摘要
脉管在脉管制冷机中所起的作用,主要体现在热力学和动力学两方面。由热力学平衡计算可决定脉管制冷机的尺寸,但同时也要进行动力学上的匹配。着重利用Dr.deBoer的热力学分析方法对脉管内的气柱位移进行了定量计算 ,给出了计算结果 。
The role of the pulse tube in PTR system is twosided, namely thethermodynamic and the dynamic.The thermodynamic aspect determines the refrigeration mechanism of the pulse tube, which in turn exerts dynamic influence on PTR system. The method proposed by Dr. de Boer has been used to investigate the displacement of the gas in the pulse tube of a PTR system. The computational result and the discussion on it are presentedhere.
