1.
A new approximate concentration profile model for batch adsorption in a spherical adsorbent is proposed.
引 言间歇吸附是一非稳态过程 ,用线性等温吸附扩散方程的解析解来描述单个吸附剂的非稳态吸附过程过于复杂[1~ 3] ,许多学者试图用多项式函数模拟吸附剂中随时间变化的吸附质浓度分布侧形 。
2.
By comparing the surface diffusion model with the pore diffusion model in batch adsorption of activated carbon fiber with Langmuir isotherm, we gave the relationships between the surface diffusivity and the pore diffusivity, and analysed if one can use the batch adsorption system to research the mechanism of diffusion .
比较了活性炭纤维间歇系统当吸附等温方程为Langmuir型时表面扩散模型与孔扩散模型,获得了两模型扩散系数可相互转换的条件,分析了用间歇吸附实验研究溶质在活性炭纤维内扩散机理的可行性,同时给出当吸附等温方程为矩型时两模型的解析解。
3) interval load
间歇加力
4) intermittent heating
间歇加热
1.
Drying process of small-diameter lumbers with intermittent heating;
间歇加热小径木锯材干燥工艺
5) intermittent feeding
间歇补加
1.
On the basis of the growth and metabolism behavior inherent in suspended Sf21 insect cells,the intermittent feeding of growth limiting nutrients(glucose and protein hydrolysates)was employed in the regulation of cellular growth during the cultivation by using the residual glucose concentration as a reference point.
基于Sf2 1昆虫细胞在悬浮培养过程中所表现出的生长代谢特征 ,提出以培养液中残糖浓度作为控制参数 ,并利用限制性基质 (葡萄糖和蛋白水解物 )的间歇补加技术调控细胞生长的方案。

特性吸附与半胶束吸附
specifical adsorption and hemi-micelle adsorption
texing xifu yu banJ旧oshu xifu特性吸附与半胶束吸附(speeifieal adsorp-tion and hemi一mieelle adsorption)矿物一水界面的吸附的两种形式。特性吸附是因矿物表面与溶液中某种组分(离子或分子)有特殊的亲和力而产生的吸附,也称特殊吸附。特性吸附不仅可以改变电位的数量而且还可以改变电位的符号。例如,刚玉(A12O3)在NaZSO‘或RSO;Na(烷基硫酸钠)溶液中,电动电位随溶液浓度的增大由正值逐渐减小,直至变为负值,说明刚玉对50矛一或RSO不离子有特殊的吸引力。半胶束吸附是水溶液中的表面活性剂在矿物表面产生的吸附,当吸附量达到一定值以后,由于烃基的缔合作用,表面活性剂的离子或分子在矿物表面上形成紧密的吸附层,这类似于溶液中形成的胶束结构,但所形成的“胶束”与溶液中形成的胶束不同,只有二维空间,故称这类吸附为半胶束吸附。矿物表面对胺类捕收剂的吸附,当胺的浓度较大时,常可以产生半胶束吸附。 (龚焕高)
