摘　　要：研究了氢气经过流通式氘化铀床，利用气－固相之间的同位素交换反应回收床中的氘。用质谱分析测定交换过程中床内流出气体的各组分（Ｈ２，ＨＤ与Ｄ２）的体积百分含量。此外，还观察了床的入口氢气压力和床的温度对气－固交换反应的影响。结果表明：在优化条件下，从氘化铀床室温回收９８％的氘。Recovering deuterium from uranium deuteride bed by means of the isotopic exchange reaction between the solid and gas phases at room temperature is introduced. The mass spectrometric analysis with dividing time control sample is employed to measure the percentage concentration of the isotopic composition of gases existing from the uranium deuteride bed during the exchange process. In addition, the effect of temperature and input hydrogen pressure of bed on the gas solid exchange reaction are also examined experimentally. The results show that it is possible to recover 98% deuterium with more than 60% purity from the uranium deuteride bed under the proper condition and room temperature.
