The bran and straw has good insulation properties, laying these biomass materials on the ceiling could achieve insulation.
If mix ash, wheat bran and other insulation materials in the mud back, add the local rich straw woven grass mat in structural layer, can greatly improve the roof insulation effect.
For this, there are two improved methods, one is adding 120 mm protective layer on the original wall, and reserving 50mm hollow layer between the two insulating layers, and the hollow layer can be added raw materials or polystyrene board, etc. which have a small thermal conductivity, can also be set to air layer.
Biogas is one kind of clean energy which take manure, crop stalks as raw material, produced by fermentation in a certain temperature, mainly for cooking, lighting and so on.

In case of that the materials have large difference in melting temperature, formation of intermetallic phase could be controlled by using solid state -liquid state reaction at the interface [4].
However, in case of magnesium alloy / aluminum alloy dissimilar metals welding, melting point for each materials are very closed, then the solid state -liquid state reaction can not be realized.

Although this theory is a classic theory of removal in glass polishing, it is also appropriate to the finishing process of most metal materials to a great extend [3].
To find out the optimum factors for various materials and figures may be a important task in further aim of our research.
Conclusions SFA finishing technique is effective in the finishing of revolved surface, and is suitable for a variety of work piece shapes and materials.

Preparation of the Al2O3/3Y-TZP ceramics by microwave sintering under low temperature Junming Luo 1,a, Jilin Xu1,b ,Hongyan Zuo1,c, and Jun Huang1,d 1School of Materials Science and Engineering, Nanchang Hangkong University, Nanchang China aljmniat@126.com, bjlxu@nchu.edu.cn, chyzuo@nchu.edu.cn and dhuangjun@nchu.edu.cn Keywords: Coprecipitation process, Al2O3/3Y-TZP, Microwave sintering, Nanometer powders Abstract.
Introduction Y-TZP ceramics, as one of the best comprehensive properties of zirconia materials, have been widely applied in the fields of chemical engineering, machinery, communication and aerospace [1].
At the same time, the Y-TZP ceramics show relative low the strength and roughness and low temperature properties, which seriously limits the further application of the materials [3-5].
Therefore, the microwave sintering possesses the advantages of low sintering temperature and short holding time, which is beneficial to obtain the fine grains and improve the strength, plasticity and roughness of the ceramic materials [9].
