摘　　要：将不同种类的毛发湿度计置于密闭湿度箱中,改变环境湿度,记录毛发湿度计湿度.研究结果表明在不同环境湿度下,在达到饱和响应时间之前毛发湿度计示数变化与时间有非线性关系.毛发湿度计对环境湿度响应速率在环境湿度条件下不一致,且响应速率在环境湿度较小时大于环境湿度较大时.The experiment was carried out in an airtight cabinet with different types of hair hygrometers inside.The humidity data were recorded by the hair hygrometers during the changes of humidity in the cabinet.The results showed that the humidity response curves of the hair hygrometers exposed to different ambient humidity were nonlinear before reaching the equilibrium.The humidity response speeds of the hair hygrometers were different at different ambient humidity,and the humidity response speeds in relatively lower humidity air was larger than that in relatively higher humidity air.

关 键 词：毛发湿度计 密闭湿度箱 环境湿度 非线性关系
