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。

以62人（4个组别）观察41个代表性树种的木材样品，对14个视觉心理变量进行评分的心理测验结果为基本数据，探讨了木材视觉心理量变量之间的联系、因子类别划分及其受验者不同组别的视觉心理特点。研究表明：木材视觉心理量的某些变量之间有着内在的联系，可用主成分分析的方法归类，得到综合视觉心理量；不同受验者身份组别的结果具有一些相似性，但某些方面亦表现出不同性别、不同学习经历的受验者的心理特点。

经40%酚醛树脂处理的中密度板样品炭化物简称木陶瓷（WCS），是一种低成本而性能优异的新型多孔炭材料；添加阻燃剂及20%酚醛树脂处理的中密度板样品炭化物简称P_木陶瓷（P_WCS）。本研究采用低温氮吸附法对比木炭研究了木陶瓷的孔隙结构。结果表明，由于样品未经活化，因而吸附能力较差，且以木炭为最差。木陶瓷的微孔面积为314.16m2/g，微孔容积为0.1262mL/g，大于P_WCS，且远远大于木炭。木陶瓷的平均孔径为1.598nm，小于P_木陶瓷，远远小于木炭。说明酚醛树脂为木陶瓷引入了较多的微孔，使其吸附性能远高于传统的木炭。

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.
