Factors that affect bearing capacity of grid framework.There are several factors affect bearing capacity of grid framework in structure[4]: number of grid beams and grid columns, dimensions, amount of steel bar, concrete grade, elastic modulus of filling materials, etc.
The characteristic parameters of restoring force in the second seismic fortification line could be adjusted by altering above factors.
Altering different factors, we did the pushover analysis, set the ends of beam M3 and the ends of column PMM hinge.
By analyzing the factors that affect characteristic parameters of restoring force in the second seismic fortification line, we can figure out how the alteration of factors such as amount of steel bar in grid beam, concrete grade, sectional dimensions and the mechanic performance of filling materials affect the characteristic parameters of restoring force, the results are shown below: 1.

According to the to identify the causes of the defects, in order to find ways to solve these problems, production processes were reasonably optimized .Under the seal ring of the injection molding process, raw material preparation, injection molding and post-processing work pieces in three stages, combined with the affecting factors in producing the ring.
Table 2 Post-treatment processing conditions of the thermoplastic for the sealing ring Plastic varieties Heating temperature/˚C Holding time/h PA1010 90~100 4~10 PA6 110~130 2~8 PA66 70~80 2~4 PP 75~85 2~4 Influence factors of sealing performance Performance of injection molded parts is influenced by many factors.
The choice and control of the injection molding process technology conditions became the key factors.
It is the important factors related to the quality of parts.
Screw speed is also important parameter affecting plasticizing ability and plasticizing effect.

Polypropylene is also a semi-crystalline polymer where its properties and behaviour are affected by the thermal/mechanical properties during processing.
Introduction Polypropylene is a semi-crystalline polymer where the thermal/mechanical properties during processing play an important factor in affecting their behaviour [1].
There are many factors affecting the foaming process of polymers.
Molecular modelling technique can be used to predict the macroscopic properties as well as explaining the molecular mechanisms which will be affecting the structural/properties relationships [7].

In micromachining, the uncut chip thickness is comparable to the tool edge radius, and chip won't be generated if the uncut chip thickness is less than a critical value, besides that, the minimum uncut chip thickness affect many factors such as the cutting force, the chip's modality, the cutting surface quality, etc.
Because the minimum uncut chip thickness affects many factors such as the cutting force, the chip's modality, the cutting surface quality etc, so it's important to comprehend how to determinate it and the critical point can finally be determined.
There is evidence [4] illustrates that the coefficient of friction along the tool-chip interface is affect by three factors: ploughing, adhesion, and chip deformation.
The coefficient of adhesion on the two surfaces is determined by the properties of the two materials.

The main drawback of this material is a high level of autogenous and especially drying shrinkage, which causes a deterioration of the mechanical properties.
Introduction Alkali activated aluminosilicate materials represent an alternative to ordinary Portland-cement based materials, reduce the impact of building industry on the environment and offering new superior properties.
Type and dosage of the activator as well as the way of curing have a significant effect on the hydration course and final mechanical properties [2].
The new measurements by Impact-echo method show the possibility of using this method to assess the degree of damage incurred during hardening mortars that affects the final properties of the material [6,7] Experimental part For research purposes we produced three sets of samples.

Different from bulk, Y2O3 films involve the epitaxial relationship with substrate and the size effects in the vertical axis, which increase the difficulty in phase controlling and optimization of mechanical properties.
And Pei Lei et al. has presented a research work on Y2O3 films deposited at different target condition (metallic, transition and poisoned) controlled by different oxygen flow with their optical and mechanical properties revealed [4].
Modulus and hardness are important factors for coating application.
Also modulus and hardness could reveal intrinsic properties of material and be effected by various factors such as internal stress, phase configuration and grain size.

Composites with nano reinforcements had outclassed their counterparts in terms of the properties shown by the nano composites.
In the present work aluminium matrix has been reinforced with boron carbide and nano graphite which is added as a solid lubricant to improve tribological properties.
From this interaction plot for the overcut, there are two factors affecting the overcut, one being the voltage and other being the electrolyte concentration.
The remaining factors, current and feed rate have negligible effect on the overcut.

Mechanical Properties.
The mechanical properties at different SEED process conditions were demonstrated for the T5-temper condition.
The mechanical properties and particularly the ductility were significantly affected by the change in the SEED process parameters.
The latter are among other possible factors that could have introduced some variations and influenced the overall response of the material.

Then transformation temperature, the shape of cell area, and mechanical properties were evaluated.
This research aims to design the Peripheral stent for treatment of stenosis in tortuous vascular and investigate the effect of braiding conditions and heat-treatment temperatures on mechanical properties.
But the superelasticity properties cannot be confirmed in specimens heat-treated at 450°C and 500°C because the RAf is higher than 37°C which was the testing temperature.
When considering these factors which are braiding pattern and structure under kinking.
