The composi tional change profiles of monazite demonstrate a heterogeneous distribution of e lements La, Ce, Nd, P, Th, Si, Ca and U. This was caused by the differences in geological environments, temperatures, pressures and compositions of the hy drothermal solutions.

根据微区剖面(0.18mm)元素分布曲线，指出了La、Ce、Nd、P、Th、Si、Ca和U等元素表现出8～10个微环带成分不均匀分布的特点，并认为成矿溶液的地质环境、温压和微量元素含量变化是不均匀分布的主要原因。

In the end, it is further developed of the inverse U hypothesis from monocycle condition to multi-cycle condition with a new hypothesis, which is called cyclical fluctuation of regional disparity.

在新古典经济学得出的增长轨迹基础上，利用简化的两地区逻辑曲线初步证明"倒U假说"的成立；并进一步讨论这一假说在多周期情形下的一个拓展，即地区差距的周期波动。

You don't want to give your baby a beautiful and well thought out full name, only to later discover that the monogrammed handkerchiefs will read "P.I.G" or Y.U.K.

"你不想让你的小孩一个美丽而周详的全称，只是后来发现monogrammed手帕将改为"p.i.g"或"y.u.k。

SHRIMP technique is applied to the age determination of Shuiquangou alkalic complex. Zircons from monzonite and syenite of the complex in the Dongping and Hougou gold mining district are dated at age of (390± 6) Ma and (386±6) Ma, respectively with U-Pb method. Rock-forming times of the complex is confidently constrained in the Late Caledonian-Early Hercynian period.

采用先进的SHRIMP测年技术对河北水泉沟碱性杂岩体进行了年龄测定，获得东坪金矿区水泉沟岩体二长岩锆石U-Pb年龄为(390±6)Ma，后沟金矿区水泉沟岩体正长岩年龄(386±6)Ma，比较可信地确定了水泉沟岩体的成岩时代为晚加里东期－早海西期。

High transmission of U、V lights transmission rate of SDI Mylar film is 90%, ordinary glass is 85% and common Mylar film is ......

U、V光透射性高（SDI麦拉膜的透射性为90%左右，普通玻璃为85%，而一般麦拉膜为60%左右）。

And let U be an open neighborhood of M in V and Δn be the n dimensional standard simplex in R n.

设U是M在V中的某开邻域且Δn 是Rn 中n维标准单形。

A shell graph of order n denoted by H(n,n-3) is the graph obtained from cycle C_n of order n by adding n- 3 chords incident with a common vertex say u.

一个有n个顶点的贝壳图H(n，n-3)，是通过在顶点数为n的圈C_n上一个公共点u上增加n-3条边得到的图。

In [29], the author gave that let G be a 2-connected graph with order n and S ≥ t, if |N ∪ N|≥ n - t for any nonadjacent vertices u and v in G, then G is pancyclic or n = 2t, G ≌ K_.

在[29]中，作者给出定理：设G是一个n阶2-连通图，且δ≥t，若对G中的任意两个不相邻的点u和v有|N∪N|≥n-t，那么G是一个泛圈图或n=2t，G≌K_。

To prove one edge union of k-shell graph is cordial, firstly fix the labeling of vertex of common edge(label u with 0 and v with 1), then according to the value of the graph order n module 4 to class the k shell gaphs to four cases, and to divide to small cases in every shell graph.

本文研究k-贝壳图的亲切标号时，在固定了公共边上的点的标号(对u标号0且v标号为1)之后，我们采用如下方法：首先，以每个贝壳图的顶点数对4取模的余数来分类，这样就得到了四种(来源：d1ABC论文网www.abclunwen.com)不同情况的贝壳图；然后在每个贝壳图中再分情形进行标号；最后，通过证明得到这种标号方法是满足亲切标号的定义的，从而证明了k-贝壳图的亲切性，成功的解决了Sethuramam和Selvaraju猜想，证明了其正确性。

The split between the two groups can hardly be papered over.
