摘　　要：用柚木刨切、砂光后的试样,通过氙光灯照射,对试样进行曝晒,确定光照后试样明度L、红绿轴色品指数a、黄蓝轴色品指数b以及色差E在光照后的变化规律。Sliced teak （Tectona grandis） veneer was irradiated by xenon lamp after sanding and then was under the blazing sun for quite a long time, the dis coloration rules were found after xenon lamp irradiation, the rules were that of the lightness （L）, the chromaticity indexes at red to green axis （a）, the chromaticity indexes at yellow to blue axis （b） and color difference （ △ E）.
