It has affected the quality of the signal transmission line, resulting in circuit performance and reliability of electronic system decreasing.
The victim network and interfered network will both be affected each other when coupling occurs.
Some of the parameters which are inherent properties of materials usually unchanged.
The reason is that when the impedance of microstrip deviates from the standard impedance and increases from 25Ω to 100Ω,the width becomes narrower, the insertion loss and the reflection gradually become larger, so the electrical properties becomes worse.
Analyzing the affection of coupling loss to the signal transmission performance When signal transports in the microstrip, in addition to its own conductor loss and dielectric loss, the adjacent transmission lines have energy loss caused by the coupling affecting the signal transmission performance.

Introduction Recently, the applications of nano materials were spotlighted by many researchers because of unique and exceptional characters of nano materials such as photo-catalytic, electronic, magnetic and mechanical behavior, etc.
The main factors to affect the mechanical properties of compacted materials are the microstructure and the pores in the compacts.

Based on the fatigue damage mechanism, fatigue life, stiffness degradation, crack width change, bending, shear fatigue properties and other aspects, this paper introduces the research progress of the fatigue properties of ordinary reinforced concrete beams.
With the refinement of research factors, load sequence, rate, factors of peak acceleration effect, size effect, the average load has also been included in the scope of the study and was introduced into the formula of crack propagation.
By using a large number of test data, the fatigue equations of different factors were obtained by linear fitting.
The main factors that affect the shear capacity of reinforced concrete beams are cross section form, concrete strength, reinforcement ratio, shear span ratio and fatigue stress level, stress ratio and so on.

In contrast to [2], [3] and [4] that investigate the influence of rolling contact loading on crack growth using stress intensity factors or J-integral measures, the current study focuses on effects of cracks on bulk material deformation.
Previous studies (a) Larger, radial thermal cracks (b) Network of thermal cracks around periodic small wheel flats Fig. 1: Examples of operational thermal and thermomechanical crackshave shown that the thermal loading induce additional thermal stresses and alter material properties of the wheel material, which will eventually promote RCF crack formation, [5].
The effect of the crack depth on the mechanical response in the bulk material in-between the surface cracks is quantified.

The growing number of earthquakes that affected the country in recent years caused a strong and growing interest in novel materials, different from traditional ones, which the composite materials, especially under form of Fiber Reinforced Polymers (FRP), belong to.
Under persistent loads, the materials that provide the best mechanical characteristics to the system in terms of long-term duration are the carbon fibers, while the matrix is ​​always of epoxy type.

They allow optimization of the product after fractionated factorial experiments in which count in addition to the desired response functions and their unwanted variability due to noise affecting the operation of the product.
Use a performance indicator compound called S / N ratio [4, 5], with which we can identify combinations of operating parameters that must be mastered and which prove the most insensitive to noise factors.
The signal/noise ratio shows additive property that the sum of the effects of factors is equal to the combined effect.
And also has the property that maximize the performance index coincides with minimizing loss of quality.
For the four factors we choose each 3 levels for each parameter.

Introduction Talc-based ceramics from the system MgO-Al2O3-SiO2, in particular cordierite ceramics, are well known for their good mechanical properties, heat resistance and especially their low thermal expansion [1], which makes them ideally suited for high-temperature applications in which high thermal shock resistance is required.
For all these the elastic constants are key properties and should be reliably known at high temperatures, because they are important indicators of high-temperature strength and affect thermal shock resistance.
However, due to the complexity of these materials their high-temperature elastic properties have not been studied in great detail so far.
Assuming a glass composition corresponding to stoichiometric cordierite, the density is approximately 2.60 g/cm3 [9] and the Young modulus of the MgO-Al2O3-SiO2 glass phase can be estimated very roughly using empirical additivity rules and factors [10], resulting in a values of approximately 90 GPa.

The sorption properties of γ-cyclodextrin polymer (γ-CDP) toward MB were investigated.
CDPs not only have the inclusion ability and the selective ability, as their parent CDs, but also have fine mechanical intensity, recyclable ability, low cost and the excellent stability.
As can be seen from Fig.2, sorption of MB on γ-CDP was not significantly affected by temperature within the studied range.
Separation factors for MB on γ-CDP Thermodynamic Parameters.
These results were consistent with the foregoing separation factor analysis.

The temperature of joint is the one of the most important factors affect the performance of joint.
As the heat transfer property of metal is excellent, when the thickness of coupon δ≤3mm (indicates Bi<<0.1), joints could be deemed as lumped heat body.
And the convective coefficients or radiation are affected by diverse factors [7].
