SOS的词源

英文词源

SOS

1910, from International Morse code letters, chosen arbitrarily as being easy to transmit and difficult to mistake. Not an initialism (acronym) for "save our ship" or anything else. Won out over alternative suggestion C.Q.D., which is said to mean "come quickly, distress," or "CQ," general call for alerting other ships that a message follows, and "D" for danger. SOS is the telegraphic distress signal only; the oral equivalent is mayday.

SOS：求救信号

国际摩斯密码代号，因其识别性强易发送而被选用，其代号为（• • • — — — • • •）。 同时，俗词源解读为“save our ship or save our souls”，某种程度上加强了该信号的流传度。
