Aluminium oxide primarily used for the production of aluminium . determination of specific surface area by nitrogen adsorption . single - point method 铝生产用伯氧化铝.用吸氮法测定比表面积.单点法
Much experiment data indicates that the single - point method and multi - point can both applied to estimate its value and their precision is very high 大量室内实测数据验证结果表明单点法和多点法都可以应用于计算质量吸收系数的值,且具有较高的计算精度。
