| 摘 要： | 微波场协同溶质扩散机理是强化传质研究的苇要内容,由于微波热效应的干扰,微波场协同极性分子扩散的实验研究尚未取得大的进展.基于液体扩散机制,利用微波场对偶极分子的作用以及分子间相互作用能的影响,建立了微波场协同溶质分子扩散的关系式,得出了微波协同极性分子扩散是通过改变分子间的相互作用能来增强溶质分子扩散的结论.微波场的协同作用依赖分子的电偶极矩,温度较高时,电偶极矩越人强化效果越明显.微波场还可以通过削弱分子问动态氢键来增大扩散通量.该结论可为微波强化传质的理论和实验研究提供参考. |

| Abstract: | The mechanism of microwave field synergy in the enhancement of solute diffusion is im- portant in mass transfer enhancement research. Because of the disturbance of microwave thermal effect, no obvious progresses were made in the experimental study of microwave synergy with polar molecule diffusion. With the liquid diffusion theory, and based on the action principle of microwave on electric dipole of polar molecules, the theoretical expression of solute diffusion flux as functions of electric field as well a... |
