Effects of Ozone Treatment on Wool Morphology and Mechanical Properties Jun Wang a, Fanggang Ningb, Weidong Yuc Textile colleague, Donghua University, Shanghai 201620, P.
The aim of this study was to investigate the ozone treating effects on wool scales and wool mechanical property through experiments and observation.
For this purpose, a detailed investigation on the role of mechanical properties surfacing topography, changes in component and membrane structure were investigated.
For the scales is the element factor for shrinking, so this study is of great significance to the work of shrinkproofing.
Results and discussion Effects on wool fabric mechanical property.

The surface micro-temperature of sliding, rough bodies is an important factor affecting contact properties, such as chemical reactions of automatic injectors for medicine and chemical processes and surface failure of micro- and macro-devices.
The affecting parameters include pressure, roughness, sliding speed, Peclet number, and thermal conductivity of rough surfaces.
Sliding speed and thermal conductivity played the most important roles in affecting the maximum micro-temperature rise.
During the high speed transient process, the micro-temperature of peak contact spots has a different distribution, and affects the adhesion and tribology properties of materials under different operating parameters.
The mechanical properties of the upper and lower blocks, including elastic modules of 7 × 104 N/mm2, Poisson’s ratio of 0.3, and hardness of 0.6 Gpa, were used in this work A sinusoidal wave was used to simulate the asperity surface.

However, the presence of lead in the composition of such bronzes significantly decreases their mechanical properties.
In lead tin bronzes there is an addition of one more component – tin, which significantly contributes to the formation of mechanical properties.
The presented changes in the structure of the casts are bound to affect their mechanical properties.
But the crucial factor determining cast properties is likely to be the presence of a supersaturated solid solution of tin in copper with high hardness.
It seems possible that the tribotechnical properties are critically affected rather by the hardness of copper matrix than the amount of the electron compound or lead inclusion shape.

Factors affecting the weld quality 2.1.
Rotational speed Rotating speed is one of the main factors affecting the frictional heat.
So more factors can be used by less runs.
Breakdowns caused by random factors, 2.
Underwater friction stir welding (UFSW) is a modern underwater welding technique which consumes less energy and gives improved mechanical properties.

To improve electrical automation control equipment’s reliability, the job should be promoted to a strategic height so as to assume and effectively control the factors affecting the reliability of the equipment, thus ensure the accuracy of reliability test.
Analysis of Factors Affecting the Reliability of Electrical Automation Control Equipment From the reality, the current electrical automation control equipment in our country has low reliability, which causes great obstacle for China's economic construction.
And summarize these factors.
Certain environmental factors such as electromagnetic waves, mechanical conditions and the climate cause a certain degree of influence on the reliability of electrical automation control equipment test.
In addition, in the using process of machinery, due to mechanical factors of the process, mechanical condition may have electrical parameters which can change electrical automation control equipment’s, and even cannot run the normal operation of electrical automation control equipment.

., Ltd Shaoxing, Zhejiang, 312000, China astructxing@163.com, bdlh@zcg.cn Keywords: PFST; mechanical properties; hoop coefficient; slenderness ratio; experimental studies Abstract: The main purpose of this paper is to research the mechanical properties of polyurethane filled steel tube PFST members with different hoop coefficients and slenderness ratios under axial compression by experimental studies.
Introduction With the development of materials, polyurethane as a new kind of high-performance material with its superior mechanical properties is widely used in marine engineering and civil engineering.
Influences of hoop coefficient and slenderness ratio on mechanical properties of members and the present conditions have been considered, all physical parameters of specimens are shown in Table 1.
Influence factors 4.3.1.
Slenderness ratio’s influence on properties of members.

Besides, stirring conditions, forming and curing conditions together with the influence of curing conditions on autoclaved sludge bricks’ mechanical properties are discussed.
The brick’s mechanical properties, including compressive strength and flexural strength, are tested in light of the National Standard “Fly Ash Brick” (JC239-2001).
In light of the existing researches on autoclaved sludge brick, the factors affecting the properties of autoclaved sludge brick include the ratio of raw materials, stirring intensity, forming and curing condition and autoclave curing condition.
The choice of factors and levels is listed in Table 2.
The reasons are as follows: during the process of autoclave curing, the hydration reaction occurs fully between lime and fly ash, generating a lot of hydrated calcium silicate minerals, including C2SH (A), CSH (B) and tobermorite, and CSH (B) and tobermorite are very important factors to the physical and mechanical properties of bricks.

This study observed that mechanical properties of join.
It depends on material at retreated side cause into the mechanical properties of join consist of material over retreated side.
The aim of this study is finding the suitable with micro and macro structure and mechanical properties.
This work studied in various conditions with influence with mechanical properties of join.
The rotation speed and welding speed of joint are a significant factors.

So the physical and mechanical properties and the composition of rock strata, the conditions of aquifers, and the locations of aquifers all affect on the stability of roadway.
In turn, pore pressure changes cause mechanical deformations to occur.
Making solid-fluid coupling analysis in FLAC3D, the result of seepage calculation depends on the basic model of simplification and modeling, at same time, the characteristics time and boundary conditions must be also considered, the two factors will affect the calculation results of the credible degree [5].
According to different rock properties, two models are established, model Ⅰ: impermeable model; Model Ⅱ: seepage from roof.
Water is one of the key factors to influence the stability of roadway, seepage makes the strength of surrounding rock sharply reduce, and the roof, two sides and floor appear serious deformation.
