船体

Since the hull is sealed air pressure inside the hull increases as ballast water is taken aboard.

由于船体是密封的空气压力，内船体增加的压舱水是采取在船上。

Finite cylindrical shells are the main structures of the pressure and non-pressure hull of submarine.

有限长圆柱壳是潜艇耐压和非耐压船体的主要结构形式，在潜艇船体上敷设阻尼层是一种主要的减振降噪方式。

As long as obtain S-N curve, the actual load history and the cumulative damage rule of the submarine pressure hall, the estimate of the fatigue life with pressure hull become possible.

只要取得船体构件材料之S-N曲线、船体构件之实际负荷履历以及疲劳累积损坏率这三方面的评估资料，即可对压力壳的疲劳寿命进行合理预估。

Don't worry, although the ship is not upright now, we can manage to make it all right before completion of loading this hold.

请不要担心，虽然现在船体有点偏，但这个舱完货前，我会保持船体平衡。

A second later, a gaping hole appeared in the Seadog's hull, three levels high and wide, guzzling saltwater.

一分钟之后，"海豹号"的船体出现了一个很深的破洞，足有三英尺见方，海水正大量地涌入船体。

It not only makes sure for the ship safety, but also reduces the ship rotation in the time from the ship aft floating to whole ship folating during the ship launch, as well as preventing the ship"" impact with the slipway.

本文主要是提出合适的下水方案，既要保证船舶下水常规安全，又要尽量减小下水过程中从尾浮至全浮阶段船体的偏转，避免船体与船台相碰撞事故。

This article is devoted to the development hull lines fairing, analyses some cases of this topic in home and abroad, poses some technical questions of hull lines fairing and also gives the solution including the spline curve precision fairing theory, ship data series, adept more data interactive way, and the integration of lines fairing and CAD/CAM, etc.

文摘：本文以船体线型光顺的发展方向为题，论述了国内外的发展概况，针对国内情况提出了船体线型光顺的一些技术问题和解决方案，包括建立样条曲线的精密光顺理论，系列船数据库，更多地采用数据图形交互手段，线型光顺和CAD/CAM实现一体化。

Secondly, the dissertation establishes mechanics model of the robot in stationary and moving state and analyses the robot movement.

论文建立了船体表面水下清刷机器人在船体表面处于静止和运动状态下的力学模型，进行了相关的力学分析。

The blockade runners were armed with turreted guns positioned on each side of the ship's bow and point-defense guns lining the main superstructure.

进军级封锁穿越者护卫舰的炮塔安置在船体两侧，点防御火炮则被安装在主船体的上层建筑里。

Thirdly, a welding platform scheme for huge circumferential seam's sealing is proposed, which is composed of multiple 3 DOF robots. It can control the pose adjusting during the rotation of the ship module. As to the different part of the ship hull, the inverse kinematics arithmetic of cylindraceous, elliptical and conical ship modules are given respectively.

第三，在船体环缝焊接系统中，本文提出了一种由多个3自由度滚轮机器人组成的环缝焊接平台的控制方法，实现了船体模块在旋转焊接时的姿态调整，并分别针对船艏、船舯和船艉的不同形状给出了相应的逆运动学算法以及可用于实时操作的简化控制算法。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
