在50%的BL/Lmin比值下，两组差异亦存在显著性意义，这种差异主要由于斜视组P100单眼最小峰时与双眼峰时明显不同所致。

The features of AAA adsorbed on the ethylatedβ-CD polymer were similar with those of the parentalβ-CD polymer, but theadsorption ratios of AAA on the ethylatedβ-CD polymer were higher than those of the parentalβ-CD polymer. It may be due to the strengthened hydrophobic interactions between AAA and the ethylatedβ-CD polymer, which was caused by the ethylation of the parentalβ-CD polymer.

研究表明其对芳香氨基酸的吸附规律与母体β-环糊精聚合物类似；与母体β-环糊精聚合物相比，芳香氨基酸在该聚合物上的吸附率有所增加，这可能是因为乙基化增强了β-环糊精空腔外沿的疏水性，从而增强了乙基化β-环糊精聚合物与芳香氨基酸之间的疏水相互作用。
