Attempts at reducing κ have included increasing the phonon scattering by incorporating fine-grain size materials, and addition of a small quantity of nanophase [3].
In recent years, chemically stable particles were dispersed in thermoelectric materials for reaching an enhancement of ZT.

Some other suppliers of pyrotechnic raw materials have also put out many new products.
Preparation process of tested fireworks: desiccate and grind all the selected materials; select 90 mess of aluminum powder, sulfur powder and 60 mess of expanded pearlite powder; weight the materials according to the formula and mix them uniformly; mix barium nitrate with them according to the ration of 25:10:15:1. 1.3 Property characterization The modified barium nitrate morphology was observed with JEDL-6380LV scanning electricity mirror (SEM).

For this analysis, the orthotropic material properties are assumed.
Fig.12 Simplifing model of fixed-end beam under uniform pressure According to the mechanics of materials (Gere,2001), the maximal moment position of two-end-fixed beam under uniform pressure is the fixed-end, and its value can be derived as follows(Young,2002)

The chip segmentation is an important characteristic during the high speed cutting process of metal materials.
It is firmly believe that the shear localized chip can easily break,which contribute to chip disposal when machining metal materials.
