By combining accurate liquid-vapor coexistence and heat-capacity data, we have unambiguously separated two nonanalytical contributions of liquid-gas asymmetry in fluid criticality and showed the validity of "complete scaling" [Fisher, Phys. Rev. Lett. 85, 696 (2000)10.1103/PhysRevLett.85.696; Phys. Rev. E 67, 061506 (2003)10.1103/PhysRevE.67.061506]. We have also developed a method to obtain two scaling-field coefficients, responsible for the two sources of the asymmetry, from mean-field equations of state. Since the asymmetry effects are completely determined by Ising critical exponents, there is no practical need for a special renormalization-group theoretical treatment of asymmetric fluid criticality.
通过结合精确的液-气共存和热容量数据，我们明确地分离了流体临界性中液-气不对称的两种非解析贡献，并证明了“完全标度”的有效性[费舍尔，《物理评论快报》85, 696 (2000)10.1103/PhysRevLett.85.696；《物理评论E》67, 061506 (2003)10.1103/PhysRevE.67.061506]。我们还开发了一种方法，从平均场状态方程中获得负责两种不对称源的两个标度场系数。由于不对称效应完全由伊辛临界指数决定，因此实际上无需对不对称流体临界性进行特殊的重整化群理论处理。
