In three cases, we investigate the decomposition of a polynomial f=x~n -u in a local field to factor a prime ideal of K in its extension.

在这三种情况下，我们研究多项式f=x~n－u局部域上分解情况，得出相应K上素理想具体分解形式。

The geochemical characteristics of basic to intermediate-basic igneous rocks indicate that they belong to a tholeiite suite. Their chondrite-normalized REE patterns are of nearly flat and slightly LREE-enriched type, and their primitive mantle-normalized and MORB-normalized trace element spidergrams are generally similar; the LILEs Cs, Ba, Sr, Th and U are enriched, while Rb and K and the HFSEs Nb, P, Zr, Sm, Ti and Y are depleted. All these show comagmatic evolutionary and genetic characteristics.

基性—中基性岩浆岩的地球化学特征表明其属于拉斑玄武岩系列，稀土元素分布型式呈REE近平坦型—LREE轻微富集型，微量元素原始地幔标准化的蛛网图和MORB标准化蛛网图上的分布型式总体很相似，富集大离子亲石元素Cs，Ba，Sr，Th，U而相对亏损Rb，K和高场强元素Nb，P，Zr， Sm，Ti和Y，显示同源岩浆演化成因特征。

It is proved in this paper that R/ is a principal ideal domain, where R=F+uF+…+u(superscript k-1)F, n is odd, and p is a prime number, and some necessary and sufficient conditions for the cyclic codes over R to be self-dual are given.

该文证明了R/是主理想环，其中R=F+uF+…+u(上标 k-1)F，n是奇数，p为素数，给出了环R上循环码是自对偶码的充要条件。

This paper describes the energy and mineral resources demand theory centered on capita mineral resources consumption and capita GDP S-shaped rules, mineral resources consumption intensity reverse U-shaped rules and progressive laws of wave rules for mineral resources demand, and the energy and mineral resources synthetic prediction model based on the demand theory.

中文摘要：本文介绍了以人均矿产资源消费与人均GDP"S"形规律、矿产资源消费强度变化倒"U"形规律和矿产资源需求波次递进规律等为核心的能源和矿产资源需求理论，以及以此为基础建立的能源与矿产资源需求综合预测模型；系统预测了2010-2030年全球及中国一次能源、粗钢、铜、铝需求趋势，并与其他预测方法和预测结果进行了对比，论证了这一理论模型的先进性和预测结果的可靠性。

In U-bend immersion tests under high temperature and high pressure, the number of cracks on the specimen in 80℃ is more than that in 300℃ due to the compactness and consequent protectiveness of the corrosion product layer.

高温高压U-Bend浸泡试验则发现80℃比300℃破损程度更为严重，原因为腐蚀层的保护性和致密度不同所致。

The report divided Hawaii County into four regions: North Hawaii in the northwest, Hilo area in the northeast, Puna and Ka'u in the southeast, and Kona in the southwest part of the island.

分为西北，希洛区夏威夷县划分为四个区域：北部，东北夏威夷，普纳和东南Ka'u的报告，以及柯纳在该岛西南。

Two anodes are connected in parallel and in push-pull with the other two via U sections.

二个阳极被连接在平行的和在推挽式的中用另外二经由 U 区段。

The low Th and U content of the copper ores suggests that the Pb isotopic compositions of this type of ores are normal lead instead of radiogenic lead.

而且，铜矿石的低U、Th含量为该类铜矿石的铅是正常铅提供了合理的解释。

Being very important, radiogenic components of helium (3He from 3H, 4He from U/Th)have been extensively used for groundwater dating.

中文摘要：放射性衰变产生的氦组分（3H衰变质产生3He，U/Th衰变产生4He）广泛地用水地下水测年。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
