Once it has passed through the slits, the photon strikes a position sensitive detector.

一旦它通过通过狭缝，光子就会击中位置灵敏探测器。

For instance, when a neutrino strikes the detector in Gran Sasso, that signal has to travel 8km through a waveguide before a timing measurement can be made.

例如，当一个中微子击中格朗萨索的检测器后，该信号必须通过波导管传送8公里方能进行时间测量。

When you go through a metal detector at the airport with a conductor such as keys in your pocket, the alarm goes off.

当你带着一个导体（比如口袋的钥匙）走过机场的金属探测器时，机器会发出警报声。

Abdulmutallab then passed through a walk-through metal detector and put his shoulder bag through an X-ray screening machine, Demuren said.

As dark matter particles steam through the detector, scientists hope that a few will collide with the argon atoms.

Naturally occurring neutrinos from cosmic rays, supernovae and the sun stream through the detector at the same time.
