For example, a single electron in an unexcited atom is pictured classically as a particle moving in a circular trajectory around the atomic nucleus, whereas in quantum mechanics it is described by a static, spherically symmetric wavefunction surrounding t

例如，单个电子在不活跃原子里被经典描述为粒子围绕原子核圆形运动，但是在量子力学里它通过用静止、围绕核子的球对称波函数来描述。
