氚擴散 的英文怎麼說
中文拼音 [chuānkuòsǎn]
氚擴散
英文
tritium diffusion-
Aimed at the helium damages in plutonium caused by a decay, he + ions were implanted in aluminum and the behaviors of helium in aluminum were investigated both theoretically and experimentally to simulate those effects in plutonium. at the same time, the diffusion of helium - 3 produced by tritium decay in stainless steels, which were served as the structural materials in tritium and fusion technologies, was also investigated in this thesis
針對放射性元素鈈的衰變引起的氦損傷問題，選擇模擬材料鋁進行了he的離子注入和其中氦行為的理論和實驗研究，同時，也研究了氚工藝及聚變堆技術結構材料不銹鋼中氚衰變~ 3he的擴散行為，從而對兩種金屬中he的行為有了較深入的認識。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；對樣品表面逐層蝕刻、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、空氣中存放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部的局部區域，在整體趨勢上， ~ 3he分佈與計算結果相一致，根據理論計算，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 。
