摘要：

An attempt was made to calculate the experimental heat function from the energy level function of a heterogeneous surface. In order to obtain the heat of adsorption, adsorption was assumed to take place on each energy level. In reversible adsorption, Langmuir's monolayer model was extended to determine the occupation of energy levels by molecules. On this basis, the heat of adsorption could be calculated. Irreversible adsorption was also examined on the basis of chemical kinetics. Molecules were supposed to be held on sites to which they first collided.
