Foreword With the development of modern science and technology, the problem of the materials’ friction, wear and lubrication under different conditions has been paid more and more attentions, the research of tribology in special service condition has became an important research hotspot[1-3].
Compared with a figure 4(a), some solid lubricating film surfaces are rough, softening of material is obvious, the wear surface is full of deep traces of the furrows, the surface is covered with softened molten material, adhesion spalling pits also appear on localized surface, but it can still play the role of self-lubricating materials, and compared with the experimental temperature of coating is 300°C, it has less effective friction, but still has high strength, the deformation of the substrate under surface of grinding crack is ​​slight, WS2 still maintains the original shape, indicating that the high temperature tribological property of composite coating is better.

Sound Radiation Analysis of Thin Plate Using FEM and BEM Method Shanbao Pei1,2,a, Rongzhong Liu 1,b 1School of Mechanical Engineering, Nanjing University of science and Technology, Nanjing, Jiangsu, 210094, China 2School of Mechanical Engineering, Anhui University of Technology, Ma’anshan, 243002, China ashanbaopei@163.com, bliurongz@mail.njust.edu.cn Keywords: Sound radiation; Thin plate; Sound Power Abstract: The relationship between the sound power and the stimulated frequency of thin plate is analyzed, and the influence from frequency is also introduced.
In the process of solving, the solution of all matrix is only related with the geometric shape and stimulated frequency of structure, therefore impedance matrix is related to the geometric shape and stimulated frequency of structure, is unrelated with the material properties, boundary conditions and stimulated source position.
The sensitivity of the impedance matrix is zero when the sensitivity of structure material characteristic and the sensitivity of structure boundary condition are analyzed.

As a result, not only is the original material space preserved, but the fundamental essence contained in the space is also continued.
Analysis of Regenerative Protection Methods for Urban Historic Areas The regenerative protection is to superpose the point features and spatial elements of history and culture with the functions of commercial activities to form not only material carriers like architecture and featured landscape, but also spaces with cultural and historical implications as well as functional conveniences.
