Thereinto A, B, C, D represent four factors: peak current I, pulse durationTon, inter electrode gap Δ, workpiece rotation speed n.
The greater change range is, the greater effect of the factor on index is.
So we can arrange the factors(A, B, C, D) order according to the influence of these factors on roughness index from high to low: pulse duration(Ton), inter electrode gap(Δ), workpiece rotation speed n(rpm), peak current I.

Introduction Recent years, the design theory and quality control theory has made great progress in coastal moisture levee construction, but still some shortcoming, mainly reflected in the comprehensive knowledge of many quality affecting factors, quality control systems are imperfect, and so on, resulting in frequent quality accidents during the project construction especially in the coastal levee construction.
Liu Ying-xin[1] think we can do project quality comprehensive evaluation and control from the physical quality of proposed projects, quality assurance data, design quality, environmental factors and other aspects.

Analysis of the Electrical and Mechanical Properties of Cement Composite Produced with Brake Lining Waste João Batista Lamari Palma e Silva1,a*, Rosa Cristina Cecche Lintz1,b and Luísa Andréia Gachet1,c 1School of Technology, University of Campinas (UNICAMP), Limeira, SP, Brazil alamaripalma@hotmail.com, brosalint@unicamp.br, cgachet@unicamp.br Keywords: Cement mortar; brake lining waste; electrical impedance; sustainability.
Thus, there is a need to deepen studies about the electrical and mechanical properties of concrete and mortar produced with waste materials [5,6].
The physical properties of the constituent materials of the composite were determined as indicated in Table 1.
Comparison of mix proportion, electrical impedance and compressive strength In addition to the porosity, other factors may have directly influenced the results of the impedance analysis, such as the dispersion of the waste in the mixture and the contact conditions of the electrode with the mortar.
Deviations in relative electrical impedance measurements may be associated with several factors, such as the characteristics of materials and their iterations in different proportions.

The rate independent plasticity was selected on the material property defining.
Crack initiation lives are affected by local stress/strain states.

The errors are within a factor of two.
The errors are within a factor of 2.

However, the reduction of mechanical properties of laminates and the influence of composite materials under various load conditions determine battery safety, energy storage capacity and other electrical properties [8].
These factors are mainly related to the battery embedding method, composite type of and the interface bonding conditions.
Before embedding the carbon fiber laminate, ensure that the outer surface of the battery is clean, and there are no appearance defects affecting the performance and value of the cell, such as scratch, rust, stain, leakage, etc.

In this article, water morphology, thermal decomposition properties, anhydration process parameters, and water content after anhydration of sludge samples (initial solid content 20%, thermal value of dried matrix 3400 cal/g) were investigated to understand effects of water content and thermal value of sludge on its treatment by cement kiln, and effects of thermal decomposition properties of sludge on anhydration equipment and process.
Physical Properties of Sludge Chemical composition of sludge.
Fig. 1 Mineral composition of municipal sludge Thermal Decomposition Properties of Sludge The thermal decomposition properties of sludge were characterized using thermogravimetry (TG) and differential scanning calorimetry (DSC).
On the other hand, anhydrated sludge with water contents below 35% (yet above 25%) is favorable for transportation due to its favorable physical properties and no significant dust was produced.
Indeed, the difference between the designed anhydration temperature and the actual heating temperature and residence time of water are key factors for efficiency of sludge anhydration.

Research on Improving Shrinkage Performance of Cement Stabilized Gravel with Waste Rubber Particles LIU Qiyang1, a, HE Min2,b and WANG Jue3,c 1, 2Faculty of Transportation, Kunming University of Science and Technology, Kunming 650500,Yunnan Province, China 3School of Transportation, Southeast University, Nanjing 210096,China 3List all distinct addresses in the same way alliuqqiyyang@163.com, bCorresponding author: 252419553@qq.com, c1050874464@qq.com Keywords: Cement stabilized gravel; rubber particles; dry shrinkage performance Abstract: Cement stabilized gravel has good characters like high strength, good stability, anti-erosion properties and better anti-fatigue property, but it is easy to produce desiccation cracks when humidity changes (caused by evaporation), resulting in reflection crack on the bituminous pavement surface, and then influences performance and the service life of the pavement.
