VOA慢速英語:美滑翔機計劃在明年打破2.7萬米高度紀錄

Gliders are light aircraft that fly with no engine. They are pulled by a powered plane into the sky and set free to fly on air currents. They soar on wind currents called "mountain waves." That is why their wings are longer than ordinary planes.
滑翔機是輕型飛機，起飛不需要發(fā)動機。它們被動力飛行器拉動，飛向天空，并且可以自由在暖氣流中飛行。它們在“地形波”氣流中飛翔。這就是為什么它們的機翼要比普通飛機的長。
The aerospace company Airbus Group recently completed the first flight of a glider it calls Perlan 2. The Perlan Project intends to use gliders to take measurements in thestratosphere. Scientists believe weather in the stratosphere affects the Earth's climate more than they thought before.
空中巴士航空航天公司最近完成了滑翔機的首次飛行。它被命名為Perlan 2。Perlan項目旨在在平流層中使用滑翔機來測量?？茖W(xué)家們認為平流層的天氣狀況會影響地球氣候。影響程度超過他們之前所認為的。

Project Aims to Study Stratosphere Via Aerospace Firm's Glider |
Airbus plans to send Perlan 2 to an altitude of 27 kilometers next year. That is higher than the records set by the U-2 and SR-71 spy planes.
明年，空中巴士航空航天公司計劃將Perlan 2送至2.7萬米的高空。這將高于由U-2與SR-71偵察機所創(chuàng)造的記錄。
Jim Payne is the chief pilot of Perlan 2.
吉姆·佩恩是Perlan 2的首席飛行員。
"We're not a thousand percent sure that the mountain wave will go that high, but all the meteorologists tell us that it does, so we're going to go out and find out."
“我們并不能百分之一千的確定地形波會那么高，但所有的氣象學(xué)家告訴我們它確實是這么高。因此我們要刻意去做并且要查明。
Ed Warnock is the chief executive officer of the Perlan Project.
埃德沃諾克是該項目的首席執(zhí)行官。
He says the project intends to discover how fast moving winds at altitudes between 10 and 50 kilometers influence the earth's climate.
他表示，該項目旨在探索如何在海拔為1萬米至5萬米的高空快速的移動風(fēng)向，來影響地球氣候。
"It turns out some of the biggest waves in the world -- vertical movements -- exist in the stratosphere. We're going to go and study those waves. Those waves change weather and they change climate, and we are going to study how do they do that." Visit the website www.chinavoa.com to get more information!
“事實證明，在世界上一些最大的波——垂直運動——存在于平流層中。我們將對這些波進行研究。這些波可以改變天氣，改變氣候，并且我們將要研究這些波是如何改變天氣及氣候的。
Stratospheric winds may also influence commercial air traffic. Many airplanes fly at high altitudes to reduce fuel consumption.
同溫層風(fēng)也會影響商業(yè)的空中交通。很多飛機在高空飛行，以降低燃料消耗。
The air density, or thickness, at those altitudes is similar to the atmosphere on the planet Mars. This may lead to future aircraft designs that could someday fly through the skies of the Red Planet.
這一高度空氣的密度與厚度與火星大氣層中的相似。這可能導(dǎo)致未來對飛機設(shè)計，在某一天，將可能在這顆紅色星球的天空飛翔。
