本文提出了一个论点，它表明，如果g是临界等温线的度数，d是共存曲线的度数，f是当接近临界点时等温压缩系数变为无穷大的Δ Tc-T Δ-1的幂，则g=1+fd。讨论了这一结果与其他理论和实验事实的关系。
An argument is presented which indicates that if g is the degree of the critical isotherm, d the degree of the coexistence curve, and f the power of ∥ Tc—T ∥—1 with which the isothermal compressibility becomes infinite as the critical point is approached, then g=1+fd. The relation of this result to other theoretical and experimental facts is discussed.
