摘要: A review is presented of current theories nucleosynthesis. The predicted contributions from (1) cosmological nucleosynthesis, (2) super-massive stars, (3) non-violent (quasi-static) stellar evolution, (4) supernova explosions, (5) cosmic ray interactions with the interstellar medium and (6) nova explosions to observed solar system abundances are summarized. Recent studies ‘explosive nucleosynthesis’ in supernovae production lithium, beryllium boron by interaction rays gas emphasized. Observations spectra which either impose limitations upon or provide confirmation various aspects these noted, as several critical nuclear experiments. general picture emerges incouraging that most major abundance features appear be at least qualitatively understood, but significant further research required.
