放射性元素

The content of radioactive elements in sediment is related to the scale of sediment granularity and lithology, being high in argillaceous sediments e.

同时，放射性元素含量的高低还与古气候环境有关，温暖潮湿的环境放射性元素含量较高，凉爽干燥的环境含量较低。

Any element having an atomic number greater than 92; all are radioactive.

原子序数在以后的元素，都是放射性元素。

The characters of geochemistry are rich alkali. And at the same time the content of calcium is high. They are rich in alkali, high in Potassium, enriched in LILE, LREE and Pb, depleted in HFSE and have a small Sr, Nd, Pb isotope range. Their source is probably a kind of even metasomatic mantle. This is consistent with the fact that there is kimberlite containing flogopite in the deep-source enclosure of Cenozoic super-K alkali lava in the southern part of this rock zone.

组成这些钾质碱性岩带的岩石：在岩相上，包括深成相、浅成相和喷溢相等不同岩相；在岩性上，从超基性、基性、中性到酸性岩石；造岩矿物，从超基性到酸性岩石中均有透辉石，在基性、超基性岩中有霞石；在岩石化学成分上，所有岩石均表现出富碱高钾富钙，微量元素富集Rb、Sr、Ba等大离子亲石元素和Th、U等放射性元素，贫Nb、Ta、Zr、Hf等高场强元素；稀土元素富集轻稀土，铕负异常不明显；Sr、Nd、Pb同位素组成，显示了物质来源于富集地幔源区。

A formula for non-dimensional synthetic electronegativity was obtained by multiple regression analysis. The correlation coefficient (R=0.9844) and test of significance Sig.

采用回归分析法，对周期表中除零族、氢及放射性元素之外的77种元素的Pauling电负性X(下标 P进行回归分析，得到了一个无量纲的综合性的电负性计算公式，相关系数(R=0.9844)和回归方程F检验的显著性水平Sig。

Experts noted that the current urban living environment is the main source of radioactive hazards of indoor radon and radioelement content standard building materials.

专家指出，目前城市生活环境中主要放射性危害的来源有室内氡气及放射性元素含量超标的建筑材料等。

Radon is the crust of rock, soil radioelement arising from the decay of a radioactive inert gases, which are mainly the lungs and bronchial have on the human body radiation.

氡是地壳岩石、土壤中放射性元素衰变而产生的一种放射性惰性气体，它主要是对人体的肺和支气管产生辐射作用。

One, in fact, almost all taken from the natural rock, used to bake the tiles in the soil, more or less contain a certain amount of radioelement, of course, will not cause radioactive danger, when more than a certain amount of radioactive material, would pose a threat to human health.

一、事实上，几乎所有采自大自然的岩石、烧制瓷砖用的泥土等，或多或少都含有一定量的放射性元素，当然，并非都会对人体造成放射性危害，只有当放射性物质超过一定数量时，才会对人体健康造成威胁。

My Marie Curie (1867-1934) French nationality Polish scientists to study the phenomenon of radioactive found radium and polonium two radioelement, twice the life of Nobel Prize.

居里夫人 Marie Curie（1867-1934）法国国籍波兰科学家，研究放射性现象，发现镭和钋两种放射性元素，一生两度获诺贝尔奖。

Factor analysis was employed to reduce the number of parameters deduced from multiple radiometric methods. The derived principal components f1, f2 are undependent with each other and of identified geological means. The trend analysis on f1 and f2 was conducted to extract the remainder anomalies which reflect the radioactivity elements enrichment formed by fracture structures and locate the spatial positions of thermal underground water.

对于由多种放射性方法造成的多参数，采用了因子分析方法以降低参数量，组成互不干扰而地质意义明确的主成份分量f1、f2，继而对f1、f2进行趋势分析，提取了由构造断裂造成的的放射性元素富集的剩余异常，圈定出地下热储的空间位置。

The neutrinos are used for fundamental physics experiments, but the proton beam that is produced at the start (this hits the target rod at the beginning of the simulation you download) is also going to be used in experiments for neutralising radioactive waste by transmuting the radioactive elements into stable ones.

中微子使用为根本物理实验，但导致在开始的氢核射线(这击中目标标尺在模仿开始您下载)并且被使用在实验为中立化放射性废物由transmuting 放射性元素入槽枥一个。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
