元素

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。

Of course, a periodic table cannot be complete unless it has the atomic mass of the element and so this table uses the rank of the web page as it's "mass".

当然，在元素周期表中，可以是不完整的，除非它拥有原子质量的元素，所以本表使用秩该网页，因为它的"地下"。

I was struck by the fact that the activity of uranium and thorium compounds appears to be an atomic property of the element uranium and of the element thorium .

我突然意识到，铀化合物和针化合物的这些活性似乎是元素铀和元素钍的原子属性。

The students can't catch on the essence of the relationship between the atomic structure and the element properties, and they often mistake the element's properties for the atomic's.

对"原子结构与元素性质的关系"存在着各种糊涂的认识，往往将单质的性质误认为是元素的性质。

Remember that smallest, deepest element I described earlier This is the atomic element—for a news site, it's the story page; for a search engine, it's the search result; for a store, it's a product page.

还记得我前面所提到的那写最细小最底层的元素吗这就最基础的元素——在一个新闻站上它就是详细的新闻内容页，搜索引擎中它就是结果的显示页，在产品目录中它就是详细产品页。

British physicist who determined that the atomic number of an element can be deduced from the element's x-ray spectrum.

莫斯利，亨利·格温·杰弗里斯1887－1915英国物理学家，提出一种元素的原子序数能够从这种元素的x光射线光谱中推断出来

The Ew of 94 neutral atoms and 109 ions were calculated by the essential parameters (mass, quantity of electricity, atomic or ionic radius and number of the outermost electrons).

较好地说明周期表中元素性质、离子性质及其周期性递变规律，可作为定量某些元素性质的基础数据，有一定的理论意义和应用价值。

Moreover, some subgroups of Aut are obtained, such asthe inner automorphism group, the central automorphism group, the involutional automorphism group, the first and the second extremal automorphism group.

证明了：当n=0时，Aut中每个元素都是内自同构，且Aut≌C(定理1.12)。n=1时，Aut中每个元素都是有限个内自同构，中心自同构，对合自同构和第一类外自同构的乘积(定理1.13)。

The automorphism groups of the two posets are given and the numbers of orbits of the automorphism groups are counted. At the same time, the number of words in every rank of the posets is obtained.

本章给出了偏序集P和Q的自同构群，计算了在各自的自同构群作用下轨道的个数以及每一轨道中元素的个数，得到了偏序集中每一秩中元素的个数。

The system mainly consists files and maps of basic graphics system, graphics elements (possess for processing point, the line, face, network graphic elements), the graphics operations (possess for blowing up graphics and dwindling graphics, movement, backdate and other operational functions), graphics import and export (possess for the mouse coordinate mapping,graphics data coordinate imported), conventions and the use of line-type, the son-graphics of filling the function module, to achieve the basic functions of the vector graphics.

本系统主要包括基本图形系统的文档和视图、图形元素（具备处理点、线、面、网络等图形元素）、图形操作（具备图形的放缩、移动、回溯等操作功能）、图形输入和输出（具备鼠标交互绘制、图形数据交互输入）、定制和使用线型、子图填充等功能模块，能够实现基本的矢量图形的所具有的功能。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
