【摘要】 同位素分离中可能需要具有多个供料和取料的级联,以满足复杂的分离需求,取得更好的分离效果。对多供取料级联的分析,比传统三股流级联的分析复杂得多。获得多供取料下的级联数学描述,能够减少分析中的困难。本文针对多分段的连续流量的Q模型级联,在多供取料情况下,给出了描述级联的流量和同位素组分丰度在级联中分布的解析表达式,讨论了方程的求解和级联优化的原则。更多还原

【Abstract】 There are possibilities of using cascades with multiple feeds and withdrawals to meet the needs of complicated separation tasks for a better separation results. The analysis of cascades with multiple feeds and withdrawals is much more difficult than conventional three-stream cascades. The difficulties can be greatly mitigated if an analytical mathematical description is provided. For multiply sectioned Q-model cascade of continuous profile with multiple feeds and withdrawals, the equations describing the distributions of cascade flows and component concentrations are derived. The solution of the equations and optimization of cascade are discussed.更多还原
