The direct extrusion process using the mechanically alloyed powder as raw materials was applied to prepare the thermoelectric materials.
But, the Z value in randomly orientated p-type material is about 6% less than highly oriented materials [1,4].
The doping method has often been applied to improve the Z value of the thermoelectric materials.

Study on the Environmental Materials with the Emergency Rescue Procedures for Water Pollution Accidents Caused by Benzene Series Fire Yuanyuan Wang Kunming Fire-fighting Command School of public security fire forces, China wyuanking@tom.com Keywords: benzene series fire; environmental materials; water pollution accidents; emergency procedures Abstract.
Benzene series are important petrochemical materials, which are mainly used in the industry of pesticides production, dyes and explosives manufacturing.
In the process of extinguishment, 5000 tons of water and 28 tons of foam were consumed, because no effective measures are taken timely after the explosion, part of the leaked materials, the circulating water and the mixture of fire water at present and residual materials are discharged into the Songhua River.

After more than half a century of development, there are dozens of already forming method of composite materials.
So the improvement of the process becomes the key to development process of advanced composite materials, the next step.
Raw materials also realizes diversification, the properties of the products can be designed.
