| 2. | Carbon dioxide ( co2 ) combines with water to form carbonic acid ( h2co3 ) , the same weak acid found in carbonated beverages 二氧化碳( co2 )和水结合,形成碳酸( h2co3 ) ,这种弱酸也可以在碳酸饮料里找到。 |
| 3. | Another obvious candidate was carbon dioxide ( co2 ) , one of the primary gases spewing from the volcanoes abundant at that time 另一个当然候选者则是二氧化碳( co2 ) ,它是当时活跃的火山活动所喷出的主要气体之一。 |
| 4. | The pvc tube is hazardous for carbon dioxide ( co2 ) laser surgery if it is not well wrapped with metallized foil tape 在雷射手术当中,如果气管几管用金属铝箔纸包覆的不完备的话,尤一管子被雷霆央求我束打到,造成起火燃烧的机会还是很大。 |
| 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 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,系统地研究了生长条件以及衬底表面氧化层对薄膜质量的影响,确定了生长高质量氧化锌薄膜的优化条件;为获得p - zno材料,克服在zno中掺n杂质间相互作用影响掺杂效率不易获得p - zno的困难,我们通过热氧化zn3n2的方法制备了p - zno ,获得了一系列研究结果: 1 、详细研究了气体流速比,衬底温度和射频功率实验参数对氧化锌薄膜特性的影响。 |
