N2 - On the basis of physical process analysis of molecular contamination deposition under ultraviolet irradiation, the model of contamination quantity from organic material is proposed. Then ground experiment is performed on the molecular contamination deposition process irradiated by the ultraviolet using silicon rubber material, and the influence of ultraviolet irradiation on the contamination deposition of spacecraft is studied. It is shown from experimental results that the UV irradiation has a significant enhancement on the deposition of contamination, and this effect increases linearly with the radiation dose, but decreases with the deposition temperature.
