Aluminium oxide primarily used for the production of aluminium . determination of specific surface area by nitrogen adsorption . single - point method 鋁生產(chǎn)用伯氧化鋁.用吸氮法測(cè)定比表面積.單點(diǎn)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 大量室內(nèi)實(shí)測(cè)數(shù)據(jù)驗(yàn)證結(jié)果表明單點(diǎn)法和多點(diǎn)法都可以應(yīng)用于計(jì)算質(zhì)量吸收系數(shù)的值,且具有較高的計(jì)算精度。
