瓦斯吸附常数测定中罐体积标定新方法

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

为了解决原抽真空标定罐体积方法中,当泵的真空度达不到要求时所标定的罐体积比真实值偏小,从而造成瓦斯吸附常数测值误差的问题,通过实验验证得到2种瓦斯吸附常数测定过程中对罐体积标定的新方法,即高压充气法和加水充气法。

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 experi-ments are done to obtain two new methods for the calibration of the tank volume, which is used to calculate the gas adsorption con- stants, namely high-pressure inflation and watering inflation.
