涂料层高温透气性是气化模铸造涂料最重要的性能指标之一。本文介绍了一种能较准确测量透气性的方法，即使恒压下的压缩空气通过试样，测定不同温度下的气体的流量，经换算而得透气性数值。

The high temperature permeability of the coating material is one of the most important working properties. In this paper

a simple but accurate method is introduced. When the compressed air is passing through the sample with constant pressure

the flow of gas is measured atdifferent tempratures during the burning and escaping of the evaporative pattern

then

the permeability value can be obtained by conversion.
