Experiments on the separation of H-2-HD isotopic gas mixture were performed with a 1,020 mm-height "Cryogenic-Wall" thermal diffusion column with a heated tube of 9.63 mm-outer-radius and a cooled tube of 14.21 mm inner-radius which was cooled by liquid nitrogen. Abandance ratios of HD to H-2 in the feed, product and waste flow were measured by stable isotope mass spectrometer Finnigan MAT252.Our rigorous numerical code has predicted dependence of separation factors obtained experimentally upon the operating pressure fairly well.

在高1, 020 mm的“冷壁”热扩散柱上进行了分离H-2-HD同位素混合气体的实验，柱内加热管外径为9.63mm，冷却管内径为14.21mm，用液氮冷却。用Finnigan MAT 252稳定同位素质谱仪测量了进料、产物和废液中HD/H-2的废弃比。我们的严格数值计算程序很好地预测了实验获得的分离因子与操作压力的关系。
