摘　　要：本文对非共沸工质R407C在毛细管中的流动特性进行了系统的研究。通过能量、动量、质量方程,分别就过冷区和两相区作了理论求解,并将计算结果全部绘制成了曲线。In this article the flowing characteristic of non - azeotropic refrigerant R407 in capillary tube was systematically studied. The calculation for the subcooling zone and the two - phase zone before the capillary tube was accomplished respectively through the equations of energy,mass and momentum. All the results were shown in the figures with curves.
