提出了国际蒸汽性质协会所接受的轻水和重水临界参数的最可能值的建议,以及对其可靠性的评估。结果为,对于H2O:Tc=(647.14+δ1)K,δ1=0.00±0.10; Pc=(22.064+0.27δ1±0.005)MPa; ρc=(322±3)kg/m3;对于D2O:Tc=(643.89+δ2)K,δ2=0.00±0.20; Pc=(21.671+0.27δ2±0.010)MPa; ρc=(356±5)kg/m3。提供了这些值的选择及其可靠性评估的支持材料。除非另有说明,温度值采用 1968 年国际实用温标 (IPTS 1968)。
Recommendations for the most likely values of the critical parameters of light and heavy water as accepted by the International Association for the Properties of Steam are presented, together with an assessment of their reliability. The results are, for H2O: Tc=(647.14+δ1)K, δ1=0.00±0.10; Pc=(22.064+0.27δ1±0.005) MPa; ρc=(322±3) kg/m3; and for D2O: Tc=(643.89+δ2) K, δ2=0.00±0.20; Pc=(21.671+0.27 δ2±0.010) MPa; ρc=(356±5) kg/m3. Supporting material for these choices of values and the assessment of their reliability is provided. Temperature values are on the International Practical Temperature Scale of 1968 (IPTS 1968) unless otherwise indicated.
