A Monte Carlo (MC) study is performed to evaluate the surface tensionof spherical membranes that may be regarded as the models of the lipid layers. We use the canonical surface model defined on the self-avoiding triangulated lattices. The surface tensionis calculated by keeping the total surface areaAconstant during the MC simulations. In the evaluation of, we useAinstead of the projected area, which is unknown due to the fluctuation of the spherical surface without boundary. The pressure differencebetween the inner and the outer sides of the surface is also calculated by maintaining the enclosed volume constant. Usingand the Laplace formula, we obtain the tension, which is considered to be equal to the frame tensionconjugate to, and check whether or notis consistent with. We find reasonable consistency betweenandin the region of sufficiently large bending rigidityor sufficiently largeA/N. It is also found thatbecomes constant in the limit ofboth in the tethered and fluid surfaces.
