On the base of analyzing and comparing merits and drawbacks of the available matrices for eba , the author put forward his study idea , which adopted the composite of regenerated cellulose and superfine tio2 , respectively as reactive matrix and densifier , to prepare a spherical hydrophilic matrix for eba 在分析和比较已有扩张床基质优缺点的基础上，作者提出了自己的研究思路，即采取再生纤维素和超细钛白粉分别作为反应性骨架材料和增重剂，复合制备出球形亲水性扩张床基质。
