在航行中

The Periscope Drawtube will be bent because of the water resistance in sailing and this bend will cause the error of star measurement. Due to its especial structure, contactless measurement is the only way to measure its bend degree. First this paper introduces the method by linear array CCD based on structure and light path; Second it expatiates linear array CCD work principle and driving scheduling with example of TCD1501C and the driving circuit by CPLD. The output signal of linear array CCD includes common disturbance so the differential amplifier is needed. In order to make the signal adapt to computer processing, a threshold circuit with Schmitt characteristic and the data process following threshold are given. At last, some key problems in application are given.

潜艇潜望镜的镜筒在航行时受到水的阻力会产生弯曲变形，这种变形会造成潜艇对星体测量的误差；由于镜筒结构的特殊性，对其弯曲程度的测量只能采用非接触方法；首先从结构和光路方面介绍采用线阵CCD作为检测元件实现对镜筒弯曲程度的测量；其次以东芝公司的线阵CCD（TCD1501C）为例阐述了其工作原理及驱动时序的控制要点，并介绍了基于可编程逻辑器件的线阵CCD的驱动电路；线阵CCD输出的信号中含有共模干扰，必须采用差分放大器将其抑制；为将信号转化为适合计算机处理的数字信号，文中给出了有一定实用价值具有施密特特性的二值化处理电路及二值化后的数据处理过程；最后阐述了在实际使用中的一些关键问题。

But ships often encounter waves in sailings. For satisfied stability of ship, designers often hold some overmeasure.

但是，船舶在航行时经常会在波浪中航行，为了满足稳性要求，设计者在考虑稳性时会保留一定的余度。

Ship always select rhumb line when the voyage is short while great circle line is the shortest route , so it is always used during the oceangoing voyage for the purpose of voiding the terrible environments in the high latitude sections , sometimes we have to turn to composite navigation line .

等角航线是最简单，短程航行中最常用的航行方式；而大圆航线是跨洋长距离航行时经常采用的，地理航程最短的航线；在大圆航行的过程中，有时为了避开高纬度地区的恶劣环境，我们还要选择混合航线。

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。

If,during its voyage, a case of a quarantinable disease or a suspected quarantinable disease is discovered

受入境检疫的船舶，在航行中，发现检疫传染病、疑似检疫传染病

If,during its voyage, a case of a quarantinable disease or a suspect ed quarantinable disease is discovered

受入境检疫的船舶，在航行中，发现检疫传染病、疑似检疫传染病

Throw off the bowlines. Sail away from the safe harbour. Catch the trade winds in your sails. Explore. Dream. Discover.

您应扔掉帆索，将船驶离避风港，并在航行中抓住信风，尽情探索、梦想、发现。

Concept of double-inlet water-jet system is designed with one inlet in side and the other in bottom.

配合本文提出的带有侧进水口及底进水口的双进水口喷水推进系统的概念设计，该高速艇可在深水中高速航行、在浅水中安全航行，有效最小水深可和该艇的静态吃水相当。

During the journey, their boat began to sink.

在航行中，他们的船要沉了。

Weapons only in sailing boats can be used when there is a real threat.

武器只有在航行中船只有真正威胁时才能使用。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
