n.隧道效應(yīng)；開挖隧道

動詞tunnel的現(xiàn)在分詞形式.

The sensors rely on quantum tunnelling, in which electrons take journeys that would not be allowed by the laws of classical physics, as long as the distances involved are tiny. 這些傳感器根據(jù)量子隧道效應(yīng)的原理工作，即只要間隔的距離非常微小，電子就能穿過經(jīng)典物理學(xué)認(rèn)為不能通過的勢壘。
