放射性同位素热电发生器的退役

国际原子能机构通报 2006年第2期 42-47页

作者： malgorzata K.Sneve 挪威厄斯特罗地区挪威辐射防护管理局

数百个旧的大放射源在俄罗斯西北海岸线星罗棋布。这些被称为放射性同位素热电发生器的源,主要为遥远的灯塔供电。现在这些供电组件正在被安全地拆除。挪威在帮助俄罗斯完成这项任务。

介绍了连续增强铸造铝基复合材料的性能及其制造过程。该工艺能获得一种在某些应用场合中性能优于可热处理的铝合金或聚合复合材料的结构材料。检验得到的热物理性能和结构特征,包括材料的各向异性以及以前Al2O3增强纤维及金属预浸料坯力学性能的测定结果都证明了该材料的高质量及其在特定的载荷模式和环境条件下工作的可能性。显微观察(光学显微镜,扫描电子显微镜)显示了微观组织的形态均匀性范围,纤维带分布的各向异性,以及金属/纤维界面的粘着特性。用计算机层析X射线照相法来显示所选取的微观组织组元的三维形态。结果表明:预浸料坯的特殊性能一方面受到其内在的微观组织几何形态,即Al2O3增强纤维体积分数和空间分布的强烈影响,另一方面还受到金属预浸料坯的各组元之间达到非常好的相容性的强烈影响。

为掌握中国油菜品种的黑胫病抗性水平，为抗病育种及品种合理布局提供理论依据。在室内采用子叶穿刺接种法，对35个油菜品种开展了黑胫病的抗性评价及抗病基因推导研究。供试品种中没有发现对病原菌 Lepto-sphaeria maculans 和 Leptosphaeria biglobosa 表现高抗或免疫的品种，只有3个品种可以兼抗 Leptosphaeria maculans 和Leptosphaeria biglobosa，但均表现低抗。供试的35个品种对12个菌株共产生了17种反应型，其中12个品种的反应型与鉴别寄主的完全相同，18个品种的反应型与鉴别寄主的非常相近，5个品种的反应型不同于任何鉴别寄主。抗病基因推导，已知的12个黑胫病抗性基因 Rlm1～9，Lep R1～3多数以基因组合的形式分布在我国的30个品种中，这些主栽品种可能含有已知的或新的抗病基因。说明现有的油菜种质资源中可能蕴藏着对改良黑胫病抗性具有潜在应用价值的基因资源。

利用微卫星(SSR)标记,分析来自欧洲和中国的30个核盘菌菌株的遗传多样性和群体结构。结果表明,3对微卫星引物共扩增出21条清晰的谱带,平均每对引物扩增7条谱带,片段长度为158bp～358bp。根据SSR分析结果,30个核盘菌分离物具有较高的遗传相似性。物种水平的Nei遗传多样性指数为0.139 3,Shannon多样性指数为0.248 8。不同菌株群体的Nei遗传距离都较小,为0.009 6～0.049 6。其中俄罗斯群体和奥地利及英国群体之间的遗传距离最大。从30个菌株的UPGMA聚类分析结果看,核盘菌群体结构与地理来源没有明显的直接关系。许多地理来源相同的菌株分散在不同的组里。仅第三组组内的菌株地理来源一致,均来自于中国,且遗传距离比其他菌株的远。群体遗传分析显示,总群体的基因流比较高(2.111 6),基因分化系数比较低(0.191 5)。
