TNT爆轰生成纳米金刚石晶核生成和长大的估计

ESTIMATION ON THE NUCLEATION RATE AND THE CRYSTAL GROWTH VELOCITY OF ULTRAFINE DIAMOND IN TNT DETONATION

以实验测定的爆轰压力和比容等空间分布参数为依据，用简单理论估算温度和反应度，用晶粒均匀成核和长大理论估算了TNT爆轰游离碳在上述热力学条件下的金刚石成核和长大过程，估算的金刚石得率与实验值相符。

Based on experimental data, reactivity and temperature at various points of time in the TNT detonation reaction zone and Taylor zone are calculated.The nucleation and the growth of diamond from free carbon as is formed in the TNT detonation reactive zone have been estimated by classical homogeneous crystal nucleation and growth theory. The estimated yield of ultrafine diamond is in agreement with that from the experimental data.
