求英文摘要润色。

中文：本文建立了一个用于分析不同级间结构的双级压缩系统性能的通用模型。该模型基于一个典型的再冷循环推导得出，并通过“输入域”扩展到其它循环。输入域通过一个以过冷参数为x坐标，以高压机吸气焓值和喷射制冷剂焓值为y坐标的图形来表示，很好的展示了文中所选的八种级间结构之间的差异及关联。一些典型例子的计算结果表明，该模型可以用于各种循环之间的性能分析比较，制冷剂选择及系统运行分析。通过附加计算蒸发压力、冷凝压力以及（或）过冷参数，该通用模型可以扩展到其它详细的形式。
英文：This paper presents a general model suitable for analyzing performance of a two-stage vapor compression heat pump system with different types of inter-stage configurations. The general model is derived from a typical subcooler cycle, and then generalized to other cycles by employing an “input domain”. The “input domain” is presented with a figure that employs an inter-stage subcooling parameter as the x-axis and the high-stage compressor suction refrigerant specific enthalpy and the injection refrigerant specific enthalpy as the y-axis, which provides well understanding of the differences and relations among the selected eight types of inter-stage configurations. The modeling results of some typical examples show that, the general model is capable of performance comparison among different types of cycles, refrigerant selection or operational analysis. With additional calculations of the subcooling parameter, evaporating and/or condensing pressure, the general model can be extended to other detailed forms.
