| 5. | Interestingly , these two issues are highly related , because energy consumption usually produces carbon dioxide ( co2 ) which is the major cause of climate change
有趣的是这两项课题具有高度的相关性，因为能源消耗通常会产生二氧化碳，而二氧化碳则是引起气候变迁的主因。 |
| 6. | Recent observations made with themis instrument onboard nasa ' s mars odyssey , currently orbiting mars , found the spots to be as cold as the carbon dioxide ( co2 ) ice beneath them
正在探索火星的火星奥德赛号探测船，最近用搭载的themis相机进行的观测，发现这些暗斑和它下方的乾冰一样冷。 |
| 7. | Today the world ' s coal , oil and natural gas industries dig up and pump out about seven billion tons of carbon a year , and society burns nearly all of it , releasing carbon dioxide ( co2 )
今天，全球的煤、石油及天然气产业，一年挖掘及抽出大约70亿吨的碳，而社会大众几乎将它们全部烧掉，释放出二氧化碳。 |
| 8. | Unless humanity takes prompt action to strictly limit the amount of carbon dioxide ( co2 ) released into the atmosphere when consuming coal to make electricity , we have little chance of gaining control over global warming
除非人们立刻采取行动，严格限制燃煤发电时释放到大气的二氧化碳排放量，否则我们不太可能控制得了全球暖化的状况。 |
| 9. | In this paper , we employ the plasma enhanced chemical vapor deposition ( pecvd ) to prepare high quality zno thin film at low temperature using a zinc organic source ( zn ( c2h5 ) 2 ) and carbon dioxide ( co2 ) gas mixtures . the effect of the substrate temperature and annealing temperature on the quality of zno thin films was studied in detail
为了在低温下制备高质量的氧化锌薄膜，我们采用金属有机源和二氧化碳气源，首次利用等离子体增强化学气相沉积的技术在低温下制备了高质量的氧化锌薄膜，确定了生长高质量氧化锌薄膜的优化条件；研究了不同的衬底温度和退火温度对氧化锌纳米薄膜质量的影响。 |
| 10. | In order to otain high quality zno thin films , we , for the first time , employ the plasma enhanced chemical vapor deposition ( pecvd ) to prepare high quality zno thin film at low temperature using a zinc organic source ( zn ( c2h5 ) 2 ) and carbon dioxide ( co2 ) gas mixtures . the effects of the growing condiction and the native oxide layer of si substrate on the quality of zno thin films was studied in detail . to prepare p - zno and overcome the dufficulty of reverse due to the interaction between the n atomic , we obtain high qulaity p - zno by a easy way of thermal zn3n2
