| 单词 | wave function |
| 释义 | wave function A function ψ(x,y,z) appearing in Schrödinger's equation in quantum mechanics. The wave function is a mathematical expression involving the coordinates of a particle in space. If the Schrödinger equation can be solved for a particle in a given system (e.g. an electron in an atom) then, depending on the boundary conditions, the solution is a set of allowed wave functions (eigen functions ) of the particle, each corresponding to an allowed energy level (eigenvalue ). The physical significance of the wave function is that the square of its absolute value, |ψ|2 , at a point is proportional to the probability of finding the particle in a small element of volume, dxdydz, at that point. For an electron in an atom, this gives rise to the idea of atomic and molecular orbitals |
