Abstract：

Based on Weinberg-Salam theory the bremsstrahlung neutrino energy loss for nuclei²⁴Mg,²⁸Si,³²S,⁴⁰Ca and⁵⁶Fe are investigated in strong electron screening. Our results are compared with those of Dicus' and show that the latter are higher by 2 orders of magnitude in the density-temperature region of 10⁸g/cm³≤ρ/μ_e≤10¹¹g/cm³and 2.5≤T₉≤4.5. On the other hand, the factor C shows that the maximum differences are 99.16%, 99.13%, 99.12%, 99.055%, 99.040% corresponding to the nuclei²⁴Mg,²⁸Si,³²S,⁴⁰Ca and⁵⁶Fe.
