浮力的
flotative
- 这种大西洋的海草有点像英国沿海生长的岩藻，含有很多有浮力的膜泡。
Like the fucus, which grows on British shores, this Atlantic vegetation contained buoyancy bubbles. - 若菲尔认为明智的做法是在佛罗里达州布置水栅——这种有浮力的管子可以将石油隔离在海湾内，远离敏感的海岸。
Roffer thinks it would be wise for people in Florida to lay out booms—long, buoyant tubes that can encircle sensitive areas to keep oil at bay. - 这里的因果好像有点问题。由于乙烷没影响，燃料的重量又可以忽略不计，所以用来产生浮力的氦气的需求量减少了。
And since ethane has roughly the same density as air, the fuel in effect weighs nothing, further reducing the amount of helium needed to create buoyancy.
