在太空看地球是蓝色的,因为其中百分之七十是海洋。海洋对我们来说,是一个巨大而奇妙的宝库。在这个宝库中许多东西都是人类所需要的宝物。水母几乎全部由水构成,它身体中的水分实际上占到了百分之九十八,组成它身体的分子之间,有着大量的液体,经过提炼就能从中获得日常用的聚合胶。在材料科学家的眼里,大海中还有许多生物新材料。比如海参通常是柔软而富有弹性的,但是当它受到威胁时,它能够使自己的身体变硬,是什 Earth is blue in space because 70% of the ocean is sea. The ocean is a tremendous and wonderful treasure for us. Many things in this treasure house are treasures needed by mankind. The jellyfish, which consists almost entirely of water, actually contains 98% of the water in the body and contains a large amount of liquid between the molecules that make up its body, from which it can be derived from the usual polymeric gums. In the eyes of material scientists, there are many new biological materials in the sea. For example, sea cucumber is usually soft and elastic, but when it is threatened it hardens itself
