空间紫外辐射环境可造成航天器材料的光学性能、电学性能或力学性能退化甚至失效。在地面模拟试验过程中较难真实模拟空间紫外辐射环境，因此，通常采用基于效应等效原理的加速模拟试验方法。文章首先对国内外紫外辐射效应试验方法和标准现状进行梳理，进而从紫外曝辐量的计算方法、紫外波长的选择、模拟光源选用、温度选择与控制以及总曝辐量和加速因子的选择等角度对紫外辐射效应地面模拟试验方法进行分析研究，并给出应进一步开展工作的建议。

Space ultraviolet irradiation may cause degradation of optical, electrical or mechanical properties of spacecraft materials. With ground simulation tests, it is difficult to simulate completely the space violet environment. So the accelerated testing method is usually used based on the effect equivalence. But many problems would arise, such as how to select suitable testing parameters, which should be carefully studied. The testing method and the standard for the ultraviolet irradiation test are first discussed, and then the calculation method of the ultraviolet radiant exposure, the choice of the simulation sources and the wavelength, the temperature, the acceleration factor, and the total radiant exposure are analyzed. At last, some further study topics are proposed.
