Eissa Physics Department, Faculty of Science, Beni-suef University, Egypt mostafa.eisa@science.bsu.edu.eg Keywords: Alpha Particles, CR-39 Polymer, Optical Band Gap Energy, Track Etch, Urbach Energy Abstract The track etch detector, CR-39, in common use is the most sensitive to recording charged particles.
Thus, the present work was verified by the UV-vis spectra of CR-39 polymer materials which irradiated with different alpha particle energies (2.17-3.95 MeV) at a constant fluence and different etching times (1.500, 3.00 and 6.00 hrs).
The optical absorption method used for the investigation of the optically induced transitions which can provide information about the band structure and energy gap in crystalline and non-crystalline materials.

Research on Seismic Performance of the Steel-Braced Frame Changjiao Hu 1,a, Xinwu Wang 2,b 1School of Civil Engineering,Henan University of Science and Technology,471023, China 2Department of Civil Engineering, Luoyang Institute of Science and Technology, 471023, China a email: 1246686577@qq.com , b email: wxw197100@sina.com Key words:Steel-braced frame,Seismic performance,supporting forms Abstract:With the purpose of comprehending the seismic performance of steel-braced frame system better and more comprehensivly, the paper overviewed and summarized the hysteretic performance,ductility and energy dissipation performance of the steel-braced frame based on a large number of abroad documents.The force was on the seismic performance of steel-braced frame in different supporting forms and the insufficiency in the research.
Pseudo dynamic test.Pseudo dynamic test was an online test that combined the loading system with the computer .By pseudo dynamic test,we could analyzed the load feedback, acceleration and displacement reaction, the changing process of strain of the steel frame.It was beneficial to analyze the elastic-plastic stage performance,observe the change of structural performance and could carry out the seismic test for large size specimen .However it couldn't reflect the effect of material strain rate on the structure and the actual circumstances of undertaking the force distribution.
