摘　　要：近红外光谱技术具有快速、无损、样品易于准备、适合实际生产在线检测等优点,在木材科学研究领域的应用越来越广泛。文中阐述近红外光谱技术在木材纤维素、木质素和抽提物等化学属性预测,生长特性及物理力学特征等物理属性预测,以及在木质复合材料生产中应用的研究进展,分析了其在木材材性分析及木质复合材料生产中的研究趋势。Wood is one of the most important materials and its acoustic vibration properties determine to large extent the acoustical quality of musical instrument. The paper summarized the research progress on the modification of acoustic vibration properties of wood used for soundboard based on the analysis on the start points of the modification. The prospect was also analyzed and the further research hotspots were proposed： 1 ） the research on the modification of acoustic vibration properties of wood from the indexes of modulus of elasticity, specific dynamic elastic modulus, acoustic radiation damping, acoustic impedance, etc. ; 2） the research on functional modifictiaon of alternative wood species to wood used for soundboard for expanding the choice of materials for soundboard making ; 3 ） the research on wood functional modification from the perspective of improving acoustic vibration efficiency and vibration music quality of wood ; 4） the research on new materials for soundboard.
