A procedure is developed for physical and chemical modeling and investigation of the weight, geometrical, and thermo-optical characteristics of polymer paneling materials of solar arrays and of the electric power of solar cells under the prolonged action of supersonic fluxes of atomic oxygen in orbit. The behavior of changes in the material characteristics as a function of the integral fluence of atomic oxygen is found. It is established that the electric power of solar cells is virtually invariable within the errors of measurements under irradiation by atomic oxygen flux with a fluence of no higher than 5 · 1021 cm?2. 相似文献

A comparative analysis of variations of the mean solar magnetic field and the interplanetary magnetic field over all history of their measurements is performed. Asymmetry of the solar magnetic field and its manifestation in the heliosphere is investigated. Long-term variations of the solar magnetic field and the heliosphere, which manifest themselves in alternation of dominating magnetic polarities of different sign, are discovered. On the basis of the analysis of cumulative sums of the IMF components, long-term variations of the IMF geometry and of the solar wind spiral angle are found. The cumulative sum of the IMF B z component perpendicular to the ecliptic plane also shows long-term variations. Time intervals are revealed, in which negative values of the IMF B z component dominate, and an increased geomagnetic activity is observed. 相似文献
