摘要: Abstract Two models of the low temperature condensation accretion process for different extreme assumptions are investigated. In one time scale is taken to be long compared cooling nebula: in this case detailed chemical equilibrium maintained at all temperatures, and characterized by solid hydrates such as NH3·H2O CH4·8H2O. opposite extreme, assumed rapid cooling: here condensates, once formed, isolated from further interaction with gas. This inhomogeneous model closely analogous sequences solar-composition planetary atmospheres, formation aqueous NH3 solution, NH4SH, NH3. The results these their relevance processes solar nebula discussed.
