An element bonding parameter topological index HLA is proposed based on topological principle and valence shell electron structural character.

基于元素键参数拓扑指数原理以及镧系元素价层电子结构特征构建了一种新的拓扑指数HLA。

A new element bonding parameter topological index H_ is based on H_E.

在元素键参数拓扑指数 HE的基础上定义了一个新的拓扑指数HER并与镧系元素的11种物理化学性质显示高度的线性相关性。

The ability of HBMPPT-S-Toluene-HNO〓 system to extract lanthinideelements was much lower than its ability to extract trivalent Am.

该体系对各镧系元素之间也有一定的分离效果，但相邻镧系元素间的分离系数较小。

Trivial Solution conception is put forwarded based on the theorem of K〓nig and forbidden node----for the n×n 0-1 degeneracy matrix, the solution under the condition that all element 1 can not be covered completely by n lines that must have intersects or can be covered completely by n lines that must have cross, without forbidden node, are called TS matrix.

本文在K〓nig定理和禁点定理的基础上，提出了平凡解的概念，即对于n×n阶的退化矩阵，全部1元素不可能被n条有交叉的直线全部覆盖或能用n条直线覆盖全部1元素，但无禁点的情况称为平凡解。并证明了如下的平凡解产生的充分必要条件：对退化矩阵A〓，若

Ultimate analysis provides an useful inventory of the distribution of the major elements in humic substances.

元素分析提供腐殖物质中主要元素分布的有用资料。

The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.

1稀土元素配分模式与玄武岩类似；(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集，而配分模式的相似性反映了火山物质来源与玄武岩具有同源性；(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式，说明界线粘土岩成因也不同于煤山剖面的界线粘土；(4)大量的玄武岩岩屑；(5)Ti元素的富集；(6)亲铁元素Ni和Co含量较低，特别是在界线异常层含量降低，表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件，这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。

Native element: Any of the 19 chemical elements that occur as minerals and are found in nature uncombined with other elements.

自然元素：以自然状态存在于矿物中，不与其它元素结合的十九种化学元素。

One common strategy is to preallocate a block of raw memory to hold unconstructed objects. When new elements are created, they could be constructed in one of these preallocated objects. When elements are freed, we'd put them back in the block of preallocated objects rather than actually returning memory to the system.

一个通用策略是预先分配一场原始内存来保存未构造的对象，创建新元素的时候，可以在一个预先分配的对象中构造；释放元素的时候，将它们放回预先分配对象的块中，而不是将内存实际返还给系统。

The union of any two sets consists of those elements that are in one or the other or in both given sets; the intersection of two sets consists of those elements that are in both given sets.

任何两个集合的并集包含了出现于这两个子集中某一个集合或同时出现于这两个集合中的所有元素；两个集合的交集包含了同时出现于这两个集合中的元素。

The Aristotelian view of the elements survived until the 17th century, when Robert Boyle proposed a theory of "primitive and simple, perfectly unmingled bodies," many more than four, that combine to form chemical compounds.

亚里士多德学派的元素观一直存在至十七世纪，直到罗伯特。波义耳提出了"原初的、简单的、绝对纯净的小体"理论——远远多于四种元素构成了化学混合物。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
