Buoyancy
中文意思：浮力
音标：[ˈbɔɪənsi]
词性：名词
定义：
Buoyancy 是指物体由于液体或气体的作用而产生的浮力，使物体能够漂浮或上升。具体而言，当物体被部分或完全浸入液体（如水）或气体中时，液体或气体会对物体施加一个向上的力，这个力就是浮力，通常与物体排开的液体或气体的重量相等。
常见用法：
The buoyancy of an object determines whether it will float or sink.
浮力决定了物体是漂浮还是下沉。
用法：
Scientific Use: Buoyancy is a key principle in understanding why ships float.
Everyday Use: The buoyancy of the raft helped it stay afloat in the river.
Physics Context: Archimedes' principle is often used to explain buoyancy.
例句：
The boat stayed afloat due to the buoyancy of the water.
The scientist studied the buoyancy of different objects in saltwater.
Buoyancy is what allows icebergs to float on the ocean.
