However, building energy efficiency is not only relevant to architectural and physical properties of building, such as thermal mass, structural material, and its shape, but also local climate [1].
This will make the insulation properties of insulation materials worse and even failure.
For interior thermal insulation wall, because its insulation layer is located in the interior, its insulation layer will not be affected by the wind pressure.
To ensure good thermal insulation properties, weather resistance, durability and resistance to impact, the exterior thermal insulation system are more demanding in the raw materials (e.g., the demand for alkali glass fiber mesh cloth, the crack resistance requirements of the mortar, etc.) and the construction technology than the interior thermal insulation system.
For the upward factor, interior thermal insulation system is more suitable in south China.

As for the prominent state of abrasive grain, after the truing of the grinding wheel surface, is not only influenced by the wear volume but also affected by the truing parameters.
Therefore, in this paper both orthogonal test and single factor test method are used to study the effect of truing parameters on the truing quality of grinding wheel.
Table 3 Evaluation parameters of microscopic 3D roughness of the grinding wheel Parameters Mathematical expression Property Sp Sp=Max[Z ( x, y )] Evaluation of the maximum protrusion height of abrasive grains: The larger the Sp value, the greater the maximum protrusion height of the abrasive grain.
To address the problem above, this paper carries out the single factor experiment of feed and the results of the three-dimensional roughness of the surface of the diamond grinding wheel are shown in Table 5.

The one-stage loading composite slab is similar with the cast-in-place slab in mechanical behavior.
Mechanical behavior of smooth surfaces, indentation surfaces and binding reinforcements were researched by Hou Jianguo [5].
In addition, edge joints between the precast bottom panels may affect the integrity of composite slabs.
The roughness of bottom panel surface can affect the bond force of composite slabs.
Additionally, the edge joint detail is main factor in crack resistance and integrity for composite slabs.

Mechanical components, used in automotive, aerospace, naval structures, nuclear plants etc, are subjected to unsymmetrical loadings, with a mean stress different from zero.
Therefore, fatigue life and fatigue limit are assumed to be controlled by crack propagation law and threshold stress intensity factor, respectively.

The thermo-mechanical reaction during machining plays an important role in defining machinability of titanium alloys.
The scientific community is concerned about machining of titanium alloy due to problems occurring in the shear zone that affect tool life.
Titanium is considered to be a super alloy because of its unique properties such has high strength to weight ratio, good resistance to corrosive environments and high load bearing capacity [2].
While capturing, a ruler is placed near to tool holder to determine the scale factor in order to calculate the length and angle of regular geometric projections in the image.

Introduction Polycarbonate aging can cause not only appearance, physical properties, mechanical properties, electrical properties of polycarbonate degradation failure, and the produced bisphenol A which is a kind of endocrine disruptors can disrupte endocrine, affect the healthy development of embryos and have an impact on infant development and immunity, cause sexual precocious, even carcinogenic [1].
Since oxygen mainly affects the surface of the polymer, the degradation of the polymer is mainly in the initial stage of degradation.
Under the high temperature thermal stability properties of polycarbonate.
So under the conditions of no other factors, the high temperature will cause the degradation of polycarbonate molecular chain rupture.

The mechanical properties of the fabricated scaffolds were assessed and compared to the designed porous architectures.
The scan speed is also an important factor in the sintering process.
In the processing laser didn’t affect the component of the two powders.

Although there have been no MSD attributed accidents in the last twenty years, there is, however, a serious concern that MSD could occur again in the commercial aircraft fleet and it could potentially affect any ageing aeroplane in service.
Mechanical properties of AA 2524 are: young’s modulus 70GPa, yield strength 332 MPa, ultimate strength 463 MPa.
The curves of crack growth rate da/dN vs. stress intensity factor (SIF) range ΔK of the seven specimens are shown in Fig.1.

This paper discusses the mechanisms of synthesis of advanced materials developed by SHS , their microstructures and properties.
The purity of inert gas and solid reactants, the completeness of degasification process, and an inertness of container's material affect significantly the oxygen content in the final product.
The traditional sintering of nonoxide ceramics is still a major cost factor.
Similar experiments of in situ uniaxial densification of combustion synthesized TiAl in a mechanical press were also performed.

Technically, they are mechanical cable entry devices.
Similarly, an insufficient function is performed by lock nut over the junction box where it holds/pushes it changing the surface area as property.
Contradiction, in TRIZ, happens when solving one improving parameter or characteristic of a technique negatively affects the same or other characteristics or parameter of the characteristics.
