| 释义 | > as lemmasmass-energy mass-energy n. Physics mass and energy considered as interconvertible manifestations of the same property, related by the equation E=mc2 (propounded by Einstein in Ann. der Physik (1905) 18 641), where E is the energy equivalent of a mass m and c is the speed of light; the mass of a body regarded relativistically as energy.
