In this study the change of brightness, chromatism and infra red spectra of compressed China fir during heat treatment in air or heat treatment in vacuum are studied.

该文重点研究了杉木压缩木材在经过空气介质中热处理和真空中热处理后明度、色差和红外光谱的变化。

The water-saturated and boiled specimens of China fir are hot pressed with the average compression rate of 50%. Then they are heat treated in a common oven or in a vacuum oven, with the temperatures of treatment of 140,160,180,200,220℃, respectively. Then the brightness, chromatism, infra red spectra of the specimens are measured and discussed.
