摘要：

The phase diagram in temperature-entropy space plays an important role in the visualization, design and analysis of operating cycles in refrigerators and heat pumps. The shape of the phase boundary in this space varies dramatically from one material to another. The origin of these differences is shown to be a consequence of molecular structure. Relationships of varying accuracy are developed to estimate the slope of the vapour branch of the T-S diagram.
