of America and Russia.③79 constituents were determined and the values of 63 constituents,including recommended values of 58 constituents and the proposed values of 5 constituents,were certified.④14 Chinese laboratories(including Taiwan University) and 18 foreign laboratories from England,France,German,Russia,Czech,Canada,India and Pakistan took part in the collaborative analysis.These features make the reference materials have a great international impact.
