Common mistakes
The force on unit area is called pressure.The force per unit area is called pressure.
介词错误：表示“每单位面积”时，英语使用“per”，而中文直译“在单位面积上的力”可能导致误用“on”。应使用介词“per”表示比率关系。
Force per a unit area is an important concept.Force per unit area is an important concept.
冠词误加：在“per unit area”这个固定短语中，“unit area”前不加冠词，因为“per”已表达“每一”的含义。添加“a”是多余且不正确的。
