Stone has reported that the formation of internal defect is the main factor of the impact load to the wheel not the roundness.
Mechanical Characteristics of Wheel Tread If the hardness is known, other physical features of the material can be known.
In addition, hardness needs to be measured to property where is severely exposed to heat or which materials are improperly used because it is related with properties of the material.
Conclusions The various factors to the damage to the HST power car wheel by metallurgical analysis, mechanical analysis and field test is investigated.
The main factors to the damage to wheel tread for HST power car are; 1) The fine cracks occurred by the plastic deformation, which is thought to affect the traction force. 2) The hot spot occurred by the brake block, which cause the frequent flat of the wheel tread. 3) The early reprofiling raised by the tread damage of the HST power car wheel is more affected by the flat resulted by the hot spot of the brake block than the fine crack initiation resulted from the plastic deformation.

It has been reported that by improving surface properties of coating layer the fixation of the bone to the implants can be enhanced [9].
Therefore, coating of stainless steel with biocompatible materials such as hydroxyapatite (HA, Ca10(PO4)6(OH)2) is an easy way to prevent corrosion of implants as well as improving the osseointegration properties.
Surface morphology of implant material is an important parameter which strongly affects cell attachment and protein adsorption [10].
Therefore size and volume fraction of the porosities are two important factors for osseointegration properties of implant materials Table 2 Data calculated by Image analysis software Sintering temperature ( °C) 600 700 800 Porosity volume fraction (%) 18.259 5.056 0.883 Porosity mean size (µm) 15 6 < 1 Therefore it can be concluded that HA coating sintered at 600 ºC shows best result for circulation of the body fluid although porous structure may result in lowering the mechanical properties of the coating.

By setting up the model of tree, mine safety management researching analyses various elements about relationship and effect under affecting each other.
With the sustained development of China's mining industry, production safety accidents have occurred and it poses a serious loss of life and property and national economic. [1] The direct cause of mine disasters are insecurity of human behaviors and insecure mining operating environment.
Clearly, on-the-job injuries due to unsafe work behaviors remain a significant problem nationwide [3] The Necessity of Building Systematic Safety Management System In the mining industry alone,1,430 workers were killed in both metal/nonmetal and surface/ underground coal mines from 1992 to 2000 [4]Due to the mining industry belonging to a high-risk industries, many instable factors, such as the uneven quality of personnel, various production processes, complicate operating conditions, aging equipment failure and so on, which affect the safe production of mines to a varying degree and produce tremendous threat of personal safety, therefore, the construction of the safety management system is particularly important.
Mine safety management regard safety management as a system, through the optimization of various factors together, the mining safety management also optimized.
The Design of “Tree” Type System of Safety Management System Mine safety management regard safety management as a system, through the optimization of various factors together, the mining safety management also optimized.

Compared with the casting, the forging rack can greatly improve the mechanical properties and the service life.
The reliability of its operation directly affects the performance level of whole machine system.
Compared with casting forming, the forging can eliminate the defects of the casting state caused by the metal in smelting process, and optimize the microstructure of the metal, and also can improve the mechanical properties of the parts by keeping the integrity of the metal flow line [7-11].
When calculating the size of blanking of the heavy rack for ship lift, some factors should be conceded: 1) In the process of free forging, the metal will flow along the axis of the forging, which will reduce the section metal and increase the forging length.
