So if we want to talk about the volume of that, we just talk about the surface area, which is 4 pi r squared, and we multiply that by the thickness d r.───如果我们要讨论它的体积,我们要用的是表面面积,也就是4πr的平方,乘以厚度dr
perfectly spherical shell dr at some distance, thickness, d r, dr we talk about it as 4 pi r squared d r, so we just multiply that by the probability density.───在某个地方的完美球型壳层,厚度,我们把它叫做4πr平方,我们仅仅是把它,乘以概率密度。
