Introduction Nowadays, the nanocrystalline zinc ferrite (ZnFe2O4) attracts great interest as microwave dielectric materials.
All this materials were weight analytically in stoichiometric proportions and dissolved into deionized water with citric acid as chelating agent.
SiO2 material which has high energy band gap mixed with composite semiconductor material relatively has low energy band gap and this will produced new energy band gap that will located between this two semiconductor materials [24].

At the present time, there are a few bilingual teaching materials of AMT, and teachers can choose bilingual teaching materials of AMT by the situations of students, or to write bilingual teaching materials by referring the materials both at home and abroad.
We should choose those teaching materials which have moderate difficulty.
Some AMT teaching of universities abroad are successful, and the teaching materials are good, however it’s too hard to Chinese students, so we can’t just use the original edition teaching materials from abroad, but to choose and adapt those materials when we are using original edition teaching materials.
To use idiomatic English is another rule to write or to choose bilingual teaching materials.

Adhesion and Corrosion Resistance Properties of TiC/Ti(CN)/TiN Multilayer CVD Coatings on 42CrMo Steels Zhang Jin a ,Xue Qib ,Cheng Xiaoweic ,Zhang Chunmeid ,Li Songxia e school of Materials Science & Engineering, Southwest Petroleum University Chengdu 610500 P.R.China a jzhang@swpu.edu.cn, b qxue01@163.com, ccxw0261@sina.com, d zcm_331@163.com, e lisongxiay@163.com Keywords:TiC/Ti(CN)/TiN multilayer coatings;CVD;corrosion behavior;adhesion Abstract.
There are in general two ways of improving the corrosion resistance of the steels.One way is to use Ni,Cr alloy etc,having better corrosion resistance to supplanted classes of engineering materials.However, the high cost of the mental prohibits its widespread use[1] .The other is to enhance the surface properties of the steels.Most steel failures due to corrosion are known to be initiated at the surface.The advantage to the coatings is that the substrate can be optimized for properties.Different types of coatings have found different engineering application.Ti based hard coatings(TiN,TiC,Ti(CN)) obtained by chemical vapor deposition(CVD) are attractive materials due to its high hardness,good wear resistance,chemical stability [2] .
