航海英语阅读理解题集 Unit 01 Passage 1 Admiralty TotalTide Admiralty TotalTide (DP550) is a PC-based （基于个人电脑）tidal prediction program （预测程序）which uses the same prediction algorithms （运算法则）and Harmonic Constants （谐和常数）as the Admiralty TotalTide, and has been designed to meet SOLAS carriage requirements（运输条款）. Tidal heights for both Standard and Secondary Ports are displayed in graphical and tabular form以图表形式. Tidal Stream rates 潮流速率are presented on a chart-based diagram表示在一张航用海图上的简图. TotalTide permits the mariner to select and simultaneously 有选择地或同步calculate tidal heights for multiple ports 多个港口for up to seven days最多达到7天. Output from the system 从该系统输出的形式also includes periods of daylight 白昼and nautical twilight航海的黄昏、黎明, moon phases and a springs and neaps （大、小潮）indicator. Underkeel and overhead clearance 富裕水深和高处间隙can be displayed in a graphic form 以图表形式to aid passage planning帮助航路设计.
