摘　　要：本文采用热脱附(TDS)的实验方法,以多孔性Porapak微球为样品,测定了氧气、乙醇分子在Porapak Q、N两种样品上的脱附级数n和脱附活化能Ed,并与气相色谱法测定的吸附热作了比较。得出Ed≥ΔH令人满意的结果。In this paper, the clcsorplion activation energies and reaction orders were studied for O_(2) and C_(3)H_(5)OH adsorbed on Porapaks by means of TDS. The results obtained were coincident with the heais of adsorption from. GC measurement according to the relation En- Ea - ΔH.
