The corrosion resistance was one of the key factors to determine service life.
Failure Factor Analysis Product Quality.
At present, the main work was to optimize or form the evaluation methods and acceptance requirements based on the key issues of tightness, dimensions, and collapse of pipes, mechanical properties and corrosion resistance of welded joints, and so forth. 5) It was suggested that design units, oil fields, manufacturers and relevant research departments worked together to screen corrosion factors, and clarify the scope of materials applicability further.

Introduction Phthalate esters (PAEs) represent a large family of chemicals most widely used as plasticizers, primarily in the production of polyvinyl chloride (PVC) resins, adhesives, and cellulose film coating to improve mechanical properties of the plastic resin, particularly flexibility [1].
The phenomenon can be explained that at low ozone concentration, ozone concentration is a control factors of oxidation reaction rate, and with the increase of the dosage, its influence was abate.
The pH value of the solution was another important parameter affecting the degradation of DEHP.
It was found that a few of factors, such as the concentration of oxidant, pH value of the solution and the initial concentration of DEHP had a significant effect on the degradation.

Community is a basic social unit involving residential building construction, inhabitant transportation, energy utilization and individual behavior which may significantly affect the human generated carbon emissions.
According to Report on the Environmental Benefits and Costs of Green Roof Technology for the City of Toronto [[]Information on http://www.toronto.ca/greenroofs/findings.htm ], green roof system has the following advantages: reduction in stormwater runoff that affects quality of local water resources; reduction in energy consumption; reduction in the urban heat island effect and associated cooling costs; beautification of the city; creation of more natural green spaces and opportunities for local food production.
Solar energy is attracting more attention in green building energy system due to its abundant and clean properties.
A variety of factors have to be taken into account to achieve multifunctional roles of BIPV system, such as photovoltaic module temperature, shading, installation angle and orientation.
Vol. 17 (2013), p. 54 ] also presented seven community wind cases in Oregon and identified common factors that should be considered by community for wind energy projects, including geographic features, land ownership, attitudes of the local residents, wheeling utilities, power buyer, county incentives, state incentives, federal incentives, other incentives, financing sources, developers, conservation groups and manufacturers.

So in the anchoring system, the interfacial properties between induration and soil should be regarded as the research focus.
It can be expressed as following: (1) Where, f is friction factor, and Q is confining pressure.
Therefore, the friction factor will change with the axial force and displacement.

However, autografts have two major drawbacks, donor site morbidity and unpredictable rates of resorption due to bio-mechanical factors.
The mechanical properties of the regenerated bone are also equivalent as shown quantitatively by Wheeler et al's studies using the Oonishi Model [24].
The positive findings of successful use of bioactive glass particulate alone in a graft site indicates that if there is a sufficient supply of blood then there will be a cascade of healing inductive factors such as TGF Beta delivered to the site, thereby eliminating the need for bone morphogenetic proteins and other inductive factors being released from an autogenous bone graft.
The trial's preliminary findings show zero post operative infection, zero loss of implants from migration or any other factors.

Modeling and Simulation of Two-way Quantitative Motor Synchronization System Based on AMESim Chen Yongqing1, a; Liu Pan1, b; Zhang Shaoqing1, c 1College of Mechanical & Material Engineering, China Three Gorges University, Yichang, 443002, China achenyq@126.com;bliupan198731@163.com;czhangsq1072@163.com Keywords: quantitative motor; synchronization system; simulation; AMESim Abstract.
There are two ways of controlling the synchronization of cylinders or motors: mechanical synchronization and hydraulic synchronization.
It is difficult to achieve precisely synchronization for the influence of various factors in the actual working conditions.
Friction, temperature, oil and gas property can be involved in you model if you need take those parameter into account.
Synchronization accuracy of system is affected by the following factors: 1) The machining precision of hydraulic motors and hydraulic actuators; 2) The load evenly; 3) The gas content of the hydraulic oil Synchronous actuators of the hydraulic system were constituted by several hydraulic motors and fluid cylinders which have high machining accuracy and the same size.

Surface roughness is used as the critical quality indicator for the machined surfaces and has influence on several properties such as wear resistance, fatigue strength, coefficient of friction, lubrication, wear rate and corrosion resistance of the machined parts (Feng and Wang, 2002).
The work of Davim and Figueira (2007), concerning the machinability evaluation of cold-work tool steel (D2) using statistical techniques, presented that the most influential factors for surface roughness are feed rate and cutting time, with percentage of contributions of 29.6% and 32.0%, respectively.
They also established surface roughness equations and demonstrated that surface finish is more directly affected by: in first term feed rate, secondly, tool’s nose radius, finally, by the cutting speed.
Singh and Rao (2007) predicted that the feed was the dominant factor determining the surface finish followed by nose radius and cutting velocity.

Destruction Form and Influencing Factors of Reinforced Concrete Column The destruction forms of RC column are mainly divided into bending damage, shear failure and bond damage under earthquake force.
Besides, according to the ductility, the damage forms are also divided into four types by hiro zawa masaya in the study of influence factors affecting column ductility.
According to the shear span ratio, yamada minorudivide the deformation properties and damage form of column into the ductile bending damage of long column (shear span ratio is equal or greater than 2) and brittle shear damage of short column (shear span ratio is lesser than 2).
Many factors, shear span ratio, stirrup ratio, reinforcement ratio, and axial ratio and so on, were considered, failure pattern of these specimens were eventually divided into bend damage, shear failure, bond cracking destruction and crushing bond cracking destruction.

Introduction Interstitial Free (IF) steel sheets, known for their excellent formability properties, have aroused attention in production and research of metallurgical industry since 1980's.
This is because that grain size distribution and texture development during recrystallization depended on two factors: nucleation and growth [10,11].
The mobility factor M exhibits exponential temperature dependence as it features the typical Arrhenius type behaviour of thermally activated phenomena [12].
So further grain growth can only affect the intensity of partial ODF, but almost can not change its texture character.
Summary Annealing temperature is the most important influence factor for grain growth and partial texture evolution.
