| 6. | But the quantification of nitrous - oxide emissions is still not well understood , says dr williams , so it is not clear which model to use 但是,威廉姆博士说,一氧化二氮气体的具体排放量目前还没有人们完全了解,因此也无法决定该具体使用哪一种模拟方式。 |
| 7. | To complicate matters further , nitrous - oxide and methane emissions from farms far outweigh carbon - dioxide emissions in global - warming potential 为了将此焦点话题更加复杂化,一氧化二氮气体与沼气的排放量在全球变暖潜在因素中远远超过了二氧化碳的排放量并更具危害性。 |
| 8. | Methane and nitrous oxideare taken into account by converting them into “ carbon - dioxide equivalent ” emissions using conversion factors provided by the intergovernmental panel onclimate change 人们已经在考虑将沼气与一氧化二氮气体使用由气候变化政府专门小组提供的转换因子转换为二氧化碳的对等物。 |
