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 T and nuclear asymmetry δ by 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)=σ₀(T)[l+K(T)δ²], where the σ₀(T) and K(T) can be fitted as quadratic functions of temperature T.
