查询词典 dioxide

Paleoclimate evidence suggests that the Toba eruption, which occurred during the last ice age, emitted lots of sulfur dioxide--vastly more than Mount St. Helens did.

Therefore, we must take the necessary measures to reduce the environmental impact of carbon dioxide. For example: tree-planting activities, reduce fossil fuel use, we can from our own, to promote low-carbon living.

因此，我们必须采取必要措施减少二氧化碳对环境的影响，例如：搞植树活动、减少石油燃料的使用，我们可以从我们自己做起，倡导低碳生活。

Friction and wear behavior of CrNiMo steel against H96 brass in different atmosphere s like oxygen and carbon dioxide were investigated on the MMS-1G tribometer under high speed and dry sliding.
