Challenger Deep

[地名] [太平洋] 挑战者号海渊

This was in sharp contrast to a less publicised mission， to the paltry depth of2.5km， where the pressure is a mere 250 times that of the atmosphere ( thechallenger deep's pressure is four times that).

这与一项不太为人所知的行动形成了鲜明对比，后者只下潜到区区2.5千米，承受了250个大气压（挑战者深渊那里的压强四倍于此）。
