They have received extensive attentions of the researchers both home and abroad because of their high degradation efficiency, instrumental simplicity, and amenability to the environment.

因其处理效率高、操作简便、与环境兼容等优点引起了研究者的广泛关注。它能在常温常压下，通过放电反应直接或间接产生羟基自由基，紫外线和高能冲击波，从而有效降解难生化降解的污染物。

They contain one or more functional group such as amide, hydroxy, or carboxy.

它们含有一个或多个功能团如：氨基、羟基、羧基。

Low pH caused the amidogen of microorganism in the activated sludge protonized and high pH caused make the hydroxyl salinized, and increased the hydrolyzation of microorganism which would have side effect on the denatured effect.

过低的pH值会导致活性污泥中微生物氨基质子化；过高pH值会使之羟基盐化，而且过高或者过低的pH值还会增强微生物的水解作用，这样影响活性污泥的改性效果。

Two: Synthesized a novel rhodamine derivative with a single amidogen, then analyzed and characterized the dye by 1H NMR and EI-MS.
