为了弄清楚在水蒸气流入流出过程中木质室内装饰材料对环境湿度的调节规律，定量评价室内装饰材料的环境湿度调节性能，该研究在环境恒定温度为２６ ℃条件下，测定了在水蒸气流入流出过程中木质及非木质材料装饰的试验体内环境湿度的经时变化规律，在此基础上定义了ｘ 和ｙ 两个参数来表征材料对环境湿度的调节性能。研究结果表明：（１） 用ｘ 和ｙ 值能够将各种材料按其调湿性能分成４ 个组别。（２） 木质材料类具有较好的环境湿度调节性能，即这些材料能够缓和室内环境湿度的急骤变化。（３） 木质材料的ｘ 和ｙ 值随气积比 Ａ／ Ｖ 的增大呈曲线下降趋势。（４） 在本实验设定的循环过程中，材料厚度对其调湿性能影响不显著。
In order to clarify the regulation rules of environmental humidity of wood interior decoration materials in the course of water vapor inflow and outflow, quantitatively evaluate the environmental humidity conditioning performance of interior decoration materials. This study measures the flow of water vapor at a constant ambient temperature of 26 °C. During the outflow process, the time-varying laws of the environmental humidity in the test of wood and non-wood materials were determined. On this basis, two parameters, x and y, were defined to characterize the adjustment performance of the material to the environmental humidity. The results of the study show that: (1) The x and y values can be used to classify various materials into four groups based on their humidity control performance. (2) Wood materials have good environmental humidity control properties, that is, these materials can ease sudden changes in the indoor environment humidity. (3) The x- and y-values of wood materials show a downward curve as the air volume ratio A/V increases. (4) In the cycle set in this experiment, the thickness of the material has no significant effect on its humidity control performance.
