摘　　要：The search for room-temperature superconductivity has been one of the great challenges in condensedmatter physics ever since the first observation of superconductivity with a critical temperature(T_(c))of 4 K in mercury in 1911.In recent years,we have been witness to the successful observation of superconductivity in highly compressed SH_(3)(T_(c)=203 K at 155 GPa)and classes of clathrate hydrides(e.g.,CaH_(6),YH_(6),YH_(9),LaH_(10)).
