水深测量

The paper describes basic working principles of SDH-5 type water-depth measurement instrument. Aiming at the time disagreement between water-depth data and position data,the big error in the reading of water-depth measurment data, low automation,large amount of work in homework data processing, etc.

本文描述了SDH－5型测深仪的基本工作原理，并针对国产SDH系列模拟式水深测量仪器存在水深数据与定位数据记录时间不一致、水深测量数据判读误差大、自动化程度低、内业数据处理工作量大等缺陷，介绍了作者应用单片机技术研制的SDH－5／CLZ－Ⅰ型水深数据采集、处理与串行发送装置。

Today, enough soundings are available to enable a relief map to be drawn and we know something of the great variety of the sea bed's topography.

现在已有足够的水深测量数据来绘制一张大西洋洋底地形图，而且我们对海地地形的千变万化也有了一定的了解。

Today enough soundings are available to enable a relief map of the Atlantic to be drawn and we know something of the great variety of the sea-bed's topography.

现在已有足够的水深测量数据来绘制一张大西洋洋底地形图，而且我们对海底地形的千变万化也有了一定的了解。

Multi-beam Bathymetric System, which integrating new and high technology, is the most advanced bathymetric technique in the world right now.

多波束测深系统是当代高新技术的集成，是世界上目前进行水深测量最先进的手段，其特点在于用它可以对海底地形进行全覆盖无遗漏的测量，精度高、效率快。

There is a sharp contrast between photogrammertry and bathymetric survey in the operation efficiency, so it is difficult to acquire cartography data information in the same time.

由于摄影测量和水深测量的技术不同，作业效率相差很大，难以同时获取同一时间的制图数据信息。

The surface subsidence in the Yellow River delta foreland area brings changes to the land surface height there, and the depth datum in the bathymetric survey is determined on the basis of the level of land bench mark, so the changes in the level of land bench mark will affect the determination of depth datum and the accuracy of bathymetric survey.

国家海洋局，第一海洋研究所，山东青岛 266061文章摘要：黄河三角洲前沿的陆地由于受地面沉降的影响，使地面高程不断发生变化。在水深测量中，深度基准面是根据陆地水准点高程确定的，陆地水准点高程的变化影响深度基准面的确定，从而影响水深测量的准确性。

The surface subsidence in the Yellow River delta foreland area brings changes to the land surface height there,and the depth datum in the bathymetric survey is determined on the basis of the level of land bench mark,so the changes in the level of land bench mark will affect the determination of depth datum and the accuracy of bathymetric survey.

又由于黄河海港附近有一无潮点，其附近的潮汐性质变化大，在黄河三角洲前沿大范围水深测量中，根据测区潮位变化设立足够的验潮站及统一各个验潮站的水尺零点到同一个深度基准面上，是保证水深测量结果可靠的关键。

RS has some characteristics such as speediness, synchronization, large area, high resolution and so on, it can solve many problems which are hard to overcome in traditional fathoming method.

遥感以其快速、同步、大面积及高分辨率等特点，应用在水深测量中可以解决和弥补传统方法中存在的许多难以克服的困难，给浅海水深的测量带来了极大的方便。

Coastal map is a thematic map which record and describe spatial geography information and correlation of the narrow and long land terrain features of coast belt and marine element of shallow sea, surveying and maping by photogrammertry technique above instantaneous water line, marine elements information are required by detecting of bottom characteristics and bathymetric survey technique below nstantaneous water line.

海岸带图是记录和描述海岸地带狭长陆地地形要素和浅海海部要素空间地理信息及其相互关系的专题地图。瞬时水位线以上采用摄影测量方法测绘，瞬时水位线以下采取水深测量和底质探测方法获取海部要素信息。

This paper will systematically expatiate the interrelation and interaction between the factors of sound velocity, instrument correction and index etc.

结合黄骅港水深测量数据，针对声速剖面测量与声速改正以及声速、器差、指标差等要素间的内在联系及相互影响予以系统阐述。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
