五、木材表里传热机理本章着重阐明由热辐射源发射的主辐射波长为3—15微米的红外线加热木材其内部的温度分布规律。对较厚木材,在加热升温期间,其内部的温度始终是低于它边缘的温度。 1.基本关系在“红外线对木材的穿透深度”一章中,曾较详细地论述了当远红外线进入木材后,其辐射能量与进入深度的关系服从布格尔一兰柏(Bouguer-Lambert)定律,此外,文中还指出木材对远红外线的吸收系数
Fifth, the heat transfer mechanism in the wood table This chapter focuses on the infrared radiation emitted by the heat radiation source of the main radiation wavelength of 3-15 microns infrared wood temperature distribution within the law. For thicker wood, the temperature inside is always lower than the temperature of its edge during heating. 1. BASIC RELATIONS In the chapter “Infrared penetration depth into wood,” it has been discussed in more detail that when far-infrared rays enter the wood, the relationship between radiant energy and penetration depth follows Bouguer-Lambert ) Law, in addition, the paper also pointed out the absorption coefficient of wood to far infrared rays
