| 英文摘要 | a traversal time that has no problem of supertuminality was advanced for particles to runnel through potential barriers in the non-relativistic quantum theory in a previous paper by c.-f. li and q. wang, physica b 296 (2001) 356. this time is generalized in this paper to dirac's relativistic quantum theory. both evanescent and propagating cases are considered. it is shown that the traversal time in the evanescent case has much the same properties as in the, non-relativistic quantum theory and thus has no problem of superluminality. it also gets rid of the problem of superluminality in the propagating case. comparisons with the dwell time, the group delay, and the velocity of monochromatic front are also made. |
