you every time you fly.They record where you're going,how fast you're traveling and whether everything on your airplane is functioning normally.Their ability to withstand almost any disaster makes them seem like something out of a comic book.They're known as the black box.When planes fall from the sky,as a Yemeni airliner did on its way to the Comoros Islands in the Indian Ocean June 30,2009,the black box is the best bet for identifying what went wrong.So when a French submarine (潜水艇) detected the device's homing signal five days later,the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.In 1958,Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction.That was the first model for a black box,which became a requirement on all US commercial flights by 1960.Early models often failed to withstand crashes,however,so in 1965 the device was completely redesigned and moved to the rear of the plane—the area least subject to impact—from its original position in the landing wells (起落架舱).That same year,the Federal Aviation Authority required that the boxes,which were never actually black,be painted orange or yellow to aid visibility.Modern airplanes have two black boxes:a voice recorder,which tracks pilots' conversations,and a flight-data recorder,which monitors fuel levels,engine noises and other operating functions that help investigators reconstruct the aircraft's final moments.Placed in an insulated (隔绝的) case and surrounded by quarter-inch-thick panels of stainless steel,the boxes can withstand massive force and temperatures up to 2 000°F.When submerged,they're also able to emit signals from depths of 20 000 ft.Experts believe the boxes from Air France Flight 447,which crashed near Brazil on June 1,2009,are in water nearly that deep,but statistics say they're still likely to turn up.In the approximately 20 deep-sea crashes over the past 30 years,only one plane's black boxes were never recovered.

第一句不是那个 是you never see them,but they are with you every time you fly.

Answer 1

你从未见过他们,但每次你飞翔的时候他们都在伴随着你.他们记录你去往的地点,旅行的速度及飞机上的所有功能是否正常运作.那种几乎可以抵抗任何灾难的能力使得它们看起来像来自某本喜剧书,他们被称为“黑匣子”,当飞机坠落时,黑匣子是证明飞机哪里出现故障的最好方式,如2009年6月30日印度海域科一架也门客机前往摩罗群岛路上事故,当一艘法国潜水艇在事发五天后侦测到设备的返航信号,这一发现为决定造成152名乘客死亡这一悲剧的原因做出了重要贡献.
在1958年,澳大利亚科学家大卫沃伦研发了一个飞行记忆纪录机,能够追踪诸如高度方向等基本信息.这是发明黑匣子的首个模型体,并且至1960年已成为美国所有商业班机的必备物品.早期模型不能抵抗飞机的坠毁,然而,由于这样,在1965年这项设备被完全重新设计并且移到飞机后端位置--受冲击最小的地方--由原先的起落架舱位置.同一年,联邦航空部门要求这些原本就不是黑色的匣子,图上橙色或黄色以提高能见度.当代飞机有两个黑匣子：一个声音纪录机,用于记录飞行员的谈话.一个飞行数据记录机,用于监控染料等级,引擎声音大小及其他用来帮助调查者重构飞机坠毁前一刻的运行功能.黑匣子被放置在隔绝的箱子中,周围是四分之一寸厚的不锈钢面板,它能够抵抗巨大的冲击力和2000华氏度,也可以在水下20000英尺深时发出信号.专家们确信2009年6月1日巴西附近发生的法国航空447号班机空难后的黑匣子,就是在接近20000英尺深的水底,但统计学称他们仍然可能出现.在过去30年里将近20起的深海坠机事件中,只有一架飞机的黑匣子没能被还原.
