北极星

These are people who time the instants when stars are occulted by skyscraper walls and determine the rate of precession of the Earth's axis.

许多《天空和望远镜》的读者可以在计算机屏幕上跟踪公元前3000年冥王星的运动轨迹，但却无法在户外的光污染中找到北极星。

Noah strummed once, adjusted the tension on two strings, then strummed again, soft, quiet

习惯地，他往上看去，看到了猎户星座、北斗七星和北极星在秋季天穹下熠熠发光。

Serving as a guide,as a pole star or a pole of the earth.

In the nature of single blessedness he would one day take unto himself a wife when Miss Right came on the scene but in the interim ladies' society was a conditio sine qua non though he had the gravest possible doubts, not that he wanted in the smallest to pump Stephen about Miss Ferguson (who was very possibly the particular lodestar who brought him down to Irishtown so early in the morning), as to whether he would find much satisfaction basking in the boy and girl courtship idea and the company of smirking misses without a penny to their names bi or triweekly with the orthodox preliminary canter of complimentplaying and walking out leading up to fond lovers' ways and flowers and chocs.

这位幸运的单身汉有朝一日遇上相般配的小姐，就会娶她作妻子。到那时为止，与女人交往倒也是个不可或缺的条件。他丝毫不想为弗格森小姐（促使他凌晨来到爱尔兰区的，极可能就是这位特定的&北极星&哩）的事盘问斯蒂芬什么。尽管他十分怀疑斯蒂芬能够从诸如此类的事中得到由衷的满足：沉湎于少男少女式的谈情说爱啦，同只会嘻嘻嘻地傻笑、身上一文不名的小姐每周幽会上两三次啦，照老一套的程序相互恭维，外出散步，又是鲜花又是巧克力地走上亲密的情侣之路。

Other Northstar firsts on the XLR include four-cam continuously variable valve timing; electronically controlled, hydraulically actuated intake and exhaust cam phasers on all four camshafts for extra control; electronic throttle control; low restriction intake and exhaust manifolds and cylinder head ports; close coupled catalytic converters mounted directly adjacent to the exhaust manifolds; and a new air induction system, redesigned for enhanced capacity and noise attenuation.

Other北极星上首创的XLR包括四凸轮连续可变气门正时，电子控制，液压驱动进排气上的额外控制所有四个凸轮轴凸轮相位调节；电子节气门控制；低，限制进气和排气管和缸盖港口；紧密耦合催化转化器直接安装毗邻的排气管，以及一个新的空气感应系统，增强能力和噪声衰减重新设计。

It is the star to every wandering bark,Whose worth's unknown, although his highth be taken.

爱是北极星，指引着漂泊的船，高—不可测，价—不可算。

The points where the line cuts through the earth's surface are called the "rotation poles"; the visualised extention of the north axis line in space currently points to the star Polaris, the North Star.

该轴引出地球，在它周围它是以任何点及时真正地旋转。与地球表面相交的点就是称做&旋转极&；北极轴线在空间可见区域目前指向恒星北极星。

Meanwhile, the Russian navy has in recent days been engaged in what it has presented as a dramatic anti-piracy mission: apprehending, off the Cape Verde islands, eight people on board a Russian-owned cargo ship called the Arctic Sea, whose crew claimed to have been hijacked, at least briefly, in the Baltic in late July.

同时，俄罗斯最近宣称，他们进行了一次漂亮的海盗打击行动：在佛得角群岛，一艘叫作北极星的俄罗斯货轮上，共有8名海盗被捕。船员称，7月底他们突然被绑架。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
