摘　　要：本文采用理论分析和数值计算的方法,确认由过增元教授等提出的强化换热的场协同理论同样可以应用到能量转换过程。文中用场协同理论揭示了脉管制冷机发展过程中几次重大改进的实质,并以此理论指导改进脉管制冷机的结构参数,发现了脉管的最佳长径比。It is found in this paper that the field synergy principle proposed by Guo and his co-workers for enhancing convective heat transfer is also applicable to the analysis of pulse tube refrigerator(PTR) performance. The several important improvements in the development of PTR can be well explained by the field synergy principle. Based on this principle, the optimum length over diameter ratio of the pulse tube was found by numerical simulation.
