【摘要】 <正> 在制造氚容器、氚操作系统(如手套箱)的材料中,弹性材料和聚合材料是十分重要,而且几乎是不可缺少的材料。例如,各种橡胶、塑料和密封用的粘接材料都广泛应用于制造手套、垫圈、维修用帐篷以及氚防护服等。氚在这些材料中的渗透率一般都比在金属中更多还原

【Abstract】 The permeability of tritium in some elastomeric and polymeric materials aredetermined at two different temperatures using the method of measuringradioactivity of tritium which permeats through a membrane. The diffusivity andsolubility are obtained from dynamic curves clescribing permeation process. Resultsshow that the effect of temperature on permeability is remarkable. Comparisonwith literature values is made.更多还原
