| 摘 要： | We study the effect of Landau--Zener (LZ) tunneling caused
by the varying sweeping rate of the external field, and solve the
problem about the LZ tunneling rate among many levels. The LZ
tunneling rate is essentially changed by the unsteady variation of
the time-dependent sweeping field and is different from the steadily
varying sweeping field, which makes the particles in lower states
transit periodically to upper states within a finite time.
