主要元素

In addition, Cd and Tl are the potential toxic elements in the supergene environment; therefore, their isotopic composition could be used to trace the source of contamination.

另外，Cd，Tl是环境污染的主要潜在元素，因此采用稳定同位素示踪还可能示踪表生环境中的污染来源。

The results of the dissertation were concluded as follows:(1) It is essential to deposit a basic additive on the Mo-based catalysts for the synthesis of CH_3SH. The potassium-doped Mo-based catalysts exhibit the highest activity than that of the catalysts doped with the otherⅠA andⅡA group basic promoters. H_2-TPR and LRS characterizations suggest that the addition of a base leads to the transformation of octahedrally coordinated Mo to tetrahedrally coordinated Mo, thus leads to the split of low temperature reduction peaks. The interaction between the basic components and Mo lead to the formation of B-Mo interface phase, which are closely correlated with the formation of CH_3SH.(2) It has been found that Fe, Co, Ni and Te have evident promoting effects for the K-Mo/SiO_2 catalysts.

主要结果归纳如下：(1)在Mo基催化剂中，必须添加碱才具有可观的合成甲硫醇活性，在IA和IIA族元素中，K是最佳的碱促进剂，当K/Mo摩尔比为2，前驱体为K_2CO_3，采用共浸法制备的K-Mo催化剂活性最高。H_2-TPR和LRS表征显示，碱的加入导致表面八面体钼氧物种向四面体转化，催化剂的低温还原峰发生分裂，碱助剂与钼之间存在强相互作用形成了B-Mo"界面相"，该物种与合成甲硫醇密切相关。

He primary visual element in the T-Mac's design is the modified shell-toe element that covers the toe of the shoe and then wraps around and into the midfoot.

-Mac 设计上能看见的主要的元素就是覆盖鞋头，包裹周围，伸入中掌的改良的贝壳头。

Combining with the production control of low-alloy steel with niobium , the main reasons of surface transverse crack of low-alloy steel slab with niobium were put forward.

介绍了铌元素的作用和行为及在常见钢种中的作用，结合含铌低合金钢的生产控制，分析出造成含铌低合金钢连铸坯表面产生横裂纹的主要原因，并采取相应的技术措施，提高铸坯表面质量。

The protoliths of the chlorite-actinolite schist were mainly volcanic-sedimentary rocks enriched in basalt. The chlorite-actinolite schist and the altered pillowbasalt are characterized by high contents of TiO5, P2O5 and MgO, LREE-enriched patterns with negative Eu anomalies, and "tumescence" patterns for trace elements with enrichment in Nb, Ta and Ti; these are typical characteristics of "OIB-type" alkaline basalt.

绿泥阳起石片岩的原岩主要为富含玄武岩的火山－沉积岩系，绿泥阳起石片岩和蚀变枕状玄武岩具有TiO2、P2O5、MgO含量较高和LREE富集型、无Eu异常，以及"大隆起"微量元素配分模式和富集Nb、Ta、Ti元素等地球化学特征，显示为较典型的洋岛型碱性玄武岩性质。

This is mostly for simplicity's sake, but pairs are by far and away the most commonly used size of tuple.

虽然这主要是为了简化，但2个元素的元组确实是被使用最多的一种元组。
