The research on different types of water environment in protozoa community is important to research all kinds of lakes, rivers and water environmental pollution situation and self recovery ability. 1.1 The position of protozoa in the water ecological system The research on auatic plankton main in large rotifer and crustaceans, protozoa related material very few and very one-sided.
Protozoa in the role of water ecological system can be divided into two aspects: on the one hand, they through the food chain and surface absorption, directly energy conversion, make the macromolecular material from complex into simple compounds, can be in the water environment in the cycle.

Introduction Alumina is a ceramic material widely used in industrial applications at high temperatures.
The synthesis of nanocrystalline ceramic materials offers new opportunities for their developments.
Nanocrystalline materials are structurally characterized by a large volume of grain boundaries, which can significantly alter its physical, mechanical and chemical properties [2].
