The isotropic linear elastic material [3] (45 steel) is used in the carriage, and the material parameters of the isotropic linear elastic material (45 steel) are: E = 2.1×1011 N/m2, μ = 0.3, ρ = 7800 kg/m3.
(4) As the material of the carriage is 45 steel, the material’s damping ratio (0.125) is taken into the formula (4), and the module of the frequency response function is got while resonance.

Treatment of compacted filling foundation According to the style of filling material, various methods of treatment of compacted filling foundation can be used.
The filling material has high hardness, stable performance and erosion-resisting characteristic [6].
Based on figure of building, characteristic of structure, geologic characteristic, construction condition, construction equipment and material, general analysis and scientific design is put forwaed to make sure that the building is steady and safe.

In another way, it is very hard to form hydraulic membrane in coupling friction pair because of poor lubrication of pure water, and it is really necessary to use some special materials, structures and techniques of high machining precision to solve the problems of dry friction and clogging [2].
However, because of unbalanced radial force resulted from large pressure of outlet and small pressure of inlet when high-pressure gear pump treated, serious wearing between axle journal of drive shaft and bearing hole exits and causes not ideal dynamic characteristics of pump, with reduction of volumetric efficiency and bad control of leakage after long run. 2.New structure design and experimental research In this design, a rectangular groove iss set between the inner-hole of front and back plates towards the inlet side of high-pressure gear pump (as Fig.1 and Fig.2) to make a connection for the high-pressure liquid at the inlet of high-pressure gear pump.
The material of floating plate was ADC12, with its elements: Si=(9.6～12)%, Cu=(1.5～3.5)%, Mg=0.3%, Mn=0.5%, Ni=0.5%, Fe=1.3%, Zn=1%, allowance of Al=(79～85.3)%.
The material of gear and shaft was 20CrMnTi.

The products of akund fibers have good wearing characteristics, for example, good hydraulic conductivity which can make the body excretion of sweat through the fabric easily, so the discomfort will be reduced and big holes inside of the fibers make them a warm material [1~3].
Fig .2 The surface of akund fibers Material and Method.
Mixed fibers of akund and cotton fibers are used as materials.
Carding processing length (see Fig. 3) is an important parameter if we want to transform the raw material into a smooth coherent web by disentangling and ordering the fibers and eliminating the unwanted impurities, and it is suggested that carding processing length is longer than the main length of fiber.

The Effect of Carbon Content in Filling Alloys on η Phase Formation in the Interface Zone of YG30 and Weld Bead Xiujuan Zhao 1, a, Chunhuan Chen 1, b, Yuan Sun 1,c, Dexin Yang 1, d, Kohsuke Tagashira 2, e 1Shool of Materials Science and Engineering, Dalian Jiaotong University, Dalian, 116028, P.
Experimental Cemented carbide YG30 (70%WC + 30%Co in weight percent) and steel 1045 (ASTM) were selected as base materials in this work.
It can be seen that when the filling material is carbon free, the thickest η phase zone up to 120 µm is gotten.

Introduction Development of modern technologies requires new materials that exhibit extremely hard magnetic properties.
The low intensity of remanence relaxation (H=0 T) for x = 0.08 can be explained taking into account that this material is magnetically hard.
The obtained results from generated as well as empirical curves indicate that the proposed approach leads to physically reasonable conclusions and can be used in the field of magnetic characterization of hard magnetic materials.
