The change in the diffusion reflection spectra and the total solar radiation absorption coefficient as by a reflecting heat-regulating coating (HRC) fabricated from ZnO pigment and K2SiO3 liquid potash glass in the People's Republic of China is investigated as a function of the flux density , the flux , and the energy E of electrons. The established regularities in the changes of a
s and under irradiation provide additional information on the formation of color centers (CC) in these systems and correlate with the results obtained previously for coatings fabricated in Russia. 相似文献

本文研究了砷(Ⅲ)在硫酸-盐酸-溴化钾-硒(Ⅳ)体系中的极谱行为。砷(Ⅲ)在-0.53V(vs.SCE)出现灵敏的导数极谱波,检测下限达0.001μg/ml。硒(Ⅵ)的存在是获得高灵敏度砷(Ⅲ)波的关键。研究表明,该波具有吸附性质。本文还探讨了巯基棉富集分离矿石溶液中微量砷的条件,在硫酸介质中,用一次加入巯基棉的方法,有效地从有大量基体元素的矿石溶液中富集分离砷。本文经实际应用,效果很好。 相似文献

The results of ground-based tests of coatings under separate irradiation by electrons and protons with energies of several tens of kiloelectronvolts and under simultaneous irradiation by electromagnetic radiation with spectrum close to the solar one and by electrons, which imitate field conditions, are presented. Changes in the total solar radiation absorption coefficient have been predicted for a 30-year period of operation of the reflecting heat-regulating coating prepared from F4MB-grade fluoroplastic with deposited aluminum and placed in a geostationary orbit. The prediction is made under a special program which allows an optimal solution to be chosen from a set. 相似文献
