摘　　要：以氚水为示踪剂，测定了氚在有机相和水相间的分配比。给出了以分配比计算水在有机溶剂中的溶解度的关系式。据此，测定了水在几种常见溶剂中的溶解度，并测定了不同浓度的ＴＢＰ／煤油中水的溶解度，得到了水的溶解度与ＴＢＰ浓度的关系式。Using tritited water as tracer, the distribution ratios of tritium between organic phase and aqueous phase are determinated. The relative formula for counting the solubility is presented directly from the definiens of distribution ratio. Accordingly, aqueous solubilities in some of common solvents as well as tributyl phosphate/kerosene in various concentration are also determinated. The relationship between aqueous solubility and concentration of tributyl phosphate can be written as ρ O(H 2O) =63 φ 1 8 (TBP) 
