For predicting the milling force in process of micromilling aluminum alloy,the law for micromilling force changing under different milling parameters was studie
A novel frequency synchronization scheme for orthogonal frequency division multiplexing(OFDM) systems is proposed,including a novel frequency offset estimation
The influences of copper on microstructure and the hardening behavior of high chromium cast irons subjected to sub-critical treatment were investigated.The resu
Nd3+doped lead zirconate titanate(Pb1-3x/2Nd,Zr0 52Ti0.48O3,PNZT)nanopowders were prepared through a modified sol-gel method.The effects of Nd3+doping on the mi
