前言木材具多孔性,是热的不良导体,可作优良的隔热和保温材料。例如建筑中,用木材作围护材料;冷藏设备方面,作保温隔热材料;日用生活上的炊具柄、锅盖等也离不开木材。木材的热学性质数据是木材加工的重要工艺参数。在其防腐、干燥及胶合板生产的木段蒸煮等各方面均有应用。木材热学性质的主要指标有比热、导热系数和导温系数。测定和研究其热学性质的这三项主要指标,不仅在理论上而且在实践应用中均具重要意义。
Preface Wood is porous, is a poor conductor of heat and can be used as an excellent insulation and insulation material. For example, in buildings, timber is used as enclosure material; in refrigerating equipment, it is used as thermal insulation material; and in daily life, cooking utensils, pots and the like are inseparable from wood. Wood thermal properties of wood processing is an important process parameters. In its anti-corrosion, drying and plywood production of wood cooking and other aspects have applications. Wood thermal properties of the main indicators of specific heat, thermal conductivity and thermal conductivity coefficient. The three main indicators for the determination and study of their thermal properties are of great importance not only in theory but also in practical application.
