摘要：
Direct extrapolation of the strong interaction between quarks in pure perturbative calculation has a problem of thermodynamic inconsistency. A new term determined by thermodynamic consistency requirement could resolve it. This new term plays an important role at lower density in describing the equation of state of quark matter, while it is negligible at high density. Accordingly, the density behavior of the sound velocity becomes more reasonable, and the maximum mass of quark stars can be as large as two times the solar mass.
