heavier-than-air

heavier-than-air

美 　英

• 網絡比空氣重的；重于空氣航空器

英漢解釋

adj.	1. unable to float in air because it weighs more than the air it displaces, and thus only able to fly under power using aerodynamic lift

例句

Spills would also be a health risk, since carbon dioxide is heavier than air, and so can build up in low-lying or poorly ventilated spots.

二氧化碳泄漏會帶來健康風險。由于二氧化碳比空氣重，因此可以在低洼地區和通風差的地區累積。

With a wing and one refers to one or more with the engine, relying on its own power to fly in the atmosphere heavier than air aircraft.

指具有機翼和一具或多具發動機，靠自身動力能在大氣中飛行的重于空氣的航空器。

People called the Wright brothers mad but it did not stop them from becoming the first men to construct and fly a heavier-than-air craft.

人們說萊特兄弟瘋了，然而這并沒阻止他們成為最早建造并駕駛比空氣更重的飛行器的人。

Any of various winged vehicles capable of flight, generally heavier than air and driven by jet engines or propellers.

各種能夠飛行的帶翼交通工具，通常比空氣重，用噴氣式發動機或螺旋槳驅動

I say "catastrophic" because carbon dioxide is heavier than air, and a ground-hugging cloud would suffocate anyone it enveloped.

我用到“災難性”一詞，是想說二氧化碳比空氣質量重，當二氧化碳形成的云層過重，空氣銳減，所有下面的人都會窒息而死。

Some gases used are not necessarily toxic, but can be heavier than air, thus displacing oxygen and creating a breathing safety hazard.

測試中使用的某些氣體未必有毒，但可能比空氣重，因此可能取代氧氣并帶來安全呼吸危險。

Therefore, a precise definition of the aircraft is: there is a power-driven aircraft, fixed wing aircraft and is heavier than air.

因此飛機的精確定義就是：飛機是有動力驅動的有固定機翼的而且重于空氣的航空器。

But it is worth remembering that just over a century ago, heavier-than-air flight seemed an impossible dream.

但是值得回憶的是僅僅在一個世紀以前，重于空氣的飛行似乎是個不可能實現的夢想。

That day they became the first people to demonstrate sustained flight of a heavier-than-air machine under the complete control of the pilot.

他們在那天也率先成為完全掌控這架比空氣還重的機器而持續飛行的人。

Because CO2 is 40% heavier than air, placement of exhaust vents at or near ground level is recommended when blasting in an enclosed area.

因為CO2比空氣重40%，所以在封閉區域進行噴射時，建議將排氣孔放置在地面上或接近地面的位置。

An aircraft towing objects has the right of way over all power -driven heavier - than -air aircraft.

與重于空氣的動力驅動飛機相比，帶有牽引物體的飛機享有優先權。

Sometimes the craft is heavier than air, and sometimes lighter.

有時飛行器比空氣重，有時輕。

Under normal atmospheric conditions, carbon dioxide exists as a colorless, odorless gas which is about 1. 5 times heavier than air.

在正常大氣壓下，二氧化碳是無色無味氣體，密度比空氣大，是空氣的1.5倍。

Aeroplanes shall give way to power -driven heavier - than -air aircraft.

飛機應該給重于空氣的動力驅動飛機讓路。

Power -driven heavier - than -air aircraft shall give way to gliders.

重于空氣的動力驅動飛機應該給滑翔機讓路。

Named after Samuel Pierpont Langley (1834 - 1906), American astronomer, physicist, and pioneer in the development of heavier-than-air craft.

塞繆爾·蘭利（1834年-1906年）美國天文學家，物理學家，航空先驅。航母以蘭利為艦名。

Carbon dioxide in pure form can asphyxiate because it is heavier than air.

因為二氧化碳比空氣要重，純凈的二氧化碳可以使人窒息。

Cold air is heavier than air, easy to sink;

冷氣流比空氣重，易下沉；
