By studying mechanical properties of sprayed concrete mixing different proportions of iron tailings, the optimal ratio of iron tailings to replace nature sand have been gotten.
By studying mechanical properties of sprayed concrete mixing different proportions of iron tailings, we got the optimal ratio of iron tailings.
But these factors could not affect the comprehensive performance of sprayed concrete with rate of iron tailings increasing.
The strength of sprayed concrete with iron tailings proportion from 20% to 80% could meet the required mechanical properties and engineering needs.

As wail as investigating of the deformation and failure behaviour of CF/Al-MMCs, their thermo-physical properties, were determined such as the coefficient of thermal expansion.
For this reason, the technology factor αz, according to the modified ROM, gets an important role.

To achieve this goal various protocols including root surface conditioning, guided tissue regeneration, implantation of bone biomaterials and growth and differentiation factors have been proposed as stand alone therapies or in various combinations [1].
Recently, various kinds of cement have been developed, which can be used in many different ways to improve the mechanical and structural properties.
Especially, calcium aluminate cement and high alumina cement were developed in the early 19 th century and have been used widely in various architectures, due to their superior physical and chemical properties [2].
The setting time and mechanical properties were adjusted, by regulating the amount of C3A(3CaO Al2O3) and CA2(CaO 2Al2O3) [3].
In the present study, calcium aluminate bony cement incorporating LiF-maleic acid was developed, which had a fast setting time(within 60 mins), a low exothermic temperature(below 47 c) and appropriate mechanical properties for the grafting of bony defects, in order to observe, histologically, the effect of periodontal tissue regeneration in 1-wall bony defects in beagle dogs.

Analysis of Basic Properties and Comprehensive Utilization of the Hot Braised Slag Fucai Zhao, Jiantao Ju, Jielong Liao, Weiming Kong, Yaojun Dang College of Metallurgical Engineering, Xi’an University of Architecture and Technology, Xi’an 710055,Shaanxi,China zhaofucai@126.com Keywords: hot braised slag；basic properties；comprehensive utilization Abstract.
When the grinding time reaches to 15 minutes, content of slagwhich size less than 200 meshes is bigger, has reached 63.3%, the main factors influencing the stage grinding fineness is the internal structure of steel slag.
When the grinding time reaches to 30 minutes, the ratio of grinding fineness can reach to -200 of only reached 84.2%, main influencing factors of this stage is the size and content of metallic iron.
The hot brasied slag containing large metal iron particles which affect its grindability.

The main factor that affects grinding quality is the damage produced in process.
Under proper enlargement factor, surface image from workpiece placed on workbench can be obtained through the optical lens.
Enlargement factor was 500, and sampling area was selected in the center of the workpiece surface.
It could be concluded through qualitative and quantitative analysis that the number and length of cracks on ferrite workpiece surface could directly affect the surface quality, and then affect the workpiece performance.

Zhao Department of Mechanical Engineering, Henan polytechnic university, Henan Jiaozuo, 454003 Keywords: Ultrasonic vibration; Stepped horn; Node; Node position Abstract.
Zhongmao Lin [1] get the Frequency equation of stepped horn under an approximation theory, the stress concentration and transverse vibration were ignored in its theory, practically, these factors would lead to the diminution of the resonance frequency , and the node position also would be affected.
But, if take these factors in considered strictly, the analytical solution is hardly being calculated.
Choose the solid95 as the element type of stepped horn, and then set the material properties shown in Tab.1in ANSYS.
So we must reconsider the node position, or it would affect the ultrasonic system efficiency and lead to energy loss.

In order to determine the optimum joint conditions, four key process parameters affecting the joint quality of laser transmission joint of 1mm thick PET film and PC film，namely，laser power, scanning speed, clamping pressure and scanning number are optimized by response surface methodology in this paper.
Laser transmission joining for dissimilar materials with many outstanding advantages, such as high precision , biocompatibility property, low distortion to the substrate materials and minimal heat-affected zone is emerging as a major joining process, especially in present years[5,6,7,8,9].
But the most common problem is that only a few reports express the optimization of joint parameters in terms of process input factors in order to determine the optimal joint conditions.
Experimental design The experiment based on response surface methodology (RSM) with four factors at five levels each was applied to find out the optimum levels.
The following independently key process parameters affecting joint quality are identified to carry out the experiments: laser power(P), scanning speed (S), clamp pressure (F) and scanning number(N).
