摘　　要：Superconductivity—the phenomenon of complete vanishing of electrical resistance and expulsion of magnetic field—is the paramount electromagnetic property for technological advancement that is only shackled by the requirement for an extremely low superconducting critical temperature(T_(c)).The discovery of a T_(c) of>200 K in hydrogen sulfide at 200 GPa of pressure[1]broke the 20-year high-T_(c) record of 164 K in mercury cuprate at 30 GPa,and stimulated tremendous interest in the scientific community.
