In order to overcome these problems, we design piezoelectric transducers as a sandwich lamination and we adopt smaller expansion coefficient, high Q value of the piezoelectric material to make transducer ends, and then connect it by nut.

Fig.6 Curve of seismic influence coefficient α Response Spectrum Analysis.In ANSYS program response spectrum analysis are carried out based on simulation model and seismic parameters above.Single-point response spectrums of 7-degree intensity of seldomly occurred earthquakes in x and y directions are applied to the structure.By SRSS(single-point response spectrum) method modal results are combined and responses of displacement as well as inner forces of the structure are obtained,as shown in Fig.7-9.Permissible parameter values for the timber material are [6,7]: Displacement:0.035m; Tensile stress:8.5MPa;Compression stress: 12MPa.

Analysis of Basic Oxygen Furnace’s Temperature by the Flame’s Emission Spectrum Lingfei Xu1,a, Wusen Li1,b, Shixue, Xu1,c, Jia Li1,d, Yongqing Wang1,e 1Group 432 Department of Optical Engineering Nanjing University of Science and Technology, Nanjing, Xiao Ling Wei 200 China ajsj900@hotmail.com，bliwusen@mail.njust.edu.cn, cete_corner@yahoo.com.cn, dlijiafeifei@sina.com , esyusqing@163.com Keywords: emission spectrum, FES, spectrometer, BOF Abstract: The flame of basic oxygen furnace is the most important evident in the steel making process.
In the combustion of material with high concentration of carbon, there exists the emission peak in its flame spectrum at 527nm to 616nm which is the Na.The emission line could be treated as the atomic transition between two energy levels.

Solar power generation 1.1 The principle of solar power generation Solar thermal technology means absorbing solar radiation heat energy to produce electrical energy power; it is an important way in solar energy use, including two types: one is to use solar thermal for power generation directly, such as semiconductor or metal material temperature difference power generation, hot electron and thermionic generator of vacuum device and alkali metal thermoelectric conversion and MHD power generation, etc.; the other kind is to gather solar energy heating to produce superheated steam to drive thermodynamic device to drive the generator power generation, which convert solar energy to electricity.
