Near Full Density Nano Iron-based Materials by Pulse Current Sintering Yuanyuan LIa , Yan LONGb, Xiaoqiang LIc and Tungwai Leo NGAI d Guangdong Key Laboratory for Advanced Metallic Materials Fabrication and Forming, College of Mechanical Engineering, South China University of Technology, Guangzhou, Guangdong 510640, China a mehjli@scut.edu.cn, bylong@scut.edu.cn, cxqli@scut.edu.cn, ddhni@scut.edu.cn Keywords: Nano iron-based materials; Pulse current electrical sintering; Ball milling.
Besides, the surface oxide of nanopowders retards the sintering process, and impurities are detrimental to the mechanical properties of the sintered materials.
The key to fabricate sintered nanoscale materials is to limit the coarsening of the initial nanocrystalline structure.
Therefore PECS is considered as a potential technology to manufacture bulk nanocrystalline materials with near-full density and clean grain boundaries.

As far as the establishment layout and sequence of water-saving engineering was concerned, the establishment layout of water-saving engineering was converted from first the trunk canal lining, then the branch canal, the lateral canal and the field canal lining, last field engineering to the chip layout combining with the trunk canal, the branch canal, the lateral canal, the sub lateral canal, the field canal linings and field engineering.
Key problems of Yellow River water right transfer between two cities The problem of affecting the operation of irrigation area management departments because of water fee reduction The management departments of irrigation areas shoulder the important tasks to operate and maintain the engineering and allocate and manage the irrigation water.
As far as water-saving engineering are concerned, the impermeable linings of the canals are mainly the buried and laid membrane materials lining and concrete lining.
Considering water buyers, water buyers are mainly industrial enterprises such as electric power, heavy chemical industry, coal, new materials and the renewal and innovation period of the principal parts of them is fifteen to twenty-five years.
The principal parts of one project with approval must be finished with the corresponding water-saving engineering

The Application of MASW Method on the Studying of the Vibrations in Civil Engineering Kun LUO1, a 1 East China Jiaotong University, Nanchang 330013, China aLK360111@163.com, Keywords: Surface wave; vibration; Shear wave; MASW; Inverse problems; Abstract.
Surface-wave dispersion analysis is widely used in civil engineering to infer a shear wave velocity model of the subsoil for a wide variety of applications.
While all the people enjoy the advantages of the railway, however, the buildings along the railway line will be influenced by the vibration caused by the railway, and the key point to solve the vibrations in civil engineering is to investigate the geologic parameters of the building foundation along the depth.
