國(guó)際摩斯密碼代號(hào)，因其識(shí)別性強(qiáng)易發(fā)送而被選用，其代號(hào)為（? ? ? — — — ? ? ?）。 同時(shí)，俗詞源解讀為“save our ship or save our souls”，某種程度上加強(qiáng)了該信號(hào)的流傳度。
英文詞源
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.
