And much affected the mechanical strength.
Microwave heating may be caused the degradation of KGM, And KGM thus affecting the water absorption, thereby affecting the films body volume expansion.
Thus becoming the process of films degradation directly affects the integrity of the films body factors.
KGM greater impact the mechanical properties of KGM/starch composite films, it should not be mixed with too much Starch.

Furthermore, it should also have good moisture resistance, mechanical strength, flame retardant, proof tracking and easy to process and other properties.
Electrical properties, thermal properties, mechanical properties, corrosion resistance and other properties of insulation material are closely related with its composition and structure, and is affected by temperature, humidity, mechanical vibration, pollution and many other factors.
Safety requirements and testing of insulating material parts There are many factors that affect the safety of the use of electrical accessories, the properties of the insulating material is the most critical component, therefore, the safety testing of the detection member of insulating material is very important.
Insulating material parts are also affected by temperature, humidity, and so on, causing aging, resulting in lower mechanical properties.
The following table gave IEC60884 standard as an example to illustrates the mechanical properties of electrical accessories products’ main test items.

Experimental Research on Tensile-shear Behavior of Spot-welded Lap Joints of Ultra-high Strength Steel Yuehua Liu1,a, Huiping Yu2,b, Weiwei Wang3,c, Xiaoyang Li4,d, Shujun Chen5,e 1, 2, 3, 4, 5 College of Mechanical Engineering and Applied Electronics Technology, Beijing University of Technology, Beijing 100124, China aliuyuehua@emails.bjut.edu.cn, byuhuiping@bjut.edu.cn, cwwwaptx@emails.bjut.edu.cn dlixy@bjut.edu.cn, esjchen@bjut.edu.cn Keywords: Ultra-high strength steel (UHSS), Spot-welded, Mechanical properties Abstract.
Numerical simulation based on some assumptions is the common method to research mechanical properties of spot welding joints under tensile-shear load, Baohua Chang [3] has established a computational model that consists of nugget, HAZ and base metal for the single point spot welded lap joints, and the whole stress distribution in the joints is obtained, the results show that high stress concentration around the spot weld edge may be the determinable factor for initializing and propagating of the high cycle fatigue crack.
Xingxing Xie [4, 5] adopts the local stress analysis method to study the nonlinear mechanical properties of the welded spots in a tensile-shear spot-welding lap structure, the nonlinear finite element model is established under the condition of elastic-plasticity, to analyze the strain-stress distribution rules under various loads, the conclusion indicates that the shear stresses should be the main criterion for the safety evaluation on the spot-welded structures.
Conclusions By means of experiment, including tensile-shear testing, hardness testing and morphology observation, this paper makes a research on the mechanical properties of spot welding structure of ultra-strength steel, conclusions are drawn as follows: (1) The results of Vickers hardness testing indicate that the maximum hardness of the structure is located at weld nugget, and the minimum hardness appears in heat affected zone.

The model indicates that the main factors of crystal detachment are vibration frequency and amplitude as well as cooling temperature of the chilling solid surface.
The effects of the above three factors on the actual crystal detachment behaviors were studied experimentally by using a transparent NH4Cl-70%wtH2O alloy.
Introduction Crystal structure in castings is of vital importance for its processing and application properties.
The main factors determining crystal detachment were also discussed.
Conclusion Through the primary phase on the grain stress analysis , A solid surface crystal chill free mechanical model in the vibration conditions was established, it is found that the main factors affecting the free crystal include vibration frequency , amplitude, chilling temperatures and surface state, in which the vibration frequency of the maximum amplitude of Secondly, chilling temperatures and relatively small surface state .Experiment investigated crystal chill free behavior of NH4Cl-70wt% H2O solution on the surface of LY12 aluminum alloy, the experimental results with theoretical models get a better fit .

The addition of OA into NR/BC affect vulcanization properties of NR/BC masterbatch that retard the cure time of their compound.
Their cure and mechanical properties were characterized by Oscillating Disk Rheometer (ODR) and mechanical tests.
The effect of BC and OA loading on mechanical properties of vulcanizates.
This could be similarly explaining the result of the tensile properties of the vulcanized NR presence OA, the increasing of polymer chain flexibility due to added plasticizer, which affected to decrease the mechanical properties of the vulcanizates [6].

Cold cut method was applied to remove heat affected zone on the coupon which might cause changes in properties of the material.
Hence, there are other principal factors that dominate the corrosion process at all sites.
The measured metal loss of the coupon which buried underground is mathematically caused by so many factors including soil chemical contents and other third party factors such as pollution.
This is in line with the previous statement where soil engineering properties may pose minor influence on corrosion rate, hence not the most influential factors.
Other factors (such as chemical content, pH) may contribute more in this case.

CFST Arch Bridge under pressure mainly stability is one of the key factors restricting its development.
Most of the arch of instability belongs to the second type of instability, and that the non-linear deformation of the structure is nonlinear state, the mechanical properties of the structure also change from elastic state into nonlinear state.
In this paper, based on nonlinear and stability theory and using the finite element software ANSYS, parameters of affecting the main arch stability were studied.
As a predominantly compressive structure, the stability of CFST Arch Bridge becomes one of the key factors restricting its development.
Influencing Factors The influence of width-span ratio.
