Since the aldehyde groups can be reversibly converted into enol groups depending on acidity and alkalescence of environment, the inter-and intra-molecule interaction of CMDA can be adjusted by changing the pH of medium, as a result, the self-assembly behavior of CMDA may be altered.

结果表明，CMDA在水中自组装形成纳米自聚集体，在pH=4.0和pH=10.83溶液中CMDA的临界聚集量浓度值分别为0.002mg／mL和0.005mg／mL，比中性环境中的临界聚集量浓度（0.02mg／mL）低了1个数量级。3种pH条件下自聚集体溶液表面张力具有共同的变化趋势，但在酸性与碱性条件下具有更好的表面活性。

In the pelagic subsystem,there are 4biological state variables which were represented by functional groups:flagellate,diatom,pelagic bacteria and zooplankton.In the benthic subsystem,there were 5 biological state variables represented also by functional groups:macrobenthos,meiobenthos,aerobic and anaerobic bacteria,and shrimp-which is actually epibenthos.

将浮游亚生态系又划分为4个功能群，分别为：鞭毛藻、浮游硅藻、水体中细菌和浮游动物，将底栖亚生态系划分为5个功能群，分别为大型底栖动物、小型底栖动物、底栖厌氧菌、底栖好氧菌，对于营底上生活的对虾也划分在这一亚生态系中予以考虑。

Methods Thirty domestic dogs were randomly divided into 5 groups (6 in each group ): model control group, positive control group, and TGP groups with doses of 2.0, 4.0, and 8.0 mg·kg-1, respectively.
