平方反比定律 Inverse-square law

（重定向自Inverse square）

反平方定律是一个物理学定律，又称平方反比定律、逆平方律、反平方律；如果任何一个物理定律中，某种物理量的分布或强度，会按照距离源的远近的平方反比而下降，那幺这个定律就可以称为是一个反平方定律。

Inverse-square law 平方反比定律

（重定向自Inverse square）
S represents the light source, while r represents the measured points. The lines represent the flux emanating from the source. The total number of flux lines depends on the strength of the source and is constant with increasing distance. A greater density of flux lines (lines per unit area) means a stronger field. The density of flux lines is inversely proportional to the square of the distance from the source because the surface area of a sphere increases with the square of the radius. Thus the strength of the field is inversely proportional to the square of the distance from the source.

In physics, an inverse-square law is any physical law stating that a specified physical quantity or intensity is inversely proportional to the square of the distance from the source of that physical quantity. The fundamental cause for this can be understood as geometric dilution corresponding to point-source radiation into three-dimensional space (see diagram). Mathematically formulated:
