Outline of Final Research Achievements	We tried to establish new method involving the wide range multi spectral measurement (X-ray, IR, NIR and THz) of antique wood for understanding of wood degradation. Thermally treated Hinoki, Sugi and Zelkova serrata at 120, 130, 150 and 180 degree was prepared and each spectral measurement were done. Introduction of kinetic analysis to the score calculated by principal component analysis (PCA) of various spectral information allowed us the qualitative and quantitative evaluation of oxidation and hydrolysis. We reported these result to Applied Physics A, 122, 208, 2016)
