The mechanical properties of the films were measured on a universal testing machine, and the dissolution rate of SF was examined by ultraviolet spectroscopy.
Nevertheless, the addition of glycerol has a direct influence on mechanical properties and water solubility of the films.
In order to obtain the best addition amount of glycerol to prepare SF/ PP blend films with ideal mechanical properties and water insolubility, the effects of addition amount of glycerol on the properties of the blend films were investigated as a reference for further research on this blend film.

The impact of this effect on mechanical properties is briefly considered.
This may influence mechanical properties of the weldments and this effect should be quite pronounced in magnesium alloys.
The direct correlation between the texture and mechanical properties of magnesium friction-stir welds has been shown in AZ61 magnesium alloy in 2003 [4].
Therefore, the specific textural heterogeneity inherent to the FSW process should also be taken into account during evaluation of mechanical properties of the FSWed material.
The inhomogeneous texture distribution may significantly affect mechanical properties of the friction-stir weldments.

The relationship between these factors can be complex and is determined by many factors, including the materials of the surfaces in contact, the loads applied, and the operating conditions. [22,24].
Factors such as friction, wear, noise, lubrication, and rough surfaces have implications for motion systems [26,27].
The association between these factors is complex and determined by different circumstances.
Notably, only two current models address these factors, and they primarily focus on scenarios without lubrication.
The materials were tested under diverse load circumstances and wear routes to completely evaluate their performance properties. 2.

There are many factors affecting the quality, precision, microstructure and performance of LMDS-deposited parts.
Accordingly, the dilution ratio is not only an important index to judge the laser cladding quality, but directly affects the interlayer bonding strength and performance quality of as-formed metal parts.

Pointing at the deformation characteristic of continuous wall, the factors which influent the deformation of continuous including the intrinsic mechanical characteristic and time effect in the construction area.
Deformation factors There are two main aspects that influence the deformation of underground continuous wall,one is a series of internal factors like the depth ratio and reinforcement ratio of the underground continuous wall, the other is the construction conditions and time effect.
In this research, Hu Feng collects 58 monitoring data in Shanghai arear and apply the statistical theory to analyze the relationship among the displacement of maintenance system, soil properties and the system stiffness.
The purpose of this research is to explore how the model parameters affect the sensitivity and safety factor of cell wall stability.
In the deformation prediction progress, more factors should be taken into consideration to make it more comprehensive and reasonable.

Factors Influencing the Precision of Forming Workpiece
In order to meet the precision requirements of the workpiece, it is crucial to understand the factors affecting the forming precision and find the improvement strategies.
The important factors include the manufacturing and assembly accuracy, elastic deformation of press frame, slider clearance, and forging process, etc.
Considering that the shift can be eliminated by a reasonable balance device, the direct factor affecting the forming error only includes elastic deformation of die and lower beam.
Therefore it is naturally concluded that hypothesis that lower die has property of near pure flexible is sound.

Firstly, according to large number of examples of instability disaster in mines at home and abroad, influence factors of goaf stability was analyzed, including characteristics of surrounding rock, conditions of engineering geology, engineering properties, structure parameters of goaf and other artificial mining and time etc.
Introduction Influence factors of surrounding rock stability on underground goaf are numerous, including joint properties of rock mass, groundwater, gas, size of goaf, time, buried depth, supporting conditions, as well as high temperature, high pressure in deep mining, etc.
And moreover, it suffered from coupling effect of multi-factor and multi-field, making the underground goaf show high uncertainty of mechanical deformation properties, nonlinearity of constitutive relationship and mutation of failure process.
These factors are variable, with spatial effect.

Introduction
As one-dimensional functional materials, whiskers have attracted great attention because they exhibit unique structure and various excellent physical, chemical, and mechanical properties [1], it showed excellent prospects for application materials in reinforcing and toughening.
As a new material, magnesium carbonate whisker has a incomparable properties compared with conventional whisker.
Influencing factors of preparation process.
Stirring rate is one of the important factors which affecting the particle size and the particle size distribution, magnesium carbonate whisker aspect ratio first increases and then decreases with the increase of the stirring rate.
Other factors also affect the formation of magnesium carbonate whisker, such as: the pH of the reaction solution, the reaction time, the added amount of surface active agent.
