    Precise positioning of the Chang’E-3 lunar lander using a kinematic statistical method

    A kinematic statistical method is proposed to determine the position for Chang’E-3 (CE-3) lunar lander. This method uses both ranging and VLBI measurements to the lander for a continuous arc, combing with prec...

    Shock wave compression of poled Pb0.99[(Zr0.90Sn0.10)0.96Ti0.04]0.98Nb0.02O3 ceramics: Depoling currents in axial and normal modes

    We used a 100-mm diameter gas gun to investigate the output currents due to the sudden depolarization of poled Pb0.99-[(Zr0.90Sn0.10)0.96Ti0.04]0.98Nb0.02O3 ceramics under shock wave compression. We conducted sho...
