根据流入与蒸发平衡状态下水的同位素比值，确定了60°和80°C时水蒸发的同位素分馏因子。在60°和80°C时，H2O/HDO的温度分别为1.0501±0.0029和1.0431±0.0022，H216O/H218O的温度分别为1.0176±0.0010和1.0156±0.0008。Oyunuma是日本同位素最重的地热池，相对于其大气流入，D/H分别富集40.3‰和16.5‰，可能是这种稳态蒸发盘的一个自然例子。
The isotopic fractionation factors in evaporation of water at 60° and 80°C were determined from the isotopic ratios of water under steady-state balance between inflow and evaporation. The results at 60° and 80°C are 1.0501 ± 0.0029 and 1.0431 ± 0.0022 for H2O/HDO and 1.0176 ± 0.0010 and 1.0156 ± 0.0008 for H216O/H218O, respectively. Oyunuma, isotopically the heaviest geothermal pond in Japan, is enriched by 40.3‰ in D/H and by 16.5 ‰ in 18O/16O, respectively, relative to its meteoric inflow and may be a natural example of such steady-state evaporation pans.
