Fig.1 The second boundary value problem in infinite plate Fig.2 Temperature curves in heating
surface and heat insulation surface
At the quasi-stable state,the temperature in plate central surface and heating surface were described as followed:
(4)
(5)
The temperature difference between the both side of the plate
(6)
If test the and ,coefficient of heat conductivity can be calculated:
(7)
Because,if test the temperature rise rate at quasi-stable state according to temperature increasing curves, then the thermal diffusivity of material can be calculated
When the transverse size is larger six times than the thickness of material, the temperature difference between test piece center and infinite plate can be ignored.

Its unidirectional nature, in conjunction with a
strong deformation textures typically seen in these materials, leads to a high level of plastic
anisotropy.
In situ neutron diffraction and acoustic emission have been used separately to study deformation twinning in various materials.

Methods and Materials: A photogrammetric system is composed of two cameras and one computer.
METHODS AND MATERIALS The principles of the technology are as follows: mounting two cameras to the ceiling of the treatment room; taking two plane images from different point of view; matching out the same markers of the two images and acquiring the three-dimensional (3D) surface models of breast; comparing the date with previously recorded reference surface model.

Considerable differences in hardness between the materials obtained from the two infiltration routes have been observed, with higher hardness numbers achieved with direct infiltration of green compacts.
Considerable differences in wear quality and friction coefficient between the materials obtained from the two infiltration routes have been observed, with higher wear quality numbers achieved with direct infiltration of green compacts.
Conclusions ü Infiltration of porous HSS skeleton with liquid copper has proved to be a suitable technique whereby fully dense HSS based materials are produced at low cost.

Potassium hydroxide and sodium hydroxide in concrete existed, they were also reactive material.
Tobermorite of cement hydration and secondary reaction was also reactive materials that reacted with carbon dioxide.
Although these materials carbonization properties were not different, the more these materials if these materials existed more in concrete , the slower carbonizing progress were.
