Peter Knabner,Lutz Angermannnal volatile inventory among neighboring planets (Morbidelli et al. 2000). However, given the great similarity in bulk densities and their close proximity in the Solar System the best assumption at present is that Venus and Earth started with similar water abundances.GONG 发表于 2025-3-25 11:05:52

sound images (Chaffaí et al. 2002; Haïat et al. 2007; Wear 2008). For example, Wear (2000) reported average backscatter coefficient to be 50 % higher in the medial-lateral (ML) direction than in the anterior-posterior (AP) direction (human calcaneus, 500 kHz).

Peter Knabner,Lutz Angermannwere similar. Although the two planets have similar overall abundances of nitrogen and carbon, the present day water inventory of Venus is lower than that of Earth by a factor of 10.. The original water abundance of Venus is highly unconstrained. The high D/H ratio observed, 2.5 ×10. or ≈ 150 times
