海底这个充满神秘色彩的美丽世界,流传着许多动人的传说。海底龙宫几乎是家喻户晓,除了龙王和虾兵蟹将以外,孙大圣也要念着避水诀才能下去。诗中说“上九天揽月,下五洋捉鳖”。上九天揽月早已做到,现在还能飞得更远,可是下五洋遨游,困难还是不小。因为在太空的问题主要是真空和失重,而进入海底除了空气供应外,还有压力问题。每增加10米深度就要增加一个大气压,到1万米的海沟中就要经受1000个大气压的考验,人如果不加上耐压的保护壳,无论如何也经受不了这种压力。

Sea Dragon Palace is almost a household name, in addition to the Dragon King and shrimp soldier crabs, Sun Dasheng also want to avoid water tactics to go on.

Because the problems in space are mainly vacuum and weightlessness, there is pressure on the seabed besides the air supply. Each additional 10 meters depth will increase one atmospheric pressure, to 1 million meters in the trench to withstand 1000 atmospheres test, people without pressure casing, in any case can not stand the pressure.
