Thus the sample size can be increased, and the nugget effect and detection limits can be decreased compared with normal Carius tube technique. This new technique is capable of digesting 12 g samples in a 75 mL Carius tube with 35 mL aqua regia at 320℃, and Re and all the PGEs can be measured.

由此可以加大取样量，降低铂族元素测定过程中的块金效应及检出限，使超低含量铂族元素的测定成为可能。12g样品在75mL卡洛斯管中用35mL王水于320℃溶解15h，基本上可以使各种地质样品中的铂族元素矿物完全溶解。

A descendant selector of the form "A B" matches when an element is an arbitrary descendant of some ancestor element .

当是 祖先元素的任意代的后代元素时，"A B"这样格式的选择器匹配元素B。

The bottom margin of an in-flow block-level element is always adjoining to the top margin of its next in-flow block-level sibling, unless that sibling has clearance.

浮动的块级元素的 margin-bottom 总是与它后面的同级浮动块级元素的 margin-top 相邻，除非那个同级元素已经使用了清除。

For lanthanides in Am at pH 2. 7～2. 8. According to empirical distribution ratio model and proposed calculation method, flow sheets are proposed for the separation of Am and fission product lanthanides from power reactor and production reactor waste respectively.

7级萃取、3级洗涤2级反萃的多级逆流分馏萃取实验表明HBTMPDTP-TBP-煤油能够很好地萃取分离镅和镧系元素，在pH值为2.7～2.8时，镧系元素中镅的分离系数大于5×10〓，镅中镧系元素的分离系数大于2.5×10〓。

A second version of assign takes an integral value and an element value. It replaces the elements in the container by the specified number of elements, each of which has the specified element value

assign 运算的第二个版本需要一个整型数值和一个元素值做参数，它将容器重置为存储指定数量的元素，并且每个元素的值都为指定值

The pollution of As results from the copper deposits, the lead-zinc deposits and limonite, and from their exploitation; the pollution of Cd is related to lead-zinc deposits, the exploitation, and agricultural irrigation with waste water; the pollution of Pb and Zn are mostly ascribed to the lead-zinc deposits and related exploitation.

As元素污染的主要原因是铜矿、铅锌矿褐铁矿矿床及其开发；Cd元素的污染与铅锌矿床及其开发，以及农业污灌有关；Pb、Zn元素的污染与铅锌矿床及其开发密不可分。

If the type of the substitutable element is the same as the type of the head element you will not have to specify the type of the substitutable element.

如果替代元素的类型和标题元素的类型相同，你就不需要再指明替代元素的类型了。

The physicochemical properties, fatty acid composition and mineral elements of Viburnum cylindricum seed oil were determined. The results showed that 20 kinds of fatty acids in the Viburnum cylindricum seed oil were identified, in which the main components were oleic acid (33.34%), 8,11-octadecadienoic acid (28.24%) and palmitic acid (22.55%); the seed oil contained 6 kinds of essential mineral elements including Ca, P, Mg, Fe, K and Mn, and their contents were in the reasonable range of body requirement.

测定了水红木油的理化指标；用GC/MS法测定了脂肪酸组成及含量，共检出20种脂肪酸，主要成分9-十八碳烯酸占33.34%，8，11-十八碳二烯酸占28.24%，十六烷酸占22.55%，3种脂肪酸共占84.13%；用ICP-OES法测定了矿质元素的种类和含量，检出的Ca、P、Mg、Fe、K、Mn 6种矿质元素均为人体必需元素，含量均在人体所需合理范围内。

The volumetric method is also used in the measurement of the base metal and the principal elements in the high Cr cast iron and the electrooptical spectrographic method for determination of multi elements in the high Cr cast iron is established by choice of certain basic elements as the internal standard,by correction of the base spectral line and the interfered spectral line and induced correction and blank correction of the material as well as by drawing up the correction curves.

采用容量法测定高铬铸铁中基体及主要元素的含量，通过选用基体元素作内标，对谱线进行基体和干扰校正以及材质的诱导校正和空白校正，绘制校正曲线，建立了光电光谱法测定高铬铸铁中多种元素的方法。

Re is moderately incompatible element, while Os is highly compatible. As they are highly siderophile, ReOs isotopic system can provide unique insight in dating and tracing research compared to other longlived radiogenic isotope systems (e.g. RbSr, SmNd, UThPb ) which involve lithophile elements partitioning into silicate rather than metal or sulfide.

Re为中等不相容元素，Os则属强相容元素，与母子体均为不相容元素的RbSr、SmNd、UThPb等同位素体系相比，具亲铁、亲硫性的ReOs同位素体系在定年和示踪研究中显示出特殊性，受到了地学家高度重视，其应用正走向普及。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
