In this thesis, a new method to determine the electroosmotic mobility in CE based on wavelet transform was developed.

本文首先建立了一种基于小波变换的毛细管电泳电渗流淌度测定新方法。

The results show that the electroosmotic flow gradually reduced with increasing PAMAM generation.

结果表明，随着大分子代数的增加，毛细管电渗流逐步下降。

The addition of 0.2 mmol/L of cetyltrimethylammonium bromide could change the direction of electroosmotic flow.

由于在背景电解质中加入了0.2 mmol／L十六烷基三甲基溴化铵，因而电渗流的方向与传统的毛细管区带电泳中电渗流的方向相反。

Also, the equation may be used for the estimation of electroosmotic mobility and the calculation of the dissociation constants for acids.

不仅如此，我们还通过文献实验和我们自己的实验验证了我们的新方法，另一方面我们还证明了毛细管电泳测定酸的离解常数的可行性。
