摘要

The in-medium quark condensate is studied with an equivalent-mass approach in which one does not need to make assumptions on the derivatives of model parameters with respect to the quark current mass. It is shown that the condensate is generally a decreasing function of both the density and temperature with the decreasing speed depending on the confinement parameter. Specially, at given density, the condensate decreases on increasing temperature. The decreasing speed is comparatively small at lower temperature, and becomes very fast at higher temperature.
