This does not change the craft 's mass but decreases its volume , which lowers its buoyancy and makes it slowly sink .
这并不改变航行器的质量,但是减小了它的体积,这将降低它的浮力并使它慢慢下沉。
They 've installed new buoyancy foam , better camera systems , and an entirely new titanium sphere with more room and larger windows .
他们给它安装了新的浮力泡沫、更先进的摄像系统、以及一套全新的圆形钛舱,具有更大的空间和舷窗。
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 .
由于乙烷和空气的密度大体相当,燃料的重量没有什么多大的影响,进一步减少氮气的重量需要去产生浮力。
Aristotle tells us that thales thought the earth had a buoyancy much like wood , and that the earth floated on water much like a log or a ship .
