摘　　要：实验研究了1．0×1011-1．0×1017 p／cm2通量范围内110keV质子辐照引起的温控涂层热光性能的变化．实验表明,在1．0×1011p／cm2通量辐照下6种温控涂层材料的相对光反射率基本没有变化,当辐射通量在1．0×1012-1．0×1016p／cm2范围变化时,某些低吸收率的温控涂层的太阳吸收率随着辐射通量增加先变小而后又增大．这一特性对于制备更低太阳吸收率的温控涂层具有应用价值．It is investigated experimentally how the thermal properties of some specimens of thermal control coatings change with irradiation fluence ranging from 1.0×10^11 p/cm^2 to 1.0×10^17 p/cm^2 with 110keV proton beam. It is shown the thermal properties of all the 6 specimens examined nearly do not change at exposure of 1.0×10^11 p/cm^2. The solar absorptance of some specimens of thermal control coating of low absorptance increases at first and decreases whereafter as the proton fluence rises from 1.0×10^12 p/cm^2 to 1.0×10 ^16 p/cm^2. This indicates that the irradiation method may be used to promote the thermal properties of some thermal control coatings of low solar absorptance.
