摘　　要：太阳辐射是引起有机材料老化的最主要原因。由于拉萨高原地区的太阳辐射年总量比内地同纬度高出约1倍,在拉萨进行有机涂层样品的户外暴露试验,其老化速度可大大提高。通过在拉萨试验站对4种常用的有机防护涂层开展太阳跟踪反射聚光户外加速试验和自然暴露试验对比研究,优选出了环境适应性好的材料,并验证了其加速性。The solar radiation was the most important factor of organic material weathering. Because the level of the solar radiation in Lhasa of tableland was twice higher than in backland of the same latitude, the weathering rate of organic coating was consumedly elevated for the samples tested in Lhasa. The accelerated outdoor weathering test and natural exposure test of four types of common protective coating was carried out in Lhasa. The relative durability of the materials was determined and the acceleration rate of the method was validated.
