neutrino mass造句怎么写

The main parts of this dissertation include three topics on different aspects of neutrino oscillation and neutrino masses.

The neutrino mass, which plays an important part in particle physics, cosmology and astrophysics, was a problem unsolved at the end of the 20th century.

Now the standard picture of neutrino masses and mixing is three neutrinos with sub-eV masses and bi-large mixing.
