查询词典 trace elements

The mineralogy, petrology, rare earth and trace element geochemistry, Re-Os and Sr-Nd isotopic geochemistry of the black shales and cherts of Yuretusi Formation at the bottom of the Cambrian in Xiaoerbulake and Shugeitebulake sections from northern Tarim Basin have been systematically studied. It was discovered that the high enrichment of some deep source metal elements in the black shales deals with the activity of hydrothermal fluid from the lower crust or upper mantal.

本项目对塔里木盆地北部肖尔布拉克和苏盖特布拉克两剖面下寒武统底部玉尔吐斯组富有机质黑色页岩和硅质岩的矿物学、岩石学、微量元素、稀土元素、Re-Os和Sr-Nd同位素地球化学进行了系统研究，发现该黑色页岩中部分深源金属元素的高度富集与来自盆地下部上地幔或下地壳的深部物源的热水流体作用有关。

From the connotation of Derrida's différance and the language point of deconstructionism, a phenomenon can be found that the component sign of any language is not self-sufficient, but has a complex relationship with other elements involved, not only possesess the trace of other signs, also has their unique differences, which outstands their own value when forming the differences.

从&异延&的内涵和解构主义的语言观可以看出：任何语言符号的组成要素都不是自足的，而是与周围其他成分有着漫无头绪的复杂关系，既带有其他符号的印迹，但又彼此有别，并在形成差异时突显自身的价值。

The method for catalyst copper analysis was established, in which an effective measurement of trace content of elements with incremental mode by X-Ray diffraction fluorescence spectroscope was introduced.

建立了采用X射线衍射荧光光谱仪、过增量法测定铜催化剂中微量元素含量的方法。

Gold ore contains only trace amount of valuable elements,and yielding much more tailings after pro- cessing and metallurgy than other metals ore.

黄金矿石有价元素含量很少，经选冶后产生比其它金属矿石更多的尾矿。

In addition, the abundance of part of trace element in the otoliths possibly has the good relevance with the responding elements in water. Through the analysis of micro-chemistry characteristics of the wild carp otoliths, the waters environment condition that wild carps live in should be possible reflected.

此外，耳石中部分微量元素的丰度与各自水体的特征可能存在较好的相关性，利用野生鲤鱼耳石的微化学特征应该可以反映其所生活水域的环境状况。

We trace back to the history of philosophical inquisitions and scientific research for matter structure, and point out that quarks are the basic elements of matter.

追溯了物质结构的哲学探讨与科学探索，指出了夸克是物质结构的最小单元，从而揭开了物质结构之谜。
