BET装置的用途很广,我们用它来测定催化剂比表面。原设备体积庞大,结构复杂,操作麻烦,且内装大量水银,严重危害操作人员的身体健康。无产阶级文化大革命以来,此装置经改进,由原来占地面积9平方米,缩小到占地面积不到2平方米,增加了4个吸附柱,效率提高了3倍。1974年我们又将装有近30公斤水银的麦氏真空计改为复 The use of the BET device is very extensive and we use it to determine the specific surface area of ​​the catalyst. The original equipment is bulky, complex structure, troublesome operation, and contains a large amount of mercury, seriously endangering the health of operators. Since the Great Proletarian Cultural Revolution, this device has been improved, from an original 9 square meters land area to an area of ​​less than 2 square meters, an increase of 4 adsorption column, the efficiency increased by 3 times. In 1974 we again replaced the Mecklenbach Gauge with nearly 30 kg of mercury
