Introduction
Green attributes for office properties cover a wide scope of green characteristics that produce a high performance building in terms of resources and water efficiency, indoor environmental quality and building materials and low impact to environment.
This situation can be attributed to the fact that green office buildings are new, and as such, comparisons on the capital value and rate of return from these properties are limited.
Among the factors contributing to this difference is the combination of design and green features that comfortably blend with the environment.
This applies to the basic principles of investment, that cost reduction will directly affect the returns.

In recent years, the mechanical properties of TiN coating have been improved from several aspects.
In addition, there are many factors that influence coating performance, such as nitrogen flow, the target power, the negative bias plus on the matrix and so on.
The mechanical properties of the as-deposited coating displayed advanced hardness and modulus with the increased bias voltage.
And the mechanical properties included hardness, modulus and bonding strength was measured by a nano-indenter.
However, more particles will appear on the coating under exaggerated bias voltage and detects in the coating may increase, which affects the mechanical properties of the coating.

Introduction
During the launching and arresting of the shipborne aircraft, all the mechanical systems and equipments will bear the longitudinal and vertical over loading.
Of all the factors, the most important factors include pressure, pulsation and temperature of the oil in the pipelines.
As a result, the accessories can be affected.
Effect of the Flight State on the Performance Parameters of the Hydraulic System The flight state can affect not only the pressure and pulsation in the pipeline but also the working properties.
Therefore, the two conditions are the important factors which must be considered.

In recent years, due to its excellent mechanical properties, especially its insensitivity of strength to thickness, high-rise structural steel with high performance and heavy thickness made in china was applied more and more widely in large-span and high-rise steel building structures.
The high-rise structural steel was often used as H-section column with heavy thickness at present, and its residual stress distribution has significant influence on load-carrying capacity, which is one of the critical factors in reliability analysis of elementary members using high-rise structural steel.
The high-performance construction steel, represented by Q235GJ and Q345GJ steel series,are widely used in high-rise building constructions, showing superiorly good mechanical properties in seismic behavior, welding, stable yielding stresses and highly tear resistance.
However, relevant studies on the mechanical properties of the GJ series steel plate are far from enough, especially the exact prediction of the welding-induced residual stresses of the components, which will directly affect the design reliability analysis of structures.
Mathematic software MATLAB was used to accomplish this work.Fig.5 illustrates that variations of residual stresses through the thickness do exist in the heat affected zone around the welds.

Some theoretical models
to characterize mechanical properties are also reviewed.
Surface morphology including deposition, etching or mere roughening is the most frequently studied property as a factor affecting secondary stability [17-22].
The surface chemistry is also thought to affect the secondary stability independently of the surface topography, although it is difficult to separate the effects of these two factors.
Modeling of mechanical properties Hard and soft biological tissues are remarkable materials when regarding their ability to adapt the whole scale of external conditions by rapid changes of their physical properties.
The main method of characterizing mechanical properties of living tissues may be defined as follows.

The influence of both plasticizers on chemical, thermal and mechanical properties of the nanocomposites were investigated.
Tensile Properties.
The different in polarity between different types of plasticizer could be the main property that has influence on the differences in mechanical properties.

The fabrication is a key process for the preparation of ceramic tool materials, which governs the mechanical properties of ceramic tool materials under the condition of the same compositions.
The technology parameters, including fabrication temperature, pressure and duration time, affect the microstructure evolution and finally govern the mechanical properties of the ceramic tool materials under the condition of the same compositions.
Sintering temperature and duration time significantly affect the mechanical properties and microstructure of Si3N4 matrix ceramic tool materials [2].
The difference between fabrication parameters leads to the difference between mechanical properties of Al2O3/SiC [3].
The different fabrication temperatures can be chosen according to the properties of the initial powder and the expected mechanical properties of compact.

The paper shows the dose dependence carbon nanotubes for the physico-mechanical properties of cement mixes.
The formation of cracks in the cover/surface layer of concrete may affect permeability and presence of aggressive substances in concrete, these factors may then affect the life cycle of the structure.
Results of studies dealing with the effects of nanotubes on physico-mechanical properties are different.

Among the parameters, temperature was the most significant in affecting the interface morphology, followed by delay time, while injection velocity seemed to play no significant role.
The results were analyzed by taking account of rheological properties of the two feedstocks.
It was demonstrated the differences in the rheological properties of the metal feedstocks involved are key factors in determining the interface morphology of the molded parts.
The technological importance of the ability stems from its effect on various properties, and in particular on the mechanical behavior [6].
A good understanding of how and to what extent a molding parameter affects the interface morphology as well as its rheological reason is a prerequisite for controlling the morphology and properties of co-MIM parts.

For the objective evaluation of fabrics there are diverse ways in knitted fabrics, and the subjective evaluation of the fabrics involves not only basic mechanical properties, but also heat properties [4].
Surface properties.
The surface property is one of the important factors of hand feel which affect the touch warm-cool feeling.
The objective and subjective of warm-cool feeling In order to find the factors which affect the warm-cool feeling directly, we used the correlation analysis among the water absorption rate (WAR.), air permeability (AP.), moisture penetrability (MP.), surface properties, objective measurement and subjective evaluation.
The two evaluation ways get the different influence factors.
