The main functions of this system are that the user puts forward his request for information service to the digital library according to his own research field and need for information, that the specialist service module solves the request by intelligent retrieval and screening and organizes the digital resources and other contents, and that the personalized page is tendentiously customization at last and the content is shown Along with the development of digital libraries, digital resources are increasing daily, but as a lot of users are not familiar with the searching methods or technology of different database resources, it is a more difficult process for users to find their necessary materials from the database of the libraries.

To solve these problems, material hybrid structure utilizing aluminum alloy and steel is recently being studied [1~2].
As shown in Fig.6, at the aluminum alloy side, there are three zones of hardness variability, which are Al base material, Al heat affected coarse grain zone and fine grain zone, whose average hardness are 1.17, 1.25 and 1.30GPa respectively.
At the SPCC side, the center of plate, the maximum hardness obtained is 3.74GPa, and that is 1.7 times as high as that of SPCC base material.
Fig.6 Distributions of hardness across the interface Fig.7 Hardness of Fe2Al5 layer · Al base material, coarse grain zone, 　　　　　　 (10.5kA×0.4s) 　　 fine grain zone(10.5kA×0.4s) 3.2.2 Tensile shear strength The relationship of welding time and tensile shear strength was introduced in this section.

In the Criteria of evaluating green architecture (GB/T50378一2006) published on June 1st in 2006, green architecture is defined that it is a kind of architecture to save energies (save energy, field, water, and material) to its maximum extent during its life cycle.
There are more than 100 items, including the indoor and the outdoor environment, energy saving and utilization, water saving and water resources utilization, material resource use, indoor environmental quality, building electrical, operation management, for the total of seven kinds of technical indicators.
And it can make a comprehensive assessment of the whole process, including implementing the design program, the building materials and construction equipment for building.The third party evaluation combined the external evaluation with the internal expert appraisal.

The kinetic energy of the high velocity electrons is converted in to thermal energy that melts and vaporizes the material.
When these electrons impinge on a material, they are stopped and, in the process, give up their kinetic energy.
This increases the amplitude of lattice vibration of electrons, which in turn raises the temperature of the material that is sufficient to melt and evaporate.
If we ignore the extreme values, it can be inferred that the If weld is less by 20mA from If sharp for a good weld formation in keyhole welding, irrespective of the work distance or material thickness.

The bridge using the new type solid round rigid suspender which diameter is 120mm and the material is 35CrMo.
The internal is the steel material properties and stress concentration, and the latter mainly depends on the bar joint form, connecting method, cross-sectional shape, etc.
According to the operating requirement of suspender and material properties of 35CrMo, the static failure load of suspender should be no less than 4722 kN.
It can be found from the figure there is a linear relation between the measured strains and the applied loads of the short and the long suspender models till the test load(4722kN), indicating that the material remains in a linear elastic state.

Introduction Copper is raw material of great strategic significance in the national economic development and security [1,2].
The regeneration of copper is better than other metals, with the enlargement between the demand of copper material and mine copper production, the scrap copper has also become an important source of raw materials in copper production, and the research of scrap copper smelting has been paid more and more attention.
