It was a brilliant sight. The terrific heat from the first nozzle caused the metal to glow under the torch as if in an open-hearth furnace. From the second nozzle issued a stream of oxygen under which the hot metal of the door was completely consumed. The force of the blast as the compressed oxygen and acetylene were expelled carried a fine spray of the disintegrated metal visibly before it. And yet it was not a big hole that it made--scarcely an eighth of an inch wide, but clear and sharp as if a buzz-saw were eating its way through a three-inch plank of white pine.英文原著 · 《The Silent Bullet》
"You remember when we were talking on the drive about the raid, O'Connor? A car-load of scrap-iron went by on the railroad below us. They use this blowpipe to cut it up, frequently. That's what gave me the idea. I turn on the oxygen now in this second nozzle. The blowpipe is no longer an instrument for joining metals together, but for cutting them asunder. The steel burns just as you, perhaps, have seen a watch-spring burn in a jar of oxygen. Steel, hard or soft, tempered, annealed, chrome, or Harveyised, it all burns just as fast and just as easily.英文原著 · 《The Silent Bullet》
Nitric Acid--Exists in combination with the bases, potash, soda, lime, magnesia, in both the mineral and vegetable kingdoms, and is never found insoluble. It has the same constituents as common air, but in different proportions. The strongest nitric acid contains in every pound, two and a quarter ounces of water. Pure nitric acid is colorless, with a specific gravity of 1.5, and boiling at 248 deg.. It is a most powerful oxidizing agent, and is decomposed with more or less rapidity, by almost all the metals, to which it yields a portion of its oxygen.英文原著 · 《American Hand Book of the Daguerreotype》
The common sulphuric acid is made by burning sulphur, which forms sulphurous acid. To convert this into sulphuric acid and gain more oxygen, nitric acid, which is rich in that body, is added. It forms a limpid, colorless fluid, of a specific gravity of 1.8. It boils at 620 deg.; it freezes at 15 deg. It is acrid and caustic, and intensely acid in all its characters, even when largely diluted.英文原著 · 《American Hand Book of the Daguerreotype》
Morten Kiil. Very comfortable--plenty of fresh air. I should think you have got enough to-day of that oxygen you were talking about yesterday. Your conscience must be in splendid order to- day, I should think.英文原著 · 《An Enemy of the People》
[1] Green vitriol, ferrous sulphate heptahydrate, a compound of iron, sulphur, and oxygen, crystallised with seven molecules of water, represented by the formula FeSO4<.>7H2O. On exposure to the air it loses water, and is gradually converted into basic ferric sulphate. For long, green vitriol was confused with blue vitriol, which generally occurs as an impurity in crude green vitriol. Blue vitriol is copper sulphate pentahydrate, CuSO4<.>5H2O.英文原著 · 《Bygone Beliefs》
Go, Max, I'm running out of oxygen, and I think there was cheese in here.美剧 · 《2 Broke Girls》
But the one thing more important than giving oxygen to the fire of Axe Cap is keeping my escape hatches open in case those pricks from the government ever come after me again.美剧 · 《Billions》
And very few people can even survive on the available oxygen up here.美剧 · 《Billions》
