本文论述了深冷霜的吸附机理,测定了77K下CO_2霜对干空气的吸附平衡等温线,获得国内外尚未报道的结果。本文的结果对低温物理的基础研究以及宇宙模拟,低温真空绝热技术等应用领域具有一定的指导意义。
In this paper, the adsorption mechanism of cryo-cream was discussed. The equilibrium isotherm of adsorption of CO_2 at 77K on dry air was obtained, which has not been reported at home and abroad. The results of this paper are of guiding significance for the basic research of cryogenic physics and the applications in space simulation and cryogenic vacuum insulation.
