作者紧密结合西北地区环境恶化的现状，如植被破坏，土地退化、水资源缺乏和环境污染，及其对区域经济发展带来的损失等问题，进行了全面系统的分析，在追寻生态环境恶化成因的基础上，提出了积极的改良对策。

The chamber in the northwest angle, just beyond the last of the Siva temples, is of special interest to us; for here Sri Ramakrishna was to spend a considerable part of his life.

西北角落的房间，就像较远处的一座湿婆庙一样，特别地引起我们的兴趣；因为室利罗摩克里希纳一生中相当多的时光都在这里度过。

Based on seismic records using SIG sparker from a joint Sino French study on marine geology of the East China Sea in 1996,the distribution area of submarine paleodeltas of the Yangtze River(and/or the Yellow River)during the early and middle time of the late Pleistocene is determined.

中更新世晚期东海陆架为一自西南向东北倾斜的广阔的河流冲积平原，晚更新世以来自西北方向的大型河流的三角洲受此控制主要发育在东北部较低地区。

By optimizing the culture conditions, the present work developed for the first time an efficient system for inducing embryogenic callus formation and plant regeneration through somatic embryogenesis from both dune reed, an ecotype with drought tolerance growing in desert region of northwestern China and local swamp reed .

本研究通过优化培养条件首次建立了沙丘芦苇（一种生活在中国西北沙漠地区的具抗旱性能的芦苇生态型）和当地的沼泽芦苇的体外培养体系。

In Northwest Arid Region, along with the developing of social economy and the accelerating of citified process, scarce condition will be more stressed, has affected the development of social economy greatly.

本论文在借鉴国内外先进经验的基础上，结合张掖实例，探索研究了我国西北干旱区生态环境质量评价和水资源合理配置的途径和方法，以期使短缺的水资源能够得到最合理的配置和利用。

The morning of November 14, the 1st Battalion/7th Cavalry, approximately 450-men strong under Lieutenant Colonel Hal Moore, began operations in the Ia Drang Valley approximately 14 miles northwest of Plei Me in South Vietnam.

11月14日的早晨，第7骑兵团第1个营，近似450名强壮的士兵在Hal Moore中校带领下，从南越的Plei Me地区西北14英里的地方开始向Ia Drang山谷进发。

Different plant expression vectors had been respectively transferred into upland cotton cultivars Jinman12, Jinmian7, Xinluzao1 and Jihe321 via Agrobacterium tumfaciens transformation. These vectors carried cryIAc3 gene, which encodes Bacillus thuringiensis δ-endotoxin, under the control of chimeric OM promoter, CaMV 35S promoter, and cotton leaf curl virus RP promoter respectively; snowdrop lectin gene (Galanthus nivals agglutinin, gna) trans-regulated by rolC promoter controlled TGAla factor; and multivalent expression construct of both cryIAc3-cpti fusion gene and gna gene. A large number of transgenic plants and their progenies had been obtained.

为了提高外源基因的表达量，延缓害虫产生耐受性，本文通过将携带有分别在高效复合OM启动子，CaMV35S启动子及棉花曲叶病毒RP启动子控制下的苏云金杆菌杀虫毒蛋白基因cryIAc3；反式调节因子增强韧皮部表达的雪花莲外源凝集素(Galanthus nivals agglutinin，GNA)基因；以及同时含有cryIAc3、豇豆胰蛋白酶抑制剂基因和gna三价抗虫基因的植物表达载体，以根农杆菌介导法分别将这些表达载体导入了陆地棉新陆早1号、晋棉7号、晋棉12号和冀合321等我国西北棉花主要栽培品种，经体细胞胚再生获得了大批转基因再生植株。

But a piece of research just published in the Proceedings of the National Academy of Sciences by Paola Sapienza of Northwestern University, near Chicago, suggests an alternative—that it is not a person's sex, per se, that is the basis for discrimination, but the level of his or her testosterone.

但是靠近芝加哥的西北大学圣保罗分校最近在国家科学院的报告中发布的一些研究让人们对此看法有所改变——人们对一个人的性别并不是基于偏见，而是取决于他睾丸激素分泌的程度。

In order to prvoide the new clue for the later tapping oil potential of maturing oilfiled, especially for the stratagem adjustment of high water-cut inefficient exploitation reservoir, and prolongate the realm and orientation of tapping oil potential, the waterflooding characteristics and the law of remaining oil distribution were studied.

结果表明，该块油层水淹程度仅80%左右，剩余油在平面上分布于区块的绝大部分区域，且与构造高低无明显关系，纵向上主要集中于层段的上部，尤其是位于该块西北区构造低部位的北断层区潜力单元，是与目前老油田潜力区主要局限于正向型微构造区所不同的新类型与新领域。

Water is not only a renewably natural resource but also a key factor in the environment.

目前西北干旱地区的生产力随着水资源开发的强化而不断提高，但在开发利用过程中，也将或已经出现了水环境对人类的不利影响，所以正确处理水资源开发与人九的关系是

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。
