今天，全球的煤、石油及天然氣產(chǎn)業(yè)，一年挖掘及抽出大約70億噸的碳，而社會大眾幾乎將它們全部燒掉，釋放出二氧化碳。 - 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
除非人們立刻采取行動，嚴格限制燃煤發(fā)電時釋放到大氣的二氧化碳排放量，否則我們不太可能控制得了全球暖化的狀況。 - 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
為了在低溫下制備高質量的氧化鋅薄膜，我們采用金屬有機源和二氧化碳氣源，首次利用等離子體增強化學氣相沉積的技術在低溫下制備了高質量的氧化鋅薄膜，確定了生長高質量氧化鋅薄膜的優(yōu)化條件；研究了不同的襯底溫度和退火溫度對氧化鋅納米薄膜質量的影響。 - 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
