The apparent activation energy,the adsorption heat and the activation energy of surface reaction were 71.5kJ/mol,34.9kJ/mol and 106.4kJ/mol,respectively. 吸附热34.
This new two dimensional surface states model explains the origin of surface states and the contradiction between deep surface levels and the low activation energy of a transient current. 用该态模型解释了氮化物产生高密度表面态的原因和深表面能级与较浅的瞬态电流激活能间的矛盾。
It appeared that electrochemical dyeing could not only increase equilibrium up-take of dyes,accelerate the rate of diffusion and reduce active energy of dyeing,but also reduce cost and save energy. 试验结果表明,在一定电压下,电化学染色技术可以提高还原染料的平衡上染百分率,加快扩散速率,降低染料上染的活化能,降低成本,节约能源。
A great impact of surface diffusion on CVD diamond nucleation is discovered and investigated. 发现和研究了表面扩散对CVD金刚石成核的重要影响。
