Gong [3] established the hierarchy structure assessment model and got the weight of every index based on expert system.
Fig. 1 The Comprehensive Environmental Assessment Model According to the Society for Environmental Toxicology and Chemistry (SETAC), LCA is typically divided into four steps: goal and scope definition, inventory analysis, impact analysis and improvement assessment.
With consideration of the low level of recycling and reusing construction solid waste in China at present, this study assumes that all demolished masonry structure compositions become solid wastes without any recycle or reuse except reinforcing steels, which can be completely recycled, resulting that the total volume of solid wastes can be thought to be equivalent with that of masonry blocks and mortars.

An analytic method is proposed to research the sensitivity problem of spindle platform structure parameters and the sensitivity model of a type of parallel platform/robot is built in [18].

The nature of photocatalysis is based on solid state chemistry and knowledge on crystal structure, imperfections in solid, nonstoichiometric as well as electronic properties of solids for characterization of photocatalytic materials.
TiO2 has three polymorph forms varying in crystal structures as rutile, brookite and anatase.

The effect of relevant structural factors, such as powder particle size, chemistry, heat treatment conditions was quantitatively analyzed for different powder heats.
Consequently, such a microstructure can offer a better compromise with a relatively higher cyclic hardening and a longer fatigue life with the occurrence of highly tangled dislocations followed by the formation of a vein-like structure.
Transgranular crack propagation in twinned structures has also been observed (Fig. 4b).

It has been rapidly developed in recent decades and widely used in analytical chemistry field [2,3], such as solid phase extraction, membrane separation, solid phase microextraction, stir bar sorptive extraction and chemical sensors.
It had a porous structure with a skin layer, under which was followed by a finger-like structure.

To overcome this obstacle, numerous attempts have been made to alter the surface chemistry of carbon black particles and improve their dispersibility in aqueous solution, in particular, simultaneously enhance their compatibility in the polymeric matrix [8, 9].
