Materials of activated carbon (AC) were used as sorbents in FGD [2, 3] for high stability, large surface area, abundant micro-porous structure and surface oxide species.
Apart from calcium-based [6, 7] and carbon materials sorbents, supported oxide metals oxides such as Fe [8], Cu [9-10] and V [11] for catalytic oxidation SO2 into SO3 have attracted more and more interests of researchers and engineers, since desulfurization and regeneration reactions readily occur.

When it is rubbed with other materials, it shows low friction coefficient, and demonstrates its self-lubricating property.
MoS2 lubricant is uniformly distributed on the Ni60A alloy matrix material.
Ceramic material tends to be elastic contact.
The maximum tensile stress along the contact area is: (2) In the formula, u is the coefficient of friction, υis the poisson ratio of the ceramic materials.

The industrial degree of residential construction is limited, and its technology is low, while its consumptions of energy and raw materials are too much.
Especially, the clay brick, which is used in 80% wall materials, is highly energy-consuming material in production and destroys a lot of fields.
The study was arranged into the significant popularizing program of the National Construction Ministry in 2002, and the significant popularizing program of the National Science and Technology Ministry in 2003.
But with the development of science and technology, it can be said without doubt that the application prospect of multi-ribbed composite wall structure is very extensive.
