University, Changsha 410082, China; 3. College of Mechatronics and Control Engineering, Shenzhen University, Shenzhen 518060, China) Abstract: The deformation modes and energy absorption capacity of Al-Mg... at 180 ℃ from 30 min to 540 min. The results indicate that the deformation mode of the aluminum extrusions is gradually changed from diamond mode to concertina mode and the energy absorption......
performed.Experimental absorption spectra were measured at room temperature and assigned.The first principles discrete variational multielectron method was used to model the polarized absorption spectra of the Ca4GdO(BO3)3:Pr3+;without any fitting parameters,the overall appearance of the spectra was reproduced satisfactorily.The energy intervals between different molecular orbitals in the [PrO6]cluster were......

Energy Transfer from PVK to Europium Complex in Electroluminescence 白峰1,王振家1,韩建民1,刘舒曼1,张希清1,高新1,陈晓红1,邓振波1 (1.Institute of Optoelectronic Technology, Northern Jiaotong University, Beijing 100044, China) Abstract:The spectra of solutions, films and light-emitting diodes of rare earth complexes were studied. It is shown that the absorption spectra of PVK-dopping rare earth complexes can be red......
. There is an abrupt reduction when the energy is a little higher than 13.762 eV, which corresponds to the peak of electron energy loss spectrum (EELS). The absorption coefficient is as large as 105 cm-1, and the absorption mainly locates in the low energy region.
