Referring to the effects on properties of corn starch films, the most important factor was the glycerol concentration, the following factors were the pH value of the coating liquid, the CMC-Na concentration and the corn starch concentration.
During the last few years, biodegradable polymers with suitable mechanical and physical properties have received particular attention to replace petroleum-based plastics [6,7].
Testing corn starch film properties.
Comprehensive properties of the film were estimated.
In the best condition A1B1C2D3, the most important factor which affected the properties of the film was the glycerol concentration, the following factors were the pH value of the coating liquid, the CMC-Na concentration and the corn starch concentration.

A new measurement apparatus was developed to characterize the dynamic liquid moisture transfer properties of textile materials such as textile fabrics, based on the mechanical equipment, microelectronics, sensors and control system.
The dynamic moisture transfer properties is related to the thermal-wet comfort sensations of clothing, which together with tactile comfort and pressure comfort are identified as the three major sensory factors of clothing comfort [2].
The mean values of the liquid moisture transfer properties measurements are summarized in Table 2.
Therefore, the fabrics’ behaviors significantly affect the liquid moisture ransfer properties of all indices, and the measurement method and the indices defined are effective for characterizing the liquid moisture transfer difference between two surfaces of textile materials.

The main factors affecting the movement and deformation of the surface (1)Ratio of mining depth and mining thickness Different mining seam thickness, resulting in subsidence gob collapse of overlying strata with different crack height, with a high degree of surface collapse crack forms and degrees of movement and deformation damage plays a decisive role
(2)Mining methods and roof management methods Mined subsidence processing methods are mainly based on the top floor and the mechanical properties of rock layers composition, thickness coal seam, the special requirements of the ground (rivers, railways, buildings under mining) and other factors to select [2]
Depending on the different risk factors that impact on the natural gas pipeline, and now scores of the factors given in Table 1-2 were mining methods, ratio of mining depth and thickness, overlying lithology, subsidence gob formation time, the level of distortion , tilt effect radius, and the sinking value of the mined subsidence type score.
Inflection point offset d = 0.05H, subsidence coefficient =0.8, mainly affecting the tangent tgβ = 2.0, horizontal movement coefficient b = 0.25[7].

Introduction One of the major world tendencies in the development of engineering industry is technological development and creation of high-tech materials that able to have the necessary physical, mechanical and chemical properties and, as a rule, having a certain structure.
The basic properties of the sintered porous slide bearings [2], are determined by their functional qualities: self-lubricity, good running-in ability, wear resistance and strength.
The combined method of the process has the wide range of controllable factors, affecting on the quality level of the formed surface, and therefore, it is convenient and effective to use in the forming process of the hard-to-punch and the heterogeneous materials.

To understand the behavior of the adhesive material, mechanical characterization is done on bulk adhesive specimen.
Another advantage of the foil gauge over the wire gauge is that it has greater heat-dissipation properties [1].
The influence of the properties of the underlying material, and of adhesive properties for strain-gauge design was demonstrated by numerical examples.
The results show that the gauge factor depends on the geometrical and elastic properties of both the strain gauge and the structure under investigation.
Furthermore, it was concluded that the thickness and stiffness of the adhesive layer can markedly affect the gauge factor.

The resulting model allows us to quantify the influence of rheological factors on the completeness of the water-oil displacement and to calculate the performance, taking into account the component composition of the hydrocarbon phases.
Taking the Samara Region oil fields as an example, the article shows that the quality of design is unsatisfactory when the bundled software being used does not take into account specific non-Newtonian properties of the high-viscosity oil.
Any high-viscosity oil has structural and mechanical properties and behaves as a non-Newtonian fluid, depending on the concentration of high molecular substances, the component analysis of casing head gas, permeability and temperature.
An unfavourable combination of these factors leads to an increase in viscosity, deceleration of the oil filtration rate, and the progressive bed water influx.
This means that in a certain range of pressure gradients, the rates of water influx will be actively influenced by the viscoplastic properties of the oil along with the rock filtration properties.
