The products with x=0.5~2.0 at 100~500 ºC are P type semiconducting materials due to their positive values.
The Seebeck coefficients () are negative when x=0.1 at 100 ºC and 200 ºC, which indicates the samples are N-type semiconductor materials, while those are positive at 300~500 ºC, which indicates that the samples are P-type semiconductor materials.
The products with x=0.5~2.0 at 100~500 ºC are P-type semiconducting materials due to their positive values.

In such a grim situation, it is necessary to predict the corrosion behaviour of such lap joint structures with dissimilar materials by a method.
PARSTAT4000 electrochemical detector (Figure 2) is used to measure the polarization curve of electrode materials.
It can provide a lot of useful information in the corrosion mechanism, corrosion rate and corrosion sensitivity of specific materials in specified environment etc [5].
This makes it clear that the boundary element model can be used for specific service environments of different aircrafts to predict the galvanic corrosion of lap joint structure with dissimilar materials

So the fire caused by woody decoration materials would be more and more.
Materials and methods Prepare of the castor stalk powder Castor stalk is from Zibo city, Shandong province, China.
Because the first phase is the dry stage and the pyrogenation of the wood materials is begin from the second phase, so it only studied the relationships between the pyrogenation (the pyrogenation of wood materials in the second and third phase) and the chemical composite amount.
