摘要
通过对方程中把作为产物层增厚速率的基础作出分析,对由扩散控制的固相反应中扩散浓度与时间的关系作了进一步探讨,提出产物层增厚速率应建立在Fick第二定律的基础上,并导出了新的扩散动力学方程.
The shortcomings that the rate of thickening of the reaction product basad on in Ginstling equation are analysed. Further relation of the diffusion density versus time in diffnsion controlled solid reactions is studied. The reason that the rate of thickening of the reaction product should be based on is discussed and a new diffusivity-dynamics oquation is proposed.
