摘　　要：氙弧灯、紫外荧光灯、碳弧灯是3种常见的高分子材料人工加速光老化方法,主要介绍了3种光源的特点及人工加速光老化测试后的评价方法。氙弧灯所发射的光谱经滤镜过滤后可模拟最接近日光的紫外波段;紫外荧光灯老化强度最大,能最快得出实验结果;碳弧灯的光谱和日光没有多大吻合性,强度介于两者之间。Xenon arc light,fluorescent UV light,carbon arc light are the common artificial light sources for polymer material accelerating aging.Each of the characteristic was explained,as well as the assessment after aging.The xenon arc light,with properly filtered,simulates UV and visible solar radiation more closely than any other artificial light source.Fluorescent UV light is the maximum strength in the artificial light source.The spectral emission in the carbon arc light bears little resemblance to sunlight,and its strength is between the xenon arc light and fluorescent UV light.
