摘 要: 根据福建 2 2个主要树种的红外光谱特性 ,选择波长为 5 .43μm远红外辐射作实验 ,获得了反映木材对远红外吸收的实验规律的一个普遍公式 .根据该公式得到了透过率分别为 1 /1 0 0、1 /1 0、 1 /e的穿透深度 ,发现穿透率为 1 /e的穿透深度与细胞腔的尺度同一数量级 。 On the basis of specific property of far infrared spectra of 22 major tree species of Fujian,the far infrared radiation of wavelength 5 43 μm was chose for experiment,a general formula of the law of experiment of wood absorbed far infrared was obtained According to the formula,we obtained the depth of penetration of transmittance in 1/100,1/10,1/e,and discovered that the depth of penetration of transmittance in 1/e is the same size as the cell of wood It expains the viewpoint that the cell is basic unit absorbing the infrared radiation
