Abstract: In the late 1960s，U.S.astrophysicist Davis successfully detected the solar neutrino.However,the number of income was only about half of the standard solar model predictions.According to unified electro-weak theory,the neutrino has zero rest mass,which constitutes a paradox of solar neutrinos.Kam-Lan Experimental results showed that atmospheric neutrino oscillation did occur,and neutrinos did have rest mass.The follow-up sudbury experiments finally resolved the issue of neutrino paradox,making  people question unified electro-weak theory,think about their significance in particle physics as well as in astrophysics.Those objectively support the self-consistent logical positivism.

Key words: rest mass of neutrino, paradox of neutrinos, unified electro-weak theory, Hawking's positivism
