| 释义 | MOS (Mean Opinion Score) form of dots (short marks known as dits to radio operators) and dashes (long marks, or dahs), with spaces between them, to represent letters, numbers, punctuation marks, and procedural signals (prosigns). The length of the spaces varies, with a short space between dots and dashes within a character, a longer space between characters, an even longer space between words, and a yet longer space between sentences. In order to speed transmission, the fewest number of dots and dashes represent commonly used letters (e.g., E is •,T is —, A is • —). Commonly used words are abbreviated (e.g., Calling is abbreviated CG, or — • — • — — •, as are commonly used phrases (e.g., Love and Kisses is abbreviated 88, or — — — • • — — — • •.Table M-1 provides the International Morse Code for English letters, numbers, and select punctuation marks and prosigns. |
