常用于物理学、工程学或日常描述物体漂浮或沉没的现象。

Commonly used in physics, engineering, or daily descriptions of objects floating or sinking.

1 木块在水中的浮力使其能够浮在水面上。（The buoyancy of the wood block in water allows it to float on the surface.）
2 潜水艇通过调节自身的浮力来控制上浮和下潜。（Submarines control their ascent and descent by adjusting their buoyancy.）
3 浮力的大小取决于物体排开液体的体积。（The magnitude of buoyancy depends on the volume of fluid displaced by the object.）
4 在死海中，由于盐分高，浮力很大，人可以轻易漂浮。（In the Dead Sea, due to high salinity, the buoyancy is great, allowing people to float easily.）
5 工程师在设计船舶时必须考虑浮力原理。（Engineers must consider the principle of buoyancy when designing ships.）
