多船体船的

A bailer or manual water pump is not required for any multi-hull vessel that has subdivided multiple-sealed hull construction.

水斗和水泵对于多船体或者多舱的船不是必须的！

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。

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。

On the basis of the presented hydroelastic theory, a computer code HEAF (Hydroelastic Analysis Program for Fast Sea Transportations) is developed to calculate wave loads and dynamic responses of mono-or multi-hull high speed vessels in the frequency and time domain.

在理论研究的基础上，本文作者开发了计算机应用程序HEAF(Hydroelastic Analysis Programfor Fast Sea Transportations)，通过与结构干模态分析程序的数据接口，能够进行线性频域和非线性时域单体或多体高速船舶水弹性分析，可用以计算单体或多体高速船在各种海况下的波浪载荷、船体刚体运动和结构的弹性动力响应。

The ship can accommodate 300 people, tourists, double-bodied hull, hull length of 30 meters, 11 meters wide, divided into upper and lower layer, the first layer of steel structure, with cabin, VIP hall, multi-function hall, a rest, recreation place; second layer aluminum structure, stainless steel railings, with platform, removable seats, where you can listen to sound of the sea, blowing sea breeze, view the unique scenery of the sea.

该游轮可容纳游客300人，双体式船体，船身长30米，宽11米，分为上下二层，第一层为钢结构，设有客舱、贵宾厅、多功能厅，是休息、娱乐的场所；第二层为铝合金结构，不锈钢栏杆，设有平台，可移动座位，您可以在此听海声、吹海风、观海上特有的风光。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
