Mechanical properties of QFP micro-joints soldered with lead-free solders using diode laser soldering technology HAN Zong-jie(韩宗杰)1, XUE Song-bai(薛松柏)1, WANG Jian-xin(王俭辛)1, ZHANG Xin(张 昕)1... carried out by means of diode laser soldering system with Sn-Ag-Cu and Sn-Cu-Ni lead-free solders, and competitive experiments were also carried out not only with Sn-Pb eutectic solders but also......
Optimal and suboptimal white noise smoothers for nonlinear stochastic systemsWANG Xiao-xu(王小旭), PAN Quan(潘泉), LIANG Yan(梁彦), CHENG Yong-mei(程咏梅)(College of Automation, Northwestern Polytechnical University, Xi’an 710072, China)Abstract:A new approach of smoothing the white noise for nonlinear stochastic system was proposed. Through presenting the Gaussian approximation about the white noise......
: The Sr1.93Ba0.05SiO4:Eu phosphors for white-light-emitting diodes were synthesized using low temperature combustion method. The influences of the amount of the flux SrCl2 and calcining temperature on the phase...; orthosilicate phosphor; light-emitting diode; luminescence properties 白光LED使用寿命长,效率高,节能环保,为21世纪重点发展的绿色照明光源[1].目前,产业化的白光LED制作方式是把蓝光LED管芯和黄色YAG:Ce3+微晶组合,管芯发出的蓝光一部分从微晶的空隙透出,其余部分经微晶转为宽带发射的黄光,二者叠加得到白光[2].然而,这种组合而成......
