  1. The sense of this work is to gain a further understanding of helium in the two metals. on the diffusion of helium - 3 in two spherical shell samples made of 21 - 6 - 9 type of stainless steel, during the storage of tritium at the pressure of 6. 13mpa for about 4 and 6 years at room temperature and later exposed to air for another 3 and 1 year. first, a calculation based on the analytical and numerical method to the diffusion and decay theories was developed to evaluate the concentration distribution of helium - 3 by tritium diffusion and decay in the samples

    在不銹鋼氚衰變~ 3he的擴散行為研究中,建立了氚和~ 3he濃度分佈的解析解和數值計算方法,以評估充氚不銹鋼球形容器壁中氚衰變~ 3he的宏觀濃度分佈,同時還用數值計算方法以求解氚和~ 3he的多步擴散行為;對樣品表面逐層刻、同時收集釋放的~ 3he進行分析,分別實測了經室溫條件下在6 . 13mpa高壓氚中貯存4年和6年、氣中存放3年和1年的兩種21 - 6 - 9不銹鋼球殼樣品內壁中~ 3he濃度分佈;結果表明:由於he在金屬中的不可容性, he原子偏聚于不銹鋼表面以及內的局區域,在整體趨勢上, ~ 3he分佈與計算結果相一致,據理論計算,兩種21 - 6 - 9不銹鋼球殼樣品內壁中~ 3he到達的深度分別為350 m及500 m 。
