New Method for the Calibration of the Tank Volume in Measuring the Gas Adsorption Constants

In order to solve the problem that the measured value of the tank volume is smaller than the true when the vacuum degree of pump for vacuum calibration is lower than the requirement,it results in the calculation error of the adsorption constants. The experiments are done to obtain two new methods for the calibration of the tank volume, which is used to calculate the gas adsorption constants, namely high-pressure inflation and watering inflation.
