The result shows that the influence of the conditions of synthesizing nano-carrier Al_2O_3 on apertures distribution of carrier follows the sequence: ageing time, NH_4HCO_3 excess coefficient, reaction temperature, charging-up way, and Al~ ( 3+) concentration. 结果表明,纳米载体Al2O3的合成条件对其孔径分布的影响顺序依次为陈化时间、NH4HCO3的过量系数、反应温度、加料方式及Al3+浓度。
