Locality of action shows itself in the finite speed of light, in the inverse square law of fields, and in macroscopic statistical effects, such as rates of reaction and the speed of sound.
作用力的局限性体现在光速是有限的，体现在场的平方反比定律之中［4］，还体现在宏观统计效应上，如反应速度和音速等。
The law of action and reaction is universal.
作用和反作用的定律是通用的。
The law of action and reaction is not exclusively for physics.
动作和反应的定律并不专限于物理的范畴内。
