It is of importance to investigate the degradation mechanism of antique wooden materials used for historical temples, buildings and crafts from the viewpoint of both wood science and archeology. In this paper, we applied FT-NIR spectroscopy to monitor the degradation process antique wood, that have been buried in Kiso Mountain for more than 1000 years. The physical, chemical and mechanical properties of the antique hinoki cypresses weresystematically measured. Compressive Young’s modulus of oven tried wood divided by oven-dried density, break strength, equilibrium moisture content significantly decreased as a function of ageing time, whereas crytstallinity increased.Partial least square (PLS) regression analysis was employed to predict these properties The prediction gave strong relationships between measured and predicted value for ageing time

从木材学和考古学的角度探讨古庙、古建筑、古工艺等木质材料的降解机理具有重要意义。在本文中，我们应用傅立叶变换近红外光谱监测老化过程中的古董木材，已被埋在木曾山超过1000年。本文系统地测定了仿古扁柏的物理、化学和力学性能。随着老化时间的延长，木材的压缩杨氏模量、抗折强度、平衡含水率均显著降低，而结晶度则显著增加，采用偏最小二乘法（PLS）回归分析对这些性质进行了预测，预测值与老化时间的预测值之间有很好的相关性。
