Abstract
It is found that the radius for a stable strangelet is a decreasing function of temperature in quark mass density- dependent model. To overcome this difficulty, we extend this model to quark mass density- and temperature- dependent model in which the vacuum energy density at zero baryon density limit B depends on temperature. An ansatz B=B 01-a(T/T c )+b(T/T c ) 2 is introduced and the regions for the best choice of the parameters are studied.
