Identify the volatile product and comment . 鑒定此揮發(fā)性產(chǎn)品并評述。
This integration is crucial in a facility such as a chemical plant , where volatile products make for dangerous working environments 這一集成在化工廠等地方非常關鍵,因為這些地方的揮發(fā)性產(chǎn)品會導致產(chǎn)生危險的工作環(huán)境。
Ammonia played a critical role in the vertical alignment of cnts , and the possible reason was that in 850 the atomic hydrogen decomposed from ammonia reacted with amorphous carbon to form volatile products to keep the metal surface clean , and mechanical leaning against neighboring tu bes established a morphology of vertical alignment 當基體為單晶硅、催化劑鎳膜厚度為20nm 、氨氣氣氛、生長溫度為850時,得到了定向生長的納米碳管。其原因可能是850時氨氣分解的氫原子和無定形炭生成了易揮發(fā)物質(zhì),從而保持催化劑的活性使納米碳管依靠相鄰碳管之間的斥力定向生長。
