| 书目名称 | Powder Surface Area and Porosity | | 编辑 | S. Lowell,Joan E. Shields | | 视频video | | | 图书封面 |  | | 描述 | The rapid growth of interest in powders and their surface properties in many diverse industries prompted the writing of this book for those who have the need to make meaningful measurements without the benefit of years of experience. It is intended as an introduction to some of the elementary theory and experimental methods used to study the surface area, porosity and density of powders. It may be found useful by those with little or no training in solid surfaces who have the need to quickly learn the rudiments of surface area, density and pore-size measurements. Syosset, New York S.
