摘要：
We consider transmission and reflection of narrow Gaussian wave packets by delta potentials in the cases of constant and specific (inverse linear) time-dependent strength. Both transmitted and reflected packets exhibit some 'squeezing' in the momentum probability distributions. Several different definitions of the transmission time are introduced and compared.
