| 摘 要： | 采用“单粒柱”新技术，测定了水蒸汽在粒状调湿剂中的有效扩散系数。以不同粒度、不同种类载气、不同吹扫气速进行测定，结果一致。表明：水蒸汽在粒状调湿剂中的扩散为粒子内扩散控制。以本法测定和对比了不同调湿剂中水蒸汽的有效扩散系数。

| Abstract: | A new technique was developed for the measurement of diffusivity of water vapor in humidity controlling agent.Consistency of diffusivities measured from different sample,different carrier gas and different purge flow rate were observed. Different diffusivities of different humidity controlling agent were measured and compared. |
