More detailed way to classify the double skin facades according to the (Figure 1, 2) [5, 6]: - type of ventilation: natural; enhanced by ventilator; mechanical
- airflow direction: to the top or to the bottom (only in case of mechanical ventilation)
In the cold season exterior vents are closed to allow heat to build up in the cavity spaces, which protects against cold winds while improving the thermal insulating properties of the windows by as 20%.
Together, all those physical factors condition the design of a double skin façade, and must be respected and followed in order to achieve improved comfort of the internal environment and reduce energy consumption.

The actuator property is the key-point factor for the valve property and choosing high quality actuator is very important.
Both of these properties benefit for expanding valve working range.
So, it's necessary to research on the jet valve dynamic properties.

Mechanical properties of GMM are affected by mechanical environment and electromagnetic field.

The water-cut growth is caused by the following factors: low initial hydrocarbon saturation of reservoirs, high phase water permeability, irregularity of reservoirs by section and lateral caused by low filtration resistance in the pay horizon of superconducting channels.
Field and laboratory experience shows that preserving reservoir properties of the formation and the limit oil recovery factor without using special oil displacement agents can be reached when water is injected into the formation whose composition is similar to produced water (Cenomanian water).
Using OSECs is efficient for affecting clay reservoirs, reservoirs with zonal irregularity of the formation and high-temperature formations.
To preserve the porosity and permeability properties of the formation in well killing, complex compositions are recommended that contain clay swelling inhibitors.
Where water is injected, its efficiency is insufficient for maximum oil displacement since the reservoir has low permeability and porosity properties.

The shearer drum is the operation mechanism, its design will directly affect the coal mining machine's life and the enterprise economic effectiveness. physical and mechanical properties diversity of coal lead to the drum design diversity drum ,the drum design must follow the "tailored" design principle.
For each cylinder in the helix angle, lead, inside and outside diameter, the intercept and installation of components gap shape cutter are the same, the different components of that gap on the location of cutter; the difference between different drum roller intercept, both inside and outside diameter of the leaf and the side plate shape and other factors.
Based on the principle of functional design from the perspective of the analysis of the drum, combined with product appearance, function groups, manufacturing and many other factors on the drum break it down, combined, will eventually be divided into a series of roller base module, the module by the matrix shown in Fig.3 shows, the drum exploded basic modules.

Although epoxy-bonded steel plate reinforcement has been applied in practice home and abroad for more than 30 years, most of researches focus on the mechanical property and structure of this reinforcement method[2]-[5]and seldom on quality inspection of epoxy-bonded steel plate reinforcement.
In order to realize standardized inspection, mesh for detection is a reasonable method, but in practice a lot of factors have to be considered for determining the mesh size: (1) the constraints on mesh quantity when acceptance rate of bonding area is 95%; (2) balancing between inspection workload and accuracy; (3) limit on hammer size.

Due to the difference of thermal properties between non-defective part and defective (damaged) part, the temperature variation of a structure caused and generated by air temperature and sunlight or artificial heating or cooling appears as surface temperature difference.
Many factors such as season, region and climate (cloud, fog) can affect sunlight intensity.

Among them, the functional parameters of surface roughness, such as Sbi, Sci, and Svi, are used to evaluate bearing and fluid retention properties of surfaces.
A good surface roughness can improve tribological properties, corrosion resistance, fatigue strength, and esthetic appeal of the product [2].
Among them, functional parameters of surface roughness are effective in characterizing functional properties of surfaces, especially bearing property and fluid retention property [3].
The network structures, especially number of neurons and layers in the hidden layer, are very important factors that determine the functionality and generalization capability of the network [7].

Introduction When rolled heavy rail is on the cooling bed for natural cooling, its bending deformation caused by solid phase changing and the section sizes contraction deformation occurs, there are many factors affecting cooled rail deformation, such as the initial cooling temperature, environment temperature and cooling velocity.
Cooling velocity can be controlled easily in the producing process, the air flow speed around rail is the main factor affecting cooling velocity, that can be measured in convective heat transfer coefficient [1].
Flashline TM-5000 Thermal Properties Analyzer which is produced by Anter company in United States is applied to measure U75V heavy rail specific heat capacity and the coefficient of thermal conductivity.

According to materials design principles[2], adding strengthening phase (particle or fibers) to the matrix can improve the toughness, strength, wear resistance, and creep resistance properties of composite material.
So, the sintering temperature, affecting the generation process of the fiber by many methods, is one of the important factors determining the fibers’ characteristics.As a special crystal growth process, the fibers should also experience the nucleation and growth processes.
Under certain circumstances in the system, the equilibrium temperature directly affects the size of the diameter of the fiber, and the elevated temperatures decrease of the degree supersaturating so that the fiber diameter increase, And vice versa.

In addition, the nuclear reaction process between the incident particles and materials can produce transmutation atoms and spallation products such as helium atoms in materials, which can affect the microstructural evaluation and mechanical properties of the material [13].
