Visual signals can be sent by using flags or an Aldis lamp. An Aldis lamp is an electric lamp used for flashing messages in Morse code. The traditional method of signaling from one ship to another is by using flags. There are different colored flags for each letter of the alphabet. There are also pennant-shaped flags for numbers, and a long pennant, known as an answering or code pennant. Three other flags, which are burgee-shaped, are known as substitutes. These show that the flat or pennant is being repeated. Besides standing for a letter of the alphabet, each flag, when hoisted along, has another meaning. For example, the 'W' flag also means: 'I require medical assistance'. Flags can also be hoisted in combinations of two, three or four. Siren, whistle, bell or other sound signals can be used in fog and similar circumstances when visual signals can not be seen.(1)An Aldis lamp is used for ______.A.sending flag signalsB.sending sound signalsC.transmitting Morse codeD.flashing flags(2)Burgee-shaped flags are used as substitutes to show ______.A.'I requiring medical assistance'B.'repeating'C.'answering'D.'code' pennant(3)Communications over relatively short distances may be made by ______.A.Morse CodeB.Either visual or sound signalsC.sound signalsD.visual signals(4)______ are used in fog and similar circumstances when visual signals can not be seen.A.SubstitutesB.The ship's siren, whistle or bellC.Visual signalsD.Pennant-shaped flagsThe official original data (S57 data) of the electronic nautical chart is usually supplied on CD-ROM or,in case of updates, via digital telephone or satellite communication system. This original data is also called electronic nautical chart (ENC).The chat database is organized in cells that cover the entire earth's surface without overlapping. The cells store all nautical chat objects as well as objects created only during the operation of the system, such as waypoints and leg lines, notes, positions of own ship and of other vessels, etc.The data in the System Electronic Nautical Chart (SENC) is generated from the original data of the ENC. The Enc has to be kept unaltered in order to be able to reconstruct the SENC data if this is unintentionally damaged or destroyed. In SENC, the chart data is stored in a proprietary file format designed by the ECDIS manufacturer for speed and reliability.The S57 data represents a specific kind of attributed vector data. The kind of data (object description with geometry and geographical position) requires an efficient kind of storage. For compactness and speed, vector data is the optimal solution in contrast to the voluminous raster data.(1)Which of the following is correct statement?A.ENC is the raw data of the Electronic Nautical Charts and it may be changed by ECDIS manufacturerfor speed and reliabilityB.The database of an Electronic Nautical Chart System is compacter and the speed of the system is faster if those use voluminous dataC.ENC is a kind of voluminous raster data while the SENC is a kind of vector dataD.SENC is the raw data of the Electronic Nautical Charts and it may be changed by ECDIS manufacturer for speed and reliability(2)The passage implies ______.A.ENC is the raw data of the Electronic Nautical ChartB.The vector data is the optimal solution for ECDISC.SENC is the raw data of the Electronic Nautical ChartD.SENC may be designed with different representation purposes by different ECDIS manufacturers(3)Which of the following is Not Correct as to the ENC and SENC?A.The ENC can be reconstructed from the SENCB.The ENC is the raw data of the Electronic Nautical ChartC.The SENC is generated form the S-57D.The SENC can be reconstructed from the S-57①CD-ROM②Digital(4)The passage indicates that the update of the S-57 can be done via ______.telephone③Satellite communication system④Floppy DiskA.②③B.①～④C.②～④D.①～③【单选29】You are offloading garbage to another ship.
