摘 要 ：利用同位素示踪技术研究了进入水体的ＨＴＯ向陆地的迁移。结果表明：１．进入水体的ＨＴＯ将向系统各组分转移，池水中的ＨＴＯ单调地减少，底泥及水生生物中的ＨＴＯ浓度皆在经历某一最大值后平缓地下降；２．ＨＴＯ中的而以自由水沉和结合态氚存在于水生动植物和底泥中；３．ＨＴＯ还明显地向毗邻的陆地和作物迁移，在一个半月期间，陆地系统中的总而约占水体的２４％。

Abstract:he isotope tracer techniques are applied to explore the transfer of HTO from waterbody to land.The results show that when HTO entered a water body,it would transfer toother compartments in the ecosystem,and HTO in the water phase showed a monotonous de-crease with time。However the concentration of HTO in either sediment or aquatic life was in-creased to a peak in a period and then declined gently.Tritium of HTO present in sedimentand aquatic life is in two forms,i.e.,tritium in free water and bounded tritiu...
