惠更斯原理可以視為空間的各向同性的後果。「空間的各向同性」指的是，在空間裡，對於所有方向，物理性質都一樣。在各向同性空間（或各向同性介質）裏足夠微小的區域內產生的任何波擾，必會從那區域以徑向傳播。由這波擾產生的波動，又會在其它區域形成波擾，如此這般繼續不斷。所有波動的疊加形成了觀察到的波動傳播圖樣。

What is the time-invariant Schroedinger wave equation, and how does it apply to quantum mechanics?

Best Answer - Chosen by Asker

The three-dimensional time-independent Schrodinger wave equation is:

2M(U - E)ψ/ = ψ/x + ψ/y + ψ/z

where M is mass, U is potential energy, E is total, is planck's reduced constant, and ψ=ψ(x,y,z)

This equation is really the foundation of quantum mechanics, in that it describes the wave functions of particles, and helped physicists to better understand the quantization of energy levels in an atom.

"where M is mass"

M here is non-sr,非相对论M (basically no evil 輻射 or sr type of 輻射) , so "time" is not an real dimension or variable for us to worry about, and that is why 标量波动方程,时间, t, basically can be 从方程中消掉
