Principle and Application of Testing Device for Sorption Characteristics under Conditions of Variable Temperature, Variable Pressure and Constant Volume

A testing device for sorption characteristics under conditions of variable temperature, variable pressure and constant volume had been designed on the issues of rapid change of temperature and pressure during the running of thermal battery used for guided weapon. The transition region had met the accuracy requirement after being designed and modified on the basis of the assumption of ideal gases. The absorbing behavior of Li-B based getter could be effectively characterized by the designed testing device under conditions of variable temperature, variable pressure and constant volume.
