然而,一个驾驶舱语音记录器只能存储两个小时的驾驶舱语音 记录。
CVR存储了机组人员之间的对话和空中交通管制塔台的互动, 但也存储了背景噪音,若发生坠机,可以为调查人员提供重要 线索。
interaction n [课标新增词] [学术词] 交流(interact + -ion)
air traffic control 空中交通管制(员) give vital clues to 为……提供至关重要的线索
However, a cockpit video recorder can store only two hours of cockpit voice recording. The CVRs store the crew’s interactions with each other and air traffic control, but also background noise that can give vital clues to investigators in case of a crash.
approximately 14,000 feet.
如何追踪黑匣子? 黑匣子上配备有水下定位信标(ULB),如果飞机坠入水中, 信标会发出超声波脉冲,可被声纳和音频设备探测到,探测深 度约为14,000英尺。
trace v [学术词] 找到;发现;追踪
(be) equipped with sth 装有某物;配备有某物
这些往往是秘密的电子设备实际上被包裹在不反光的黑盒子或外壳中, 因此被称为“黑匣子”。 这些黑匣子的颜色是亮橙色。
often-secret adj 通常是秘密的 literally adv [课标新增词] 按字面;字面上 encase v 把……装箱(或围住、包起) (en- + case箱子) non-reflective adj 不反光的 hence adv [课标新增词] [学术词] 因此;由此 (近 therefore) flame-orange adj 橙红色的
How is a black box traced? Equipped with an underwater locator beacon (ULB), if an aircraft crashes into
water, the beacon sends out an ultrasonic pulse (超声波脉冲) that is detectable by sonar ( 声 呐 ) and audio ( 音 频 ) equipment to depths to
令人难以置信的是,该信标由电池供电,保质期为6年;一旦信标开始发 射信号,每秒发射一次,可持续30天,直到电池耗尽。 在深度达6,000米的海水中,黑匣子仍可继续工作。
incredibly adv [句子副词] 难以置信地(课标新增词 incredible + -ly) (近unbelievably) shelf life 保存期 run out 用完;耗尽
objectively adv [学术词] 客观地(object + -ive + -ly)
The CVR records the conversation between the pilots as well as with the air traffic control tower. The sounds of switches and engine are also recorded by the device.

Black Box 黑匣子
Airplane fatalities (死亡) are statistically rare. When they do happen, however, they are often fatal (致命的) and people want answers as to why their loved ones lost their lives, and that is where black boxes come into play. 从统计数据上看,飞机事故极少发生。然而,飞机事故一旦发 生,往往是致命的。人们想知道他们至爱的人的死亡真相,而 这就要用到黑匣子了。
黑匣子有什么作用? 飞行数据记录器和驾驶舱语音记录器是每个商业飞机或公务机 必须配备的,通常放置在飞机尾部,在这个位置它们更有可能 在坠机事故中保存下来。
compulsory adj (因法律或规则而)必须做的,强制的,强迫的
survive a crash 在坠机事故中保存下来
FDRs record things like airspeed, altitude, vertical acceleration and
有两种不同的飞行记录器设备:飞行数据记录器(FDR)通过其每 秒几次收集的几十个参数来记录飞行的最新历史数据;驾驶舱语 音记录器(CVR)保存驾驶舱内最近的声音数据,包括飞行员之间 的对话。
这两个设备可以组合成一套。一个黑匣子只有鞋盒大小。
What does a black box do? The flight data recorder and cockpit voice recorder are compulsory on every commercial flight or corporate jet, and are usually kept in the tail of an aircraft, where they are more likely to survive a crash.
fuel flow and has about 25 hours of recording storage.
Together, the FDR and CVR objectively document the aircraft’s
flight history, which may assist in any later investigation. FDR可以记录飞行速度、飞行高度、垂直加速度和燃油流量等 信息,并且可以存储25小时长的记录。
CVR记录了飞行员之间以及与空中交通控制塔台之间的对话。 该设备也会记录开关和发动机的声音。
the air traffic control tower 机场管制塔台 塔台是一个机场里最高的建筑,顶层360度的玻璃房子就是它的标志。 在这个玻璃房子里,空中交通管制员们要密切关注机场范围内每一 架飞机的状态,巧妙地管理着跑道资源,不间断地将满天的飞机安 全接到地面,再把满地的飞机安全送到天上。
underwate水下定位信标是民航客机黑匣子的重要部件之一。当飞机坠入水中 时,信标开始发送人耳听不到的超声波脉冲,这种脉冲可以被声纳 和声学定位仪探测到。在信标的一端有像公牛眼一样的水下传感器。 当水接触到传感器,信标就会被激活而发出超声波脉冲。
saltwater n 海水;咸水;盐水(salt + water)
If a plane crash takes place on land and not on water, the locator beacons of the black box will not send out the ultrasonic pings, signalling the investigators to look for the unit around the crash site.
FDR和CVR共同客观地记录了飞机的飞行历史,这对于以后的 任何调查都可能有帮助。
airspeed n (飞机的)空速(air + speed)
altitude n 高度;海拔
vertical acceleration 垂直加速度
fuel flow 燃油流量
storage n 存储(store + -age)
什么是黑匣子? 黑匣子是放置在飞机上的电子记录装置,可帮助调查航空事故和事 件。 黑匣子实际上就是飞行记录器。
There are two different flight recorder devices: the flight data recorder (FDR) preserves the recent history of the flight through the recording of dozens of parameters (范围) collected several times per second; the cockpit (驾驶舱) voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. The two devices may be combined in a single unit. A black box is the size of a shoe box.
如果飞机失事地点为陆地而非海上,黑匣子的定位信标就不 会发出超声波脉冲,这意味着调查人员需要在失事地点周围 寻找该装置。
signal v [名词动化] 发信号;发暗号;示意
Black box is not black The term “black box” was a World War II British phrase, originating with the development of radio, radar (雷达), and electronic navigational aids in British and Allied combat aircraft (盟军战斗机).
statistically adv [学术词] 统计地(statistics + -al + -ly)
come into play 起作用;有影响
What is a black box? A black box is an electronic recording device placed in an aircraft for to facilitate (使便利) the investigation of aviation (飞行) accidents and incidents. Black boxes are actually known as flight recorders.
detectable adj [学术词] 可检测到的;可发现的(detect + -able)
approximately adv [学术词] 大约;大概(approximate + -ly)
Incredibly, the beacon is powered by a battery that has a shelf life of six years; once the beacon begins pinging (发出信号), it pings once per second for 30 days until its battery runs out. The black box works in depths up to 6,000 metres of saltwater.
黑匣子并不是黑色的 “黑匣子”一词是二战时期英国的用语,起源于英国和盟军战斗机的 无线电、雷达和电子导航辅助设备的发展。
originate v 起源;发源 electronic navigational aids 电子助航设备
These often-secret electronic devices were literally encased in non-reflective black boxes or housings, hence the name “black box”. These black boxes are of fluorescent (发荧光的) flame-orange in colour.
