提出了经典成核理论的公式，其中包括环境压力增加对过冷水中冰成核速率的影响。这种公式适用于描述在过冷水滴中观察到的均匀成核过程。根据成核理论的压力相关公式和现有的200-240 K温度范围内过冷水冰成核的实验数据，推导出冰水界面能。标准界面能参数化sigma(T) = sigma(0)(T/235.8)(n)，其中T为温度，单位为[K]，则得出sigma(0) = 23.24 +/- 1.10 mJ/m(2) 且 n = 0.35。 (C) 2013 Elsevier B.V. 保留所有权利。
A formulation of the classical nucleation theory is presented that includes the influence of an increased ambient pressure on the ice nucleation rate in supercooled water. Such formulation is suitable for the description of homogeneous nucleation processes observed in supercooled water droplets. The ice-water interfacial energy is deduced according to the pressure-dependent formulation of nucleation theory and the available experimental data of ice nucleation in supercooled water in the temperature range 200-240 K. The standard interfacial energy parametrization sigma(T) = sigma(0)(T/235.8)(n), where T is temperature in [K], results in sigma(0) = 23.24 +/- 1.10 mJ/m(2) and n = 0.35. (C) 2013 Elsevier B. V.
