摘　　要：介绍高膨胀比、大焓降、中小气量气体轴承透平膨胀机的两种流程设计方案:单级膨胀和两级膨胀,分析两种流程方案的优缺点,通过实例比较得出两级膨胀流程在膨胀机运行稳定性方面具有优势。Two design schemes of technical process of gas bearing turbine expander of high expansion ratio, big enthalpy drop and small-medium air flow rate （single-stage expansion and two-stage expansion） are briefed, and the advantages and disadvantages of two schemes of technical process are analyzed. The comparison of examples shows that the technical process of the two-stage expansion is superior in stable run of expander.
