It is important to include the factor of coupling agent, when making predictions the properties of the composites through the models.
The low compatibility and interfacial adhesion of such composites results into low mechanical and thermal properties of the final products [5], [6], [7].
Background Wood Plastic Composite (WPC) properties depend upon many factors such as strength of wood fibers, modulus of fibers, fiber length and diameter, fiber weight percent, fiber orientation [8]-[11].
However, studies made on composites suggest that coupling agent is also a crucial factor to obtain better composite properties.

Under the premise of the fabric can play a role in waterproof, permeability is a key factor affecting the wearing comfort of human body.
There are Many factors that Waterproof and breathable performance will be affected for the waterproof and breathable coating fabric.The fabric type and density, the ratio of pulp and additives, and coating process control is the most important factor.
The role of surface coating processing is to give good mechanical strength, wear-resisting property, scrub resistance and other apparent performance.
The surface coating processing should have high mechanical strength, good wear resistance properties.

In all of environmental factors the temperature is one major factor, the high precision measurement should be conducted under homothermal condition; the temperature and the humidity should be remained in allowable bands depended on the measurement accuracy; the measurement should not be conducted until both the measured quantity and the measuring implement reach the standard temperatures. 2 Error Analysis 0f 0n-line Measurement System The image on-line measurement system mainly is composed of lighting system, measured parts, optical imaging system, image pick-up devices and computing group, Analysis of Inner and outside Environmental and Equipment Materials, the factors affecting the system accuracy mainly include lighting system, optical imaging system, CCD pick-up devices, image collecting card and software algorithm.
In this section, we mainly analyze these factors and the corresponding errors.

Generally, the main influence factors of the stability of surrounding rock mass are geological structure, in situ stress, the mechanical properties of rock mass, scale and buried depth of power house, the order of excavation and support scheme.
Displacement and Stress Field Impacted by the Mechanical Properties of F211 In order to study the displacement field and stress field impacted by the mechanical properties of f211, the computational scheme to reduce the parameters of f211 as lower value in Table 1 is considered.
Displacement and Stress Field Impacted by The Mechanical Properties of Quartzite In order to study the excavation displacement field and stress field impacted by the mechanical properties of quartzite, the simulation analysis were carried out by increasing the mechanical properties of quartzite rock mass to II species rock mass or reducing that to IV1 species.
Conclusions From the research and analysis work described above, the summary can be obtained for the Yantan extended hydropower project: (1) The mechanical properties of fault f211 are weaker relatively.
The mechanical properties of quartzite is better relatively, its relative location to the power house has no obvious influence to the stability of the power house.

Die-cast Magsimal-59 has excellent mechanical properties when the cast product is thin, as the mechanical properties of Mgsimal-59 depend on the thickness of the cast product.
The mechanical properties of the specimens were investigated by tension testing.
These mechanical properties are very poor.
This means that the effect of the cooling ratio on the mechanical properties is very large and the mechanical properties of the Al–4.8%Mg–2%Si are very sensitive to the cooling rate.
In the casting of the Al–4.8%Mg–2%Si, the size of the ingot appears to have been the dominant factor determining its mechanical properties.

Investigations show that, mechanical properties and engineering performance of LVL are affected by many factors such as wood species, veneer thickness and quality, processing variables, member size, in service environment and loading types [1,2,3,4,5].
And each of the factors had eleven testing levels.
So the neural network model can be used to predict the valuable mechanical properties of LVL.
But the results from the neural network model in this study show promising potential for simulating complex nonlinear function approximations between production technology factors and the mechanical properties of LVL.
It is therefore feasible to develop robust ANN models to predict mechanical properties of LVL.
