| 摘 要： | 氚水在模拟水稻田中迁移，输运动态过程的研究表明，引入田水氚水，不仅在系统各隔室间转移和分配，而且也向系统外迅速地散逸，氚水的氚以自由水氚和结合态氚形式存在下水稻和土壤中，水稻地上部中自由水氚浓度开始增大，至第８天达最大值后便下降，而结合态氚基本上呈增中趋势，稻根中氚浓度低下地上部，表层土中二种形态氚随时间的变化与水稻植株中情况类似。

| Abstract: | The dynamic processes of movement and transportation of tritium water in simulated paddy have been investigated.Both free water tritium and bound tritium were found in the rice and the soil.The concentration of free tritium increased initially in the upper horizon of the soil and reduced after reaching the maximum at the 8th day.The bound tritium increased continu-ously.The tritium concentration in rice root was lower than those in upper ground portion. The variation in tritium concentration in surface soil were similar to those in plant. |
