浮力 - 维基百科，自由的百科全书
- 在静止流体中，浮力有以下四种常见求法。 1. 定义法：F {\displaystyle F} 浮= F {\displaystyle =F} 下表− F {\displaystyle -F} 上表 1. 由于浮力是各表面受流体压力的合力，左右两侧的压力由于深度相同而抵消，剩余上下两侧的压力差即为浮力。 1. 称重法：F {\displaystyle F} 浮= G − F {\displaystyle =G-F} 1. G {\displaystyle G} 为物体重力，F {\displaystyle F} 为物体完全浸没时弹 …

Buoyancy | History, Science, & Applications | Britannica
Buoyancy is the tendency of an object to float or rise in a fluid due to the force of gravity and fluid pressure. Learn how buoyancy works, how it relates to density and Archimedes' principle, and how it is used in ships, submarines, and fish.

浮力（英語： Buoyancy ）指物體浸入液體後，與所受重力相反的豎直向上的力。 在柱形流體中， 壓力 隨著 深度 增加而增大，因此柱形流體底部的壓力大於上部的壓力。
Buoyancy aid - Wikipedia
Buoyancy aids are a specialist form of personal flotation device (PFD) used most commonly by kayakers, canoeists, people practicing rafting, and dinghy sailors. They are designed as a flotation aid, rather than merely a life-saving device and have several key differences to other PFD's and lifejackets. Some buoyancy aids may not provide the same high level of protection as lifejackets.

Buoyancy - Nexus Wiki - AAPT
To control buoyancy, aquatic organisms usually adjust the volume of their internal air chamber. Increasing the volume occupied by air will decrease their average density, giving them a lower density than water and allowing them to rise.
