Mn2+ may occupy Ca2 site (Mn2+(I)) to generate a yellow emission band at 574 nm or Sc3 site (Mn2+(II)) with red emission band at 680 nm. Efficient energy transfers from the green emitting Ce3+ to both Mn2+(I) and Mn2+(II) occur upon blue excitation into Ce3+. Concentration dependence of Mn2+ emission is analyzed based on Ce3+-Mn2+ energy transfer  steady state rate equations  and fluorescence lifetimes. Energy transfer efficiency (nT) and rate (W) are calculated with values as high as 45% and 14.01106 s-1  respectively. 2011 Elsevier B.V.   ACTIVATION OF A 250 MEV SC-CYCLOTRON FOR PROTON THERAPY 研究报告  OAI收割 2010 G.

The design  hardware structure  a target detecting method and software char flow of FPGA and DSP are presented. The system is tested by a 1Kx1K image  the processing time is 1.3ms  experiments results show that the method is feasible  the simple design and stable correct results make this method very ascendant in practical application. 2010 IEEE.   德国蜚蠊精母细胞联会复合体（SCs）租型及辐射诱发的SCs畸变 期刊论文  OAI收割 遗传学报, 1986, 卷号: 13, 期号: 5, 页码: 377-382 作者:  冯蜀举;  施立明   |  收藏  |  浏览/下载：17/0  |  提交时间：2010/07/27 联会复合体  Sc_s  组型  减数分裂前期  精母细胞  银染色
