Abstract：
Based on Weinberg-Salam theory the bremsstrahlung neutrino energy loss for nuclei ²⁴Mg, ²⁸Si, ³²S, ⁴⁰Ca and ⁵⁶Fe 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 10⁸ g/cm³≤ρ/μ_e≤10¹¹ g/cm³ and 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 nuclei ²⁴Mg, ²⁸Si, ³²S, ⁴⁰Ca and ⁵⁶Fe.
