Pressure

壓強是標量，數值為受力的大小除以面積。
P=F/A

壓強是一個被廣泛使用的概念，
不同的介質中有不同的數學公式。

例如理想氣體的壓強
P=(2/3)ne, n是數量密度；e是分子平均平動動能。

In fact,
Pressure should be understood as Pressure.
As if a line should be understood as a line.
A point should be understood as a point

Pressure is intuitive, you can "feel" about what is pressure

Pressire (壓力) is simply the force that acts normally per unit area.
