炭生成 meaning in Chinese

char formation

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
当基体为单晶硅、催化剂镍膜厚度为20nm 、氨气气氛、生长温度为850时，得到了定向生长的纳米碳管。其原因可能是850时氨气分解的氢原子和无定形炭生成了易挥发物质，从而保持催化剂的活性使纳米碳管依靠相邻碳管之间的斥力定向生长。
