本文提出了一种测定液体复合材料成型渗透率的统一方法。UA既适用于槽流实验，也适用于径向流实验，统一了几乎所有已知渗透率测量方法的数据处理。它允许根据在任意坐标系中进行的实验测量来计算主渗透率。本文介绍了UA及其主要特点。此外，将UA应用于径流和槽道流测量的大量实验结果，以验证其有效性。此外，根据UA对现有的渗透率测量方法进行了分类，并在必要时讨论了不同的方法。一些数据处理算法被发现存在弱点或缺点。
This paper presents a unified approach (UA) to determining permeability in liquid composite molding. The UA applies both to the channel flow and the radial flow experiment and it unifies the data processing of almost all known permeability measurement methods. It permits principal permeability to be calculated from experimental measurements which are carried out in an arbitrary co-ordinate system. This paper describes the UA and its main features. Further, the UA is applied to a number of experimental results for radial flow and channel flow measurements to demonstrate its validity. In addition, the algorithms of current permeability measurement methods are classified according to the UA, and, where necessary, differences are discussed. Some data processing algorithms were found to contain weaknesses or shortcomings.
