Abstract：
The surface energy coefficient of nuclear matter σ( T,δ) is calculated, using the semi-infinite model of nuclear matter, as a function of temperature Tand nuclear asymmetry δby the temperature-dependent Thomas-Fermi statistical model theory, with the Seyler-Blanchard momentum-dependent nonlocal interaction. It is found that the surface energy coefficient can be written approximately as σ( T,δ)= σ ₀( T)[l+ K( T) δ ²], where the σ ₀( T) and K( T) can be fitted as quadratic functions of temperature T.
