Norsk Hydro ASA Monday said it will divest its automotive components operations as part of the company's strategy to reduce engagement in downstream aluminum, while investing in the repositioning of metal production operations.

周一，海德鲁称公司计划退出汽车组件运营而投资金属生产。此次行为是公司减少下游铝行业的发展战略。

There was conspicuous contradiction appeal between water supply and demand in the Yellow River basin in 1997 because of much less precipitation and runoff than nounal and no-flow in the lower reaches in 1997 was the most serious in the records.

1997年，由于黄河流域降雨、径流量较常年明显偏少，水资源供需矛盾十分突出，黄河下游出现了有资料记录以来断流最为严重的一年，利津站于2月7日开始断流，截止到12月31日，断流13次，共计226d，与有记录以来的历史资料比较，呈现出断流开始时间最早、恢复过流时间最晚、断流河段最长、断流次数最多、断流时间最长等特点。

This paper is studying on the isolation technique、purification、identification the molecule structure of the new agricultural antibiotics 2507 which can controlling oomycetes developed by Plant Protection Institute of Guangdong Academy of Agriculture Sciences.

本研究主要是围绕广东农科院植保所自行开发出的防治植物卵菌病害的新农用抗生素2507的提取工艺、分离纯化、结构鉴定的下游过程进行的，取得的主要成果是

Based on an analysis of field data, it is expounded that the overbank flood is of strong capacity in sediment deposition on the flood plain and scouring in the main channel under the condition of continuous shrinkage of channels on the lower Yellow River.

通过实测资料分析，阐明黄河下游宽河道在持续萎缩的情况下漫滩洪水仍具有较强的淤滩刷槽的行洪特点，指出漫滩洪水造成的滩地淤积主要来自于滩槽水流泥沙的横向交换。

By use of the observed data from Gaocun—Sunkou reaches on the down stream of the Yellow River analysed the overbank flood routing regularity and the impact of transitional reach are analysed.

利用黄河下游高村至孙口河段漫滩洪水观测资料，分析了过渡型河段漫滩洪水演进规律及其影响因素。

Channel shrinkage ; overbank flood ; bank-flush discharge ; sediment deposition on flood plain and scouring in main channel ; water and sediment diversion ; river channel above Taochengpu on lower Yellow River

河槽萎缩；漫滩洪水；平滩流量；淤滩刷槽；调水调沙；黄河下游陶城铺以上河道

Ratios of AN/and Flur/calculated suggested that PAHs in Qiantang River were mainly from petrogenic origin and the contribution of petrogenic PAHs was decreasing during the last two years.(2)The input and output of PAHs in estuary section of Qiantang River were 21.83 t/yr and 13.49 t/yr,respectively.The input of PAHs was higher than output of PAHs,which caused the increase of concentrations of PAHs in Qiantang River.

2钱塘江河口段15种PAHs的输入通量约为21.83 t/yr，其中干沉降输入约为0.41 t/yr，湿沉降输入约为0.78 t/yr，地面径流输入约为8.50 t/yr，上游输入约为12.14 t/yr，下游输出通量约为13.49 t/yr，输入输出通量之差为8.34t/yr，输入通量高于输出通量，导致水体中PAHs浓度逐年升高。

PhyA is the photoreceptor of far-red light perception in Arabidopsis and mediates the inhibition of the hypocotyl elongation under FR light. phyA has two domains : the N-terminal photosensory domain with a chromophore-binding site and the C-terminal domain which contains signaling motifs such as a kinase domain.

phyA为阿拉伯芥中远红光的接受体，在远红光中可抑制下胚轴延长，phyA的N端带有一个可感受光讯息的色基，C端含有可传递讯息给下游基因的kinase区域。

At the early stage of HIRBD, the Toll-like receptors may induce NF-kB activation, leading to the coordinated induction of multiple genes, which is involved in inflammatory, apoptosis and cell proliferation. Genes induced by NF-kB are responsible for the physiopathological process of early brain damage in neonatal rats with HIRBD.

在新生大鼠HIRBD早期阶段，主要通过Tlrs诱导NF-kB激活，从而调控下游炎性反应、细胞凋亡及细胞增殖相关基因的表达，参与HIRBD的病理生理过程。

So piperylene petroleum resin was applied preferably in downstream products,and the products yield was increased by improving post treatment process.

介绍了国内外间戊二烯石油树脂合成技术的改进进展，主要体现在催化体系的改进及聚合单体和溶剂的改变，通过引入官能团及共混等方法改善间戊二烯石油树脂的色度、耐候性和相容性等性能，从而使间戊二烯石油树脂在下游产品中得到更好地应用；通过后处理精制工艺的改进，可提高产品的收率。

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
