However, for different parts, the processes in modeling operation and in analysis step selection are greatly different, which affect the accuracy and quality of parametric design.
Parametric design is a kind of modeling approach, which is based on a series of factors, including features, dimensional constraints, data correlation, and dimension-driving model.
For the parametric analysis of a part, initially parameters of the part have to be extracted in terms of its structural characteristics, mechanical properties, and engineering features.
In summary, through the simplification of workflow in design and analysis, as well as the improvement of work efficiency of designers, this technology builds a design platform for modern mechanical design and achieves the sharing of resource and technology.

In this paper, three types of faults have been considered, fault in the fuel flow rate, fault in the performance of turbine which affects the turbine exit gas temperature, and fault in the turbine which affects the turbine output torque.
In particular, three fault cases have been considered, namely: · Fault Type 1: Fault in the fuel flow rate, (fuel control valve fault ), f1(t); · Fault Type 2: Turbine damage (which affects the turbine exit temperature), f2(t); · Fault Type 3: Turbine damage (which affects the turbine output torque), f3(t).
However, this is still considerably longer than the duration of the GT dynamics which occur over periods of seconds, a factor which must be taken account of in any FDI algorithm design.
If the residual set can isolate all faults, it can be said that the residual set has the required isolation property [5].

Liquids and solids have better thermal conduction properties than gases.
Every insulation material has different thermal properties and characteristics, and each behaves depending on the compound.
The main factor in the design variables is roof orientation [18].

In the early years of research on nanocrystalline structures, materials were often available only in small quantities, insufficient to measure their mechanical properties by tensile testing.
At the same time the coefficient of friction dropped by a factor of 2.
This is more or less the same what is observed for nanocrystalline electroforms: the same properties are either not strongly affected by grain size or show considerable changes when the microstructure is refined.
It has been shown that several properties (e.g. the Young's modulus, thermal expansion and saturation magnetization) are not strongly affected by the presence of high concentrations of these defects.

The objective of this study is to investigate the factors that affect the burr formation to provide a further understanding of its mechanism using finite element method.
The rate of heat generated due to friction is given by the formula: ζrfrvFQ =& (3) where frF is the friction force, rv is the relative sliding velocity between tool and chip, and ζ is the mechanical equivalent of heat.
This is because of the difference in the properties of the workpiece material.

With the development of friction surfacing, it is necessary to obtain a thorough understanding of friction surfacing, such as the sophisticated thermo-mechanical behaviors, because they are the inner factors that determine whether the process could be complemented successfully, which affects the coating's quality.
In this paper, the finite element method was employed to study the coating rod's thermo-mechanical behaviors.
Thermo-Mechanical Process Analysis The whole friction surfacing process is divided into two sequential phases: the preliminary friction preheating phase and the next steady surfacing phase.
In this coupled thermo-mechanical problem, the temperature filed analysis is a matter of unsteady heat exchange with inner heat source.
The fundamental equation of the heat condition with changeable thermal properties can be expressed as the following 3-D, unsteady equation: 2 2 2 2 1 T T T T c k q t r r r z ρ   ∂ ∂ ∂ ∂ = + + +   ∂ ∂ ∂ ∂   & (1) Whereρ,c and k are density, specific heat, and thermal conductivity of the coating rod material, respectively,q& is the internal energy rate.

The coal seam is not affected by mining.
The factors that afect coal permeability’s change can be divided into two categories [7]: One is the thermodynamic parameters of coal seam methane, in this fact coal seam gas pressure is most important, some experiments shows that when gas pressure P <1 MPa is strictly klinkenberg effect, with the declining of gas pressure, coal permeability increasing. 
The second is the change of skeleton structure of coal, once the coal skeleton changes, the permeability of the coal seam will have a significant change After drilling in the coal seam, regeneration stress arising from Re-distribution of stress around the drilling,and the regeneration stress affect the permeability of coal directly. 
Figure 1 Gas flow of borehole,coal seam permeability coefficient (two algorithms) curve The eighth day , permeability coefficient drop suddenly may be due to gas emission from the coal seam which is outside distressed zone, it is no longer affected by pressure relief so the permeability coefficient is low. after the ninth day the permeability coefficient is low and in a small range to keep floating up and down no longer have a big change, this may be because the gas pressure and skeleton structure of coal outside the pressure relief area unchanged, so significant change of the permeability will not happen, but it is not a constant value also,it floating up and down in a small range . may be coal permeability around the drilling is controled by space, time, secondary stress, gas pressure and coal physical and mechanical properties , is a variable, can not be steady.It floating in a stable and small range ,this stable range may be the original coal seam permeability coefficient.

CO2 corrosion mechanism is complex which can be affected by a number of factors such as pH, temperature, flow rate and CO2 pressure [5-7].
From Fig. 3 it also appears that the cathodic reaction was affected by the change in CO2 pressure, while the anodic reaction was not affected [13].

Notably, the IMCs (intermetallic compounds) formed during the solder joining duration and its vibration resistance affected the reliability.
To obtain steady properties for comparison, some of the specimens were subjected to stabilization treatment at 120� for different duration followed by air cooling to room temperature.
Reportedly [9, 5-7], the lamellar-deformed structures (LDS) of proeutectic Sn-rich phase also affect the damping capacity.
Both lamellar-deformed structures (LDS) were the main factors in the vibration crack propagation mechanism. 4.
