They feature increased chromaticity, higher color purity and more brightness and hiding power than traditional non-metallic metallic colors.

它们具有高彩度、高颜色亮度的特点，提供强烈鲜艳的金属颜色效果。

The results are:(1) The brightness of the specimens will decrease and the chromatism will increase with the prolongation of time of heat treatment. Compared to heat treatment in vacuum, the specimens have more color changes after heat treatment in air, with the same temperature and time of heat treatment.

该研究的结论为：(1)在相同条件下，随着处理时间的延长，试材的明度减小，色差增大；空气介质中热处理和真空中热处理相比，在处理温度和时间相同的情况下，前一种方法处理后的试材材色较深。

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。

As far as the relationships between brightness, chromatism and recovery are concerned, there is little difference between heat treatment in air and heat treatment in vacuum. The fixation degree of compression set is closely related to the change degree of color.

2就热处理过程中杉木试材的明度、色差与回复率之间的关系而言，两种热处理方式之间的差异不大；热处理中木材变定的固定程度与木材颜色的变化程度有关。

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.

为了探讨热处理过程中杉木压缩木材的材色变化规律，以及材色和木材化学主成分变化之间的关系，该研究测定了空气介质和真空中热处理杉木压缩木材(热处理温度范围140～220℃，时间范围0～36h)的明度、色差以及红外光谱。
