Гендерные особенности структуры мотивации выбора экстремальных видов спорта

Single-phase perovskite ceramics were synthesized using a Pb-free (K(0.44)Na(0.52)Li(0.04))(Nb(0.86)Ta(0.10)Sb(0.04))O(3) (LF4) piezoelectric material both with and without CuO as a dopant additive. Bipolar hysteresis measurements showed a relatively high remanent polarization (20 μC/cm(2), 16 μC/cm... View More
