On the Origin of Organic Molecules in Interstellar Space and Some of its Consequences,s cannot possibly explain the observed amounts of complex organic molecules. They are probably formed in interstellar clouds, either free in space or on the surface of grains. This opens the possibility that planets (also the earth) moving through such clouds may have collected appreciable amounts o作者: 枕墊 時(shí)間: 2025-3-22 05:15 作者: 一回合 時(shí)間: 2025-3-22 09:19

Organic Chemical Evolution of Reducing Model of the Atmosphere of the Primitive Earth. Role of UV L in the synthesis of organic compounds out of a reducing model of that atmosphere. Since Miller’s experiments in 1953, most of the experimental simulations have been performed with electric discharges, and it is frequently assumed that UV radiation would give similar results.作者: 一再遛 時(shí)間: 2025-3-23 15:28
