用膨胀法测定了天然同位素丰度纯水在0 ~ 85 ℃、101 325 Pa压力下的热膨胀。获得以下等式:ρ(t)/ρmax = 1 - [(t -3,98152)2(t +396,18534)(t +32,28853)/609 628,6(t +83,12333)(t +30,24455)]其中ρ(t)是温度t时水的密度,用ITS-90表示,ρmax是最大密度。上述方程给出的密度比估计具有约1 × 10-6的不确定度。
The thermal expansion of pure water having natural isotopic abundance was determined by the dilatometric method in a temperature range from 0 to 85 °C and under a pressure of 101 325 Pa. The following equation was obtained: ρ(t)/ρmax = 1 - [(t - 3,98152)2 (t + 396,18534) (t + 32,28853)/609 628,6(t + 83,12333) (t + 30,24455)] where ρ(t) is the density of water at temperature t, which is expressed in terms of the ITS-90, and ρmax the maximum density. The density ratio which the above equation gives is estimated to have an uncertainty of approximately 1 × 10-6.
