比表面面积的英文

例句与用法

1. Determination of specific surface area of solids by adsorption of nitrogen ; single - point diffenrential method according to haul and duembgen
   用氮的吸收法测定固体比表面面积. haul及duembgen的单
2. The interface behavior between essence and ethylene - vinyl acetate copolymer pallets was studied so that necessary data were obtained to guide the preparation of fragrant masterbatch . the adsorption type and wettability between essence and the copolymer pallets were analysed by measurements of fourier transform infrared spectrum , surface tension , contact angle and specific surface area . the technical factors affecting absorptivity such as the charge ratio , temperature , pressure and stirring speed were studied by series of adsorption experiments . the results showed that the adsorption of essence on the surface of ethylene - vinyl acetate copolymer pallets is physical in nature . essence couldn ' t moisten the surface of ethylene - vinyl acetate copolymer pallets absolutely , but it could be soaked into the surface of the pallets partly . adsorptivity could be increased by enhancing the temperature , pressure and stirring speed , but the extension of adsorption time had little influence on adsorptivity
   研究了香精与乙烯/醋酸乙烯共聚物粒子之间的界面行为，以便为香型母粒的制备提供必要的理论依据.利用傅立叶变换红外光谱、表面张力、接触角及比表面面积等测定手段，分析了香精与载体之间的吸附类型和润湿作用.并通过一系列吸附实验，讨论了配料比、温度、压力、搅拌等工艺条件对吸附量的影响.结果表明，香精在乙烯/醋酸乙烯共聚物粒子表面的吸附为物理吸附；香精无法完全润湿载体粒子表面，但可以对其形成部分浸润；提高温度、压力、搅拌速度可以增加吸附量，而延长吸附时间对增加吸附量贡献不大
