大气压力和已经被发现的深海里的低温环境应该会保持CO2有负浮力，也就是它会在水里下沉而不是上浮。
The atmospheric pressure and low temperatures found in the deep ocean environment should keep the liquid CO2 negatively buoyant , meaning it will sink rather than float.
当浮力把空气向上推，而重力又把它向下拉的时候，就会形成大气的重力波。
Atmospheric gravity waves form when buoyancy pushes air up, and gravity pulls it back down.
气球：一种大型气密球囊，内充热空气或轻于空气的气体（如氦或氢），以产生浮力，可在大气中上升和飘浮。
Balloon: Large airtight bag filled with hot air or a lighter-than-air gas such as helium or hydrogen that can rise and float in the atmosphere.
