摘要

利用扩散自由体积模型

通过一定的线性假定将凝胶及固定化细胞中的自由体积与各主要影响因素相联系

得到了能表达诸因素对有效扩散系数影响的改进的扩散自由体积模型.其特点是不仅能反映凝胶总单体浓度、交联度及扩散分子大小的影响

而且可以反映温度及细胞浓度对有效扩散系数的影响.

Abstract

A modified free volume model of diffusion has been developed to interpret transport phenomena in gel and immobilized cell matrix. With a set of formulas deduced from the model

the dependence of the effective diffusivity on such factors as gel composition (monomer concentration and crosslinking degree)

cell loadings and temperature can be correlated by four linear relations.
