氢气

Hydrogen is a corlorless, odorless gas.

氢是一种无色、无味。

The system can easily change coflow temperature, oxygen mole fraction and turbulence parameters by changing the coflow mixture equivalence ratio.

该试验装置利用氢／空预混高温产物来成可控活化热氛围，能方便地通过改变协流当量比而改变协流热氛围、氧氛围和湍流场。

Explanation: Cosmic clouds of hydrogen gas and dust abound in this gorgeous skyscape, stretching through Monocerous in the neighborhood of The Cone Nebula.
