其它东西，包括发动机，电子设备和用于浮力的轻型泡沫都置于舱外的机身上，以减轻重量。
Everything else, including the motors, electronics and the lightweight foam that buoys the vehicle, is housed outside the hulls in the fuselages, saving weight.
重量计算出丝支付，从水下浮力的货物。
Calculate weight of wire paid out, buoyancy from submerged cargo.
非浮冰(不服从阿基米德浮力定律的部分，未排开同重量的水)会转变为浮冰(服从阿基米德浮力定律)，从而海平面上升。
2 non-floating ice (which is not subject to Archimedes's principle that it displaces its own weight of water) would be converted into floating ice (which is), and the sea level would rise.
潜水后获得中性浮力，潜水者完全没重量。
After diving and attaining neutral buoyancy, a diver is weightless.
向上的浮力等于向下的重量。
总说明书、重量重心计算书、稳性计算书、结构计算书、干舷和储备浮力计算书、不沉性计算书等内容。
Statement of the total weight calculation of center of gravity, stability calculation, structure calculation, freeboard and reserve buoyancy calculation, the calculation of unsinkable books and so on.
部分浸没或全部浸没在流体中的物体所受到的向上浮力，等于它所排开流体的重量。
The upward buoyant force on an object partially or wholly submerged in a fluid is equal to the weight of the displaced fluid.
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.
浮力天平的测量是利用阿基米德定理，计算出配重物体受到的浮力，再通过杠杆平衡的原理得出配重物体浮力的变化即被测量物体的重量。
Based on Archimedes theorem and lever balance principle, we can calculate the buoyancy's variety of the balance objects. This variable just equals to the weight of the measured object.

Hence when they are respectively weighed in air, the buoyancy of the air will render the former heavier.
水的重量、浮具还有其它一些可用器材，都可用来增加水的阻力，除此之外，这些器材还要能为人体提供浮力及维持人体平衡。
Water weights, floating belts, and other useful equipment are used to increase water resistance as well as help with flotation and balance.
