文章：

Line	Most attempts by physicists to send particles
	faster than the speed of light involve a remarkable
	phenomenon called quantum tunneling, in which
	particles travel through solid barriers that appear
(5)	to be impenetrable. If you throw a ball at a wall,
	you expect it to bounce back, not to pass straight
	through it. Yet subatomic particles perform the
	equivalent feat. Quantum theory says that there is a
	distinct, albeit small, probability that such a particle
(10)	will tunnel its way through a barrier; the probability
	declines exponentially as the thickness of the
	barrier increases. Though the extreme rapidity of
	quantum tunneling was noted as early as 1932,
	not until 1955 was it hypothesized—by Wigner and
(15)	Eisenbud—that tunneling particles sometimes
#160;	travel faster than light. Their grounds were
	calculations that suggested that the time it takes a
	particle to tunnel through a barrier increases with
	the thickness of the barrier until tunneling time
(20)	reaches a maximum; beyond that maximum,
	tunneling time stays the same regardless of
	barrier thickness. This would imply that once
	maximum tunneling time is reached, tunneling
	speed will increase without limit as barrier thickness
(25)	increases. Several recent experiments have
	supported this hypothesis that tunneling particles
	sometimes reach superluminal speed. According to
	measurements performed by Raymond Chiao and
	colleagues, for example, photons can pass through
(30)	an optical filter at 1.7 times the speed of light.
