The Identification Analysis for Macro Distributions Curves of Functionally Graded Materials Properties Based on Materials Components ChaoFeng Ge1, a 1State Key Laboratory for GeoMechanics and Deep Underground Engineering, School of Mechaics, Architecture and Civil Engineering, China University of Mining and Technology, Xuzhou 221008, China agechaof@163.com Keywords: Functionally graded materials; Microelememt method; material components Abstract.
Though the original research of FGM was begun on releasing thermal stresses, the idea was gradually applied to the research and conception of other functional materials which are widely used and developed in some other important regions such as aerospace, energy sources, electron, chemical engineering, optical materials, biological engineering, etc.
The research work on FGM was started as a specific functional material of aerospace engineering.
After one positive and one inverse analyses, the macro gradient distributions functions of functionally graded materials properties parameters needed in engineering calculations can be inversed and identified by the known material components given in the production process.
Conclusions From the above calculations analyses, we can know that there are many advantages. through one positive and one inverse analysis, the macro gradient distributions functions of functionally graded materials properties parameters needed in engineering calculations can be inversed and identified by the known material components given in the production process.

In order to solve technological key problem of metallic rubber in the respect of engineering application, based on porous materials theory, this paper explored the method of nonlinear constitutive relationship constructed, thus in view of the effect of heat treatment technology on nonlinear constitutive relationship of metallic rubber, static experiments are made for seven kinds of tempered metallic rubber and seven kinds of untempered metallic rubber, it was found that each coefficient of nonlinear constitutive relationship of tempered metallic rubber was bigger than that of untempered metallic rubber, and the deformation of tempered metallic rubber was smaller than that of untempered metallic rubber.
Such a material combines the rubber-like elasticity with porosity, and, in this regard, it differs from all other materials.
In the field of engineering, we wish to achieve appropriate metallic rubber structure effectively and quickly, but there is great distance between theoretical description and practical engineering, and the distance is a key technique problem affecting metallic rubber structure used widely.
In order to solve the problem, based on porous materials theory, the method constructing constitutive relationship of metallic rubber is studied.
The research fruit has an important significance for engineering application of metallic rubber and manufacturing quickly isolator made of the material.

Some key problems of development in FCEV DC/DC converter are particularly analyzed, including of reliability, efficiency, static and dynamic characteristic, etc.
High Power DC/DC converter is one of the essential key devices in most developing FECV at present, due to the soft electrical output characteristics and the consideration of control system of the vehicles.
The characteristics, such as high power (from dozens kW to hundreds kW), high efficiency (more than 96%), security and reliable and small in size, are required by the DC/DC converter in fuel cell electrical bus, therefore, the study of high power and high efficient is of important theoretical significance and engineering application value to the development of FCEV[1].
FCEV is one of the main directions of future advanced vehicle, and the breakthrough of key technology used by DC/DC converter in FCEV will boost the research and development of FCEV.

It is shown from the practice that the laser remelting compound technology followed boronizing shall be widely used in surface hardening of petrochemical key parts.
Table 1 The results of abrasive particle wear test Material NO.
When two kinds of cracks encounter or enlarge to the surface, the sample materials shed off in the micro- particle and form the fatigue wear and micro-fracture wear.
It is shown from the production that not only the materials with high hardness but low fracture toughness is not in good anti-wear performance but also the ones with high fracture toughness but low hardness is not in good anti-wear performance, only the fracture toughness and hardness fit together effectively, the material can be in good anti-wear performance.
