中文摘要：

针对一种新型的组合型线的涡旋压缩机，系统地研究了该型线的压缩机各个压缩腔行程容积的求法，使得各个压缩腔随着曲柄转角的变化在不同段曲线的容积可以清楚的求出，为准确计算该型线的压缩机动力学及性能指标提供了依据。

英文摘要：

Aimed at a new type scroll compressor of the combination profile, this paper analyzes the detailed rule of the each working dimension. With the changing of the scroll profile types, the different equation for the scroll chamber working process is set up. The fundamentals for calculating the kinematics and property of scroll compressor are given.
