本课题首次以旋流通风方式为研究主线，运用通风方程和示踪气体衰减理论设计实验方案，对旋流通风方式下普通会议室的速度、二氧化碳浓度进行了测试，分析了人员随意走动对浓度分布的影响，并调查了受试人员对各工况的主观评价。 | | 2. | 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 。 |
