解释这些现象需要新的方法产生氧化剂，这种氧化剂却无法改变大气层中其他化学物质的平衡。
Explaining these requires new ways of producing oxidising power which do nothing to alter the balance of other chemicals in the atmosphere.
如果气体易燃、有腐蚀性、有毒或是氧化剂，采取合适的措施通过在把气体排入大气之前使用适当废弃物处理系统使它变得无害。
If the gas is flammable, corrosive, toxic, or an oxidant, take appropriate measures to render it innocuous by employing a suitable disposal system before venting the gas to the atmosphere.
大气氢氧自由基(OH)是对流层大气中的主要氧化剂之一，在大气化学过程中占有重要地位。
Hydroxyl radical (OH) is one of the most important species in the atmosphere as a major oxidant.
她说，我们在研究蒸汽相的酯化反应，在一定的大气压下，氧气为氧化剂，通过金属纳米孔道反应，其效果良好。
'We are currently investigating vapour-phase esterification reactions over metallic nanoporous gold using O2 as the oxidant at atmospheric pressure with encouraging results, ' she says.
