2014年4月3日,三亚市的《南岛晚报》报道了4月1日四名工人在三亚湾海坡南门海域游泳,3人溺亡,一人生还的消息。溺亡男子是退潮时游进大海两三百米远,海水是回抽时,应该是力气耗尽游不回来,当地有经验的水手也不敢游那么远。看了这篇报道很悲痛,我想有关技术人员能否研制一把防水的溺水求救信号枪,可以用色彩和光线的语言(有声音就更好)发出求救信号,游泳的人象带漂流袋
On April 3, 2014, the Nan’ao Evening News in Sanya reported on April 1 that four workers were swimming in the south gate of the Slope of Sanya Bay Haipo and three people were drowned and one survived. Drowning men are two or three hundred meters into the sea at low tide, when the seawater is pumping back, it should be exhausted, swim not come back, the local experienced sailors did not dare swim so far. I was saddened to read this article. I wonder if the technical staff could develop a waterproof drowning distress signal gun that could send a distress signal in color and light (better sound) and a swimmer like a rafting bag
