海洋是一个宝库,它里面蕴藏着富饶的工业原料。在海水中,存在有:食盐、氯化钾、硫酸钠、镁、铝、铁、铜、锶、银、金和溴。海洋占去了地球面积的三分之二以上,它里面蕴藏的工业原料虽然多,可是含量很稀薄,这样,就造成了在提炼的困难。历史上有好多的人,幻想从海里取金,并且用“电解”的方法做过尝试,毕竟还没有人能从海水中提炼出成吨的金子来。我们应该理解,现代科学距完全征服大自然并最高地利用它的财富这一个要求,还有很长一段途程。我们还应该相信,科学上是在前进着,特别是在我们优越的社会主义制度之下,它会跃进的更快,创造出更多奇迹,也许在不久之后,像从海里取金这样的幻想,是会变成为现实的。
The ocean is a treasure house with rich industrial raw materials. In seawater, there are: table salt, potassium chloride, sodium sulfate, magnesium, aluminum, iron, copper, barium, silver, gold and bromine. The ocean accounts for more than two-thirds of the Earth’s area. Although it contains many industrial raw materials, its content is very thin. This has caused difficulty in refining. There are many people in history who dreamed of taking gold from the sea and tried it with the “electrolysis” method. After all, no one has been able to extract tons of gold from the sea. We should understand that there is still a long way to go for modern science to meet the requirement of completely conquering nature and making maximum use of its wealth. We should also believe that science is advancing. Especially under our superior socialist system, it will leap forward faster and create more miracles. Perhaps in the near future, it will be like the illusion of taking money from the sea. It will become a reality.
