On the basis of analysing the mechanism of improvement of the adsorption mass transfer by ultrasound field , a batch model cosindering pore difusion and surface diffusion , and a fixed - bed homogeneous model of mass transfer is developed . 论文在分析超声场强化固-液吸附传质的机理上,提出了考虑孔内扩散与表面扩散的静态传质模型以及考虑轴向扩散的均相动态传质模型。
The result of the experiment indicated that the capability of adsorption decrease with ultrasound intensity , while the rate of the extraction and adsorptin increase . the model resulst also showed that the theoretical value of the homogeneous model considering intrapartical diffusion and outside - surface diffusion with freundlich phase equilibrium equation are agfeeable with the experimental value 在吸附实验中,测定了不同强度超声场下栀子甙与1300树脂上吸附平衡曲线、静态吸附动力学曲线、动态穿透曲线。实验结果表明,吸附容量随着超声波强度的增加而减少,而浸取、吸附速率随着超声波强度的增加而增大。
And considerable work has been done hi the growth behaviour in the tetrachloride solution concluding studies of crystal growth and growth kinetics . a crystal of dimensions 20mm x 20mm x 1mm was produced hi the tetrachloride solution by lowing temperature . and bcf spiral growth mechanism for the surface diffusion model was analyzed using the kinetic data 本文以苯为溶剂溶液降温法培养出了60mm 40mm 3mm大尺寸hhm单晶;另外探讨了hhm在四氯化碳溶液中的生长行为,溶液降温法培养出了20mm 20mm 1mm的较大尺寸单晶,并用动态循环体视显微镜观察法测定了其在不同的过饱和下主要显露晶面的法向生长速率,在较大过饱和度范围内考察了其bcf表面扩散螺位错生长机制。
