研究了一维三角形势阱中粒子在单色光扰动下的量子动力学。虽然经典动力学由标准映射描述，但量子运动并不总是局域化的。在一定的阈值场强下，发生从功率局域准能本征态到扩展态的跃迁。
We study the quantum dynamics of a particle in a one dimensional triangular well under a monochromatic perturbation. Though the classical dynamics is described by the Standard Map, the quantum motion is not always localized. At a certain threshold field intensity, a transition takes place, from a, regime of power-localized quasi-energy eigenstates to one of extended states.
