聚变堆包层流动锂液帘与堆芯兼容性评估

运用零维模型分析了液态锂作为包层流动液帘与堆芯等离子体的兼容性,得到了液态锂工作温度对堆芯有效平均等离子体电荷Zeff、燃料稀释以及聚变功率之间的关系。结果表明在正常工作情况下,液态锂的蒸发对Zeff的影响不是很严重,但对燃料稀释和聚变功率的影响却较为敏感。在具有较高功率密度的反剪切位形聚变实验增殖堆FEB E设计方案Ⅱ的条件下,计算了液态锂的流速与它表面最大温升的关系,结果表明,即便对0.5m·s-1的低速流动液态锂,其蒸发对聚变等离子体的影响甚微。最后对氢同位素饱和状态下液态锂包层表面的溅射作了初步的讨论。

CZE-ESI-MS联用测定小肽混合物的研究

CZE ESI MS is one of the most sensitive detection method and one of the potential method for protomics analysis. In this work, peptide mixture was separated and detected by using CZE ESI MS, and the influence of pH value of buffer and composition of sheath liquid on CE separation and MS detection was investigated. The method allows the detection limits up to 4 2—33 pg. The result of this method is better than that of CE UV for the peptide analysis.
