Many factors such as manufacturing technology of blade and erosion operating environment are considered to get more accurate results for service life of blade.
On the other hand, blade is also affected by corrosion.
At present, it is widely accepted that the design criteria, design guides or design codes used to evaluate the reliability of blade are limited, as they use the results of a simple deterministic analysis without considering the factors such as material properties and real operating environment.
Rao [3] developed various models to analyze the dynamic properties and stress of blade.
There are many factors contributing to the unsteady flow: nozzle wake, leakage flow, geometry variation of nozzle and so on.

Therefore, it is needed to investigate the return period and quantities of cores because these factors will directly affect the style and rhythm of production, and economic gains.
The practical way is to share the benefits and intellectual properties right via negotiation and comprise
These factors need to be highly considered when establishing evaluation models
However, the economic benefits are affected by many factors, even the disposal duty of cores.
These factors bring about great difficulties for operation of a production system.

Deposition of polyaniline/silica nanocomposite coating on stainless steel; study of its corrosion properties M.
These materials possess electrical conductivity, electronic and optical properties such as metals while retaining processability and mechanical properties usually associated whit conventional insulating polymers.
In the present case, the barrier properties are improved no doubt due to the nano-size of the PANI–SiO2.
The nano-size additives are known to improve the barrier properties of polymers for diffusion of solvent/gases by a factor of 10 or even higher[15].

In the technical indexes of the motor, motor steady state temperature is an important factor to influence the service life of the motor and the operation reliability, properly handle the relationship between motor steady state temperature rise and other properties, is the key to the success or failure of the development. 
The product of the project is based on long-term, comprehensive analysis of factors from the performance and influence, through testing to achieve optimal design.
Cold rolled steel sheet for punching and shearing stress sensitive, theoretically, punching after annealing treatment, can eliminate stress, restore good properties of cold rolled silicon steel sheet.
There are many factors are involved in the choice of groove, groove is beneficial to reduce some additional loss, but the noise of the motor may be affected, the project products combined with the calculation of electromagnetic noise of motor and the additional loss of the system analysis, and combined with the original product successful slot, has conducted the system research, part of the product has been adjusted, which makes it more reasonable[5,6].

Introduction Due to the human and natural factors, the stress balance of rock mass in the deep area is changed, which will lead to the elastic strain energy of rock is released.
And they got the mechanical properties of rock and damage models.
FENG X T [6, 7] analyzed the mechanical property of rock under the action of water by experiments.
Because these methods can reflect the mechanical properties of materials and get reliable results, this paper will use finite element method to analyze the mechanical properties of jointed rock.
Table 1 shows the mechanical parameters of model.

Because of the complexity of the process of LAM, the process parameters including laser process parameters and cutting process parameters are affected by a lot of factors, such as cutting speed v, feed rate f, cutting depth ap, laser power P, laser spot diameter, laser scanning speed, spot position, angle of incidence θ, and so on.
But the influence factors of real heating cutting temperature field are very complicated.
And all material thermal physical properties (such as specific heat, density, heat transfer guide coefficient and thermal diffusion coefficient) are constants not changing with temperature
The comprehensive evaluation factor of X33 is equal to 0.926.

The mechanical properties of the new material have been stated also.
On the basis of the physical mechanical properties of the polyurethane expanded material and its application in controlling the coal mine disaster, it is proposed that the material can be used to repair the building foundation cracked by ground fissures.
Still, other factors, such as surface water seepage, ground load and collapse of loess, can affect its movement.
In the 1970s and 1980s, most specialists accepted that ground fissures were a irresistible natural disaster, for its movement results from tectonic factor.
Excessive pumping ground water is a key factor of the movement of fissures. 2.

Malaysia is moving towards the sustainability approach and one of the key factors to achieve it is to reduce waste.
Most existing guidelines only highlights on the treatment process of contaminants which affects human health and environment.
Mechanical stabilisation is altering the physical nature of native soil by either vibration or compaction or by incorporating other physical properties such as barriers and nailing.
Thus, from the findings, these 3 main factors that causes problem had been identified which are transportation, storage, and treatment.
These are the factors which will lead to problems along the process of creating artificial land.

The shape of the object also affects its handling properties [19].
According to Yuan and Kuo [19], ball shaped objects have better handling properties compared to oval shaped and cylindrical shaped objects because ball shaped objects provide natural handling properties for the human hand.
Sometimes, a change in biomechanical factors such as pinch techniques, pinch width and wrist angles, can affect pinch strength [21].

Most importantly, the transparency and resistivity properties of the DLC films can be tailored to approaching diamond by adjusting substrates bias and volume C2H2, is important to many applications, which is improve film properties.
Which are important factors that can determine these properties to be suitable for applications in various forms Depending on the process of film synthesis and many elements that come as variables.
Therefore, in this paper, the study of the transmission properties and electrical properties of DLC film using the film synthesis process with ECR-CVD system with different conditions.
Theory Optical transmission properties use the T92+(pg instrument) as a dual beam type machine.
