基本解釋

The feasibility of ETT (Evacuated Tube Transportation)has been verified by foreign and domestic experts.
真空管道運輸?shù)目尚行砸呀?jīng)得到國內(nèi)外專家的論證。
Instantaneous efficiency curves for both single evacuated tube and complete evacuated tubular collector are also tested.
通過實驗，還分別測定了單根真空管和真空管集熱器的瞬時效率曲線。
Borosilicate is also a material of choice for evacuated tube solar thermal technology, because of its high strength and heat resistance.
硼硅酸鹽也是材料的選擇真空管太陽能熱技術(shù)，由于其高強度和耐熱性。

So we'll take h 2 and we'll run -- or actually we'll have h 2 filled in an evacuated glass tube.
我們馬上就會在氫原子上試一試,我們用氫氣-我們把玻璃管充滿氫氣。
