Design of Tokamak ELM Coil Support in High Nuclear Heat Environment

In Tokomak, the support of the ELM coil, which is close to the plasma and subject to high radiation level, high temperature and high magnetic field, is used to transport and bear the thermal load due to thermal expansion and the alternating electromagnetic force generated by high magnetic field and AC current in the coil. According to the feature of ITER ELM coil, the mechanical performance of rigid and flexible supports under different high nuclear heat levels is studied. Results show that flexible supports have more excellent performance in high nuclear heat condition than rigid supports. Concerning thermal and electromagnetic （EM） loads, optimized results further prove that flexible supports have better mechanical performance than rigid ones. Through these studies, reasonable support design can be provided for the ELM coils or similar coils in Tokamak based on the nuclear heat level.     

酸性玫红BB的萃取平衡特性研究

以酸性玫红BB为研究对象,探讨了三辛胺(TOA)萃取水中酸性染料的萃取平衡特性,结果表明:(1)在一定三辛胺含量条件下,随水相中染料质量浓度的增大,体系的萃取平衡系数出现明显的上升,说明在所研究的质量浓度范围内,本体系有利于萃取高质量浓度的染料废水;(2)在所研究的染料质量浓度范围内,在有机相内形成染料分子-TOA一对二的可能性是存在的,即TOA与染料分子的结合方式应以1∶1和1∶2为主.当有机相中染料分子较多时,部分1∶2结构解离,释放出部分三辛胺,因此在高质量浓度下,油相的吸附能力增大,表现为分配系数有增大的趋势;(3)获得的萃取相平衡曲线可以用于选择萃取条件的工程设计.
