helium-3 meaning in English
氦3
Examples
- Nuclear energy . nuclear fuel cycle technology - waste - non - intrusive , non - destructive determination of the tritium activity of a package containing tritiated waste by measurement of helium - 3 leakage from the package
核能.核燃料循环技术.废弃物.通过从封壳里泄露出来的氦- 3的测量对含氚废弃物封壳的氚放射性进行非侵入和非破坏性测量 - This is due to the incompatibility of helium with the matrix atoms . but on the whole , the trend of helium distri bution by the determination was similar to that by calculation . and the depth which helium - 3 could reach in both samples were 350 microns and 500 microns respectively
在金属铝中氦行为的理论研究中，基于密度泛函理论、广义梯度近似、赝势平面波方法，计算了单个he原子在金属铝中的各种能量数据，包括各种he原子-缺陷的形成能、迁移能、束缚能以及离解能数据。 - 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
在不锈钢氚衰变~ 3he的扩散行为研究中，建立了氚和~ 3he浓度分布的解析解和数值计算方法，以评估充氚不锈钢球形容器壁中氚衰变~ 3he的宏观浓度分布，同时还用数值计算方法以求解氚和~ 3he的多步扩散行为；对样品表面逐层蚀刻、同时收集释放的~ 3he进行分析，分别实测了经室温条件下在6 . 13mpa高压氚中贮存4年和6年、空气中存放3年和1年的两种21 - 6 - 9不锈钢球壳样品内壁中~ 3he浓度分布；结果表明：由于he在金属中的不可容性， he原子偏聚于不锈钢表面以及内部的局部区域，在整体趋势上， ~ 3he分布与计算结果相一致，根据理论计算，两种21 - 6 - 9不锈钢球壳样品内壁中~ 3he到达的深度分别为350 m及500 m 。 - 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
针对放射性元素钚的衰变引起的氦损伤问题，选择模拟材料铝进行了he的离子注入和其中氦行为的理论和实验研究，同时，也研究了氚工艺及聚变堆技术结构材料不锈钢中氚衰变~ 3he的扩散行为，从而对两种金属中he的行为有了较深入的认识。
