摘要：

We study the extension of a phenomenologically successful quasiparticle model that describes lattice results of the equation of state of the deconfined phase of QCD for T(c)less than or equal toTless than or similar to4T(c), to finite quark chemical potential mu. The phase boundary line T-c(mu), the pressure difference Deltap(T,mu)=[p(T,mu)-p(T,mu=0)]/T-4, and the quark number density n(q)(T,mu)/T-3 are calculated and compared to recent lattice results. Good agreement is found up to quark chemical potentials of order musimilar toT(c).
