采用测色色差计对中国110种商品材树种的木材表面材色参数进行测量，讨论了这些参数的色空间分布特征，其结果（除去一个黑颜色树种乌木）为：明度指数分布范围较宽（L*为30～90；V为2～8），色品指数和色调值参数分布范围较窄（a*为-2～20；b*为0～30；H为2.5R～5Y，大部分分布在YR色调系内），饱和度分布范围不宽（C*为4～6；C为0.8～6.4）。其中针叶树材分布范围较窄，且多分布在高明度范围，并对110树种的木材表面光泽度（镜面反射60°）分顺纹理和垂直纹理两个方向进行了测量和分布特征解析。无涂饰木材表面镜面反射光泽度较低，大多分布于10%以下的范围，分布中心在5%左右。顺纹理入射与垂直纹理入射条件下的光泽度相比，前者较大，两者之间具有高度的相关性，其关系可用线性方程式表达。

It is commonly known that the mechanism of fire retardancy of boric acid is by forming a coating or protective layer on wood surface at high temperature. However, this mechanism could not explain the phenomena in our previous work, in which boric acid influenced the pyrolysis of wood at much lower temperature. To understand better the fire retarding mechanism of boric acid on wood, in this paper the effect of boric acid on the pyrolysis and fire retardancy of wood was studied by thermal analysis and cone calorimetry (CONE). Basswood (Tilia amurensis Rupr.) was treated with boric acid, guanylurea phosphate (GUP) and GUP boric acid respectively. The treated woods were analyzed by thermogravimetry (TG/DTG), differential thermal analysis (DTA) and by CONE. It was found in TG that the weight loss of boric acid treated basswood was about 3 times of GUP treated wood or untreated wood at 165℃, the temperature at which GUP is stable. The DTA curve showed that boric acid treated basswood has an exothermal peak at 420℃, indicating the exothermal polymerization reaction of charring. The CONE result showed that boric acid and GUP had considerable synergistic fire retardant effect on wood. It is concluded that boric acid has fire retardant effect on wood through mechanisms other than coating or protective layer, it has different effects in the different stages of the combustion of wood, it catalysts the dehydration and decomposition of wood and promotes the charring of wood. The fire retardant synergism of boric acid and GUP is due to their functioning by different mechanisms.

随着人类的进步和生态学的发展，正在兴起“生物圈规划”和“人与生物圈”的研究，冲击着传统的木材科学研究领域，逐渐增加了与生态和环境科学有关的研究内容，进而形成了木材科学的一个重要分支--生物木材科学。它是以木材性质分析为基础，以生物学、林学和环境学为关联学科，侧重研究林木在不同生态环境中木材形成与材质的分析、经营技术与材质的关系、生态环境与材质变异的关系、林木与人类生存的关系、幼龄材与成熟材的界定及材质早期预测等等，进而揭示生物学、林学、环境学与木材材性的关系，为搞好集约经营，优化林木材质，发挥林木的多功能、多效益和保护环境，提高木材品质，改善人类生活质量等均具有重要意义。木材、人类和环境的关系及合理利用森林与生物资源已愈来愈引起世人的关注。本文预测了中国和世界木材资源的供需状况，并对如何科学合理地利用木材生物资源进行了分析和论述，为促进高质量高性能的生物材料及衍生制品的创生和发展、保护生态环境和林业的可持续发展提供科学依据。

利用锥形量热仪（CONE）系统地测定了新型木材阻燃剂FRW的阻燃性能，讨论了FRW对阻燃木材在燃烧时的热释放、质量变化及耐点燃性的影响，并与Dricon阻燃剂进行了对比。结果表明，在50kW/m2的热辐射功率下，FRW阻燃处理木材的热释放速率（RHR）和总热释放量（THR）随FRW载药率的升高而降低，至载药率达到10%左右时，RHR及THR降低为未处理木材的50%左右，并且降代的趋势明显变缓；FRW与Dricon阻燃木材的有效燃烧热（EHC）曲线基本重合，说明二者的阻燃机理类似；FRW阻燃木材的质量损失速率（MLR）曲线与RHR曲线相似，失重和热释放主要发生在有焰燃烧阶段；FRW阻燃处理能显著提高木材燃烧时的成炭率，但对木材的点燃时间影响不大；FRW与Dricon的阻燃效力相当，属高效木材阻燃剂。
