The strength deck,botom,and side shell of a ship act as a box girder in resisting bending and other loads imposed on the structure .the weather deck, bottom ,and side shell also form a fight envelope to withstand the sea locally, and to provide the buoyancy which keeps the ship afloat.

船舶在抵抗弯曲和其他强加在结构上的负荷时，强力甲板、船底和船侧构成一根箱形梁。露天甲板、船底和船侧也构成一个框架局部承受海水压力，并且提供使船舶浮在水面的浮力。

The Orion was a ship that had been ailing for a long time; in the course of its previous cruises thick layers of barnacles had collected on its keel to such a degree as to deprive it of half its speed; it had gone into the dry dock the year before this, in order to have the barnacles scraped off, then it had put to sea again; but this cleaning had affected the bolts of the keel: in the neighborhood of the Balearic Isles the sides had been strained and had opened; and, as the plating in those days was not of sheet iron, the vessel had sprung a leak.

俄里翁号是一条早已有了毛病的船。在它已往的历次航行中，船底上已结聚了层层的介壳，以致它航行的速度降低了一半，去年又曾把它拖出水面，剔除介壳，随后又下海了。但是那次的剔除工作损伤了船底的螺栓。它走到巴利阿里群岛时，船身不得劲，开了裂，由于当时的舱座还没有用铁皮铺底，那条船便进了些水。

Followingly, the rockingperformance is studied and based on the simulation, gaining the damage deformation picture of every part of bottom structures, and the changing circumstance of maximum stress and strain. Following this, the essay discusses the influence of collision capability that impacted by the rocks which have different shapes, dimensions and different collision places, obtaining the general conclusion of loads and deformation of the bottom structures based on the results of non-linear finite element program.

并以此为基础对触礁船船底结构触礁性能进行了研究，得到了触礁船船底各部分构件的损伤变形图，构件最大应力应变值的变化情况；讨论了不同的礁石形状及大小以及不同的触礁位置对触礁船船底结构碰撞性能的影响，以非线性有限元程序的计算结果为基础，取得了船底结构触礁时各构件的受力及变形分析的一般性结论。

Fortunately, Eta Carinae is far away, at least 7,500 light-years from Earth.

由于船底座伊塔星的质量是太阳质量的150倍，并且距离地球只有7500光年，因此当船底座伊塔星爆炸的时候，人类可从地球上看到一次壮观的&焰火&，或许在亮度方面足以和月亮媲美。

In fact, the Carina Nebula is one of our galaxy's largest star-forming regions and home to young, extremely massive stars, including the still enigmatic variable Eta Carinae , a star with well over 100 times the mass of the Sun.

事实上，船底座星云也是银河系最大恒星诞生区域的一部分，也是年轻、极大质量恒星的家园，其中含有仍处于神秘变换中的船底座η星，其质量是太阳质量的100多倍。

Eta Carinae is a star system located in Carina, about 7,500 light years away from the sun to 8,000 light years.

船底座伊塔星是位于船底座的恒星系统，距离太阳大约7500光年到8000光年。

On bottom slamming load and strength requirement for Structures of Box Barges;2. In this paper, two finite element models of plated grillages are built to calculate the transient dynamic response to slamming load of a high-speed ship.

本文运用大型有限元程序ANSYS建立某一高速船密加筋和纵骨架式两种形式的船底板架的有限元模型，计算这两种船底结构板架在砰击载荷作用下的瞬态动力响应特征，进行比较分析，得出能更好的抗砰击的高速船船底结构形式，为高速船的结构没计提供参考。

Covering an area surrounding the dusty Keyhole Nebula (NGC 3324) near picture center, the image spans about 40 light-years within the larger Carina Nebula at an estimated distance of 7,500 light-years, Like the more northerly Orion Nebula, the bright Carina Nebula is easily visible to the naked-eye.

船底座星云的推算距离为是7，500光年，所以这幅影像呈现了船底座星云约四十光年的区域。

D simulation research on the air cushion effect on the slamming pressure peak value of trimaran cross structure;2. A forecast method of slamming pressure acting on the ship outside plates;3. Not only can the fluid generate big slamming pressure s on the structure,but the structure s response has significant effects on the fluid s flow fields,as strong fluid-solid coupling exists between them.

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
