One of the most appreciated features of a great many of compounds of this class is an ability to change physical properties when being affected by a number of factors (e.g. resistance variation depending on application of certain substances).

Again, these parameters may be varied subject to synthesis conditions with a view to obtain materials with desirable properties [2].
Samples 1, 2, 3, 4 responded to ammonia, thus exhibiting their gas-sensitive properties.

Recent studies on cellulose extraction showed cellulose production of OFEFB is affected by various factors including pre-treatment of EFB [14, 15].
Among these factors, bleaching is a strong factor in determining the physical and mechanical properties of extracting cellulose.
This improves the mechanical properties of the cellulose fibre [21].
Other factors such as the origins of OPEFB and hydrolysis conditions also contribute to the yield of cellulose [22, 23].

Considering the diversity of traffic flow composition should be one of the major factors to find out the reason of traffic jam.
Numerical Simulation (1)Drivers are regular permutation In order to find how drivers’ characteristics affect the traffic flow properties, we further study the traffic flow theory under different drivers’ types condition.
Cars have different properties, drivers of each car also has different characteristics.
The more random of drivers’ properties, the more practical of the model.
In summary, the conclusions can be said that,(1)Driver s ’ property is a key factor that affects the dynamics of traffic flow.(2)The heterogeneous drivers model is more realistic and in accordance with real traffic flow, and also satisfies stable condition.(3)The drivers’ different characteristics are the factor causing the disturbance of traffic stream, and maybe one of the major factors of traffic jam.(4)Even the same type drivers, if they have different position. in traffic stream, may lead to different traffic vibration.

The surface roughness is affecting the detecting capacitance of MEMS device because surface to volume ratio is increasing rapidly.
Introduction Surface roughness plays important role in various electrical properties.
It can affect electrical properties such as electrical capacity, electronic conductivity, surface energy, critical area, peak electric field, surface tension, sheet resistance, etc.
Hence, the impacts of surface roughness on electrical properties of detecting capacitance with one smooth electrode and one rough electrode were investigated in this paper.
Image of height histogram and height percentage on the electrode sample The shape of the electrode perturbation is one of main factors affecting the capacitance values.

This degradation
of mechanical properties is a susceptible factor that affects the safety operation of facilities.
The effect of aging on the mechanical properties of each specimen was investigated using a tensile test and a fracture toughness test.
Then it was compared with mechanical properties from resistivities.
For evaluating the mechanical properties such as tensile strength and fracture toughness of aged material, standard specimens were used.
Relation between material properties Fig. 9.

Typical mechanical properties are Rm = 505 MPa, Rp0.2 = 435 MPa, elongation at break 13% and fatigue strength (limit) 150 MPa.
Therefore, an exact knowledge about FCG rates and various affecting factors is a very important basis for an assessment of residual fatigue life of structures and their in-service safety and reliability.
Since it was a material used for a Proficiency Test Programme (PTP) organized by Exova company for laboratories being involved in accredited testing for General Electric Aviation group, it had particularly homogeneous composition, mechanical and fatigue properties.
The only disadvantage was a very high price, but on the other hand, the characteristics affected reproducibility of experimental measurements very positively.
Though the alloy was homogenous concerning mechanical properties, it contained numerous areas with strong clusters of inclusions – Fig. 2.

The reason may be that the research on the mechanical properties of laminated glass with PVB film has not been conducted in domestic yet, which result in lacking of experimental data to support the material parameters, inaccurate understanding of the mechanical model of the laminated glass and corresponding numerical simulation,
The shear resisting is a main factor affected the performance of PVB film, and there hasn’t experimental research on the shear modulus in China yet.
As mentioned above, the shear performance of PVB is a crucial factor affected the performance of laminated glass, it is necessary to study the shear resistance of PVB film.
On the other hand, as we all know the main factor affected the bearing capacity of laminated glass is deflection under uniform loading.
