Experimental Materials and Methods.
The Fe-C material was prepared by the mixing of iron filings and activated carbon according to a certain proportion, and the iron filings were firstly soaked in alkali lye at 80 °C for 30min, removing grease substances of iron surface, and then soaked with dilute sulfuric acid, washing rust and grease thoroughly, and achieving the activation of elemental iron.
Therefore, the pH of acidification demulsion was selected about 3.5 from the perspective of saving the test material.

These results show that: the filling material, cementation and closed state play an important role.
It not only represents rock block size of rock mass, but also is the material foundation of rock mass structure [5].
To attach importance to material composition is precondition which reveal the unique characteristics of various objects.
The studies of rock mass structure, rock mass quality grade and rock mass mechanics parameters will break away from its basis, without considering the material composition or lithology and the influence of rock strength and stiffness.

Wind turbine is composed of the wind turbine and generator, wind turbine blade is the core of the most critical part, at present, the main material for the blades is glass fiber cloth [2].
During the campaign, the ants will release a substance called pheromone on the path [11], and can sense the existence and strength of this material, and wove toward the place where pheromone is strength, to guide the direction of movement.

In 2007,the units of hunan province like Hunan University, Hunan Provincial Architectural Design Institute and Earthquake Administration of Hunan Province did the research on the anti-seismic performance of buidings in Yiyang and Huaihua, Xiangxi etc..All the results showed that the bricking-up structure account for the investigation of the total number more than 80%, and mainly for row-lock cavity walls .However,the rowlock cavity walls had many problems, for example the buildings to be lack of direction,without seismic tectonic measures;poor quality construction material;site selection undeserved, low level construction, which make the buildings have poor seismic behavior .
Brief Introduction about High Performance Ferrocement Laminate The new inorganic material--Composite Mortar developed by Hunan University is different from normal cement mortar for its adding additive ,such as polypropylene fibre, ettringite type expansive agent, water-reducing admixture, and wollastonite, fly ash, etc .It not only has the very high tensile strength,(3 ~ 5MPa), compressive strength( above 40MPa) , good bond strength, toughness, ductility and larger ultimate tensile strain, but also its environmental protection, convenient construction , less influence of original structure size etc, wnhich make it the favour of reinforcement industry at home and abroad .
In this experiment we designed eight specimens with three laying methods (all-rowlock wall, three steeps a sleep wall , a steep a sleep wall ),size of test for wall 2050 x 15 x 240, and ratio of high to width is 0.73(with the average compressive stress0.15 MPa).The materials for construction include clay solid brick MU10 and bonding mortar M1.0.The connection points at roof( bottom) concrete beam and wall there was 10mm thick mortar laying, applied for the power transmission and fixed,as is shown in Figure 1.

It is considered a strong carcinogen [5, 6] and is emitted into the air during incomplete combustion of fossil fuels and other organic materials (e.g., during processing of coal, petroleum and oil; natural gas combustion; waste incineration; operation of motor vehicles, etc.) [6].
The incomplete combustion of organic materials can produce different amounts of BaP.

Its development not only reflects the development of measurement theory itself, but also embodies the earnest attitude of researchers on science, their requirements for the accuracy and the urge to improve it (Fig 1)[2].
Through large amount of observation, the students can seek experience as a reference, which will be of great help for understanding how to use different shapes, materials and colors in different kind of constructions.
Therefore, the evaluation method of the efficacy based on reasoning can provide a favorable method and guidance to evaluate space and teaching and the students can collect abundant evidence and useful materials to evaluate the optimal architecture for the people in accordance to the design specifications.
