The active sludge method complete mixing type and stage aeration combination process possesses stronger anti-strike performance, higher removing ratio of organic compound etc.

活性污泥法完全混和式和阶段曝气组合工艺，具有抗冲击能力强，有机物去除率高等特点。

So far there is no complete theory to describe the process of ion-beam mixing and the investigation of the mechanism on ion beam mixing is still largely lacking.

但是，对其物理机理的研究还很不够，还没有一个完整的理论可以描述“离子混合”的过程。
