What do these three letters stand for?
The international morse code distress signal, S.O.S., is another "word" with a false acronymic origin. S.O.S. does not stand for Save Our Souls, Save Our Ship, Stop Other Signals, Sure Of Sinking, or any other phrase.
S.O.S. was chosen as the universal distress signal by the International Radio Telegraph Convention of July 1908 because this combination of letters, three dots followed by three dashes followed by three dots (...---...),was easy to send and easily recognized. The letters themselves are meaningless.
很多人都以为S.O.S.是由一些单字的首字母缩写而成,如Save Our Souls(拯救我们的生命!),Save Our Ship(拯救我们的船只!),Stop Other Signals(停止发送任何其他信号!),Sure Of Sinking(船就要沉了!)等。
其实,S.O.S.是国际莫尔斯电码救难信号,并非任何单字的缩写。鉴于当时海难事件频繁发生,往往由于不能及时发出求救信号和最快组织施救,结果造成很大的人员伤亡和财产损失,国际无线电报公约组织于1908年正式将它确定为国际通用海难求救信号。这三个字母组合没有任何实际意义,只是因为它的电码
...---...(三个圆点,三个破折号,然后再加三个圆点)在电报中是发报方最容易发出,接报方最容易辨识的电码。
