用双克努森细胞质谱仪测定了1473~1673K下含磷0.20~0.92%的碳饱和铁水中磷的蒸汽压。在碳饱和的铁水中，磷在成分范围内符合亨利定律。在此条件下，磷相对于无限稀溶液的活度系数FP和铁水中碳与磷的相互作用参数e‘P C分别为：logfp=-300T+0.82(±0.05)，e’PC=120T+0.061(±0.010)。
The vapor pressure of phosphorus in molten carbon-saturated iron with phosphorus content of 0.20-0.92 mass% at 1 473-1 673 K was measured by double Knudsen cell mass spectrometry. In the molten carbon-saturated iron, phosphorus behaved according to Henry's law in the composition range. The activity coefficient of phosphorus in this conditions relative to infinite dilute solution, fp, and the interaction parameter of carbon on phosphorus in molten iron, e' p C , were determined to be as follows: log f p = - 300 T + 0.82(± 0.05), e' P C = 120 T + 0.061(± 0.010).
