In this article the authors consider methods of determination of total absorbing ability of high-vacuum cylindrical cryoadsorption pumps: average temperature calculation and integrated calculation. These two methods were compared with each other. The authors also considered an algorithm of calculation of a relative error of the method of determination of total absorbing ability by using an average temperature. Influence of various parameters, such as temperature on the periphery of the adsorptive layer, the radius of a cryogenic vessel, etc., on the mistake value was revealed. Results of calculation were presented in graphic and analytical interpretations. On the basis of the conducted researches several conclusions were drawn.
