    摘要:

    孔径及其分布显著影响着多孔体的透过性、渗透速率、过滤性等一系列性能。本文介绍多孔材料孔径及其分布的常用测定方法,包括断面直接观测法、气泡法、透过法、压汞法、气体吸附法、液.液法、悬浮液过滤法、X射线小角度散射法等,并对几种测量方法进行了比较。

    Abstract:

    The aperture and its distribution plays a remarkable role in permeation behavior, infiltration rate and filtration character of porous bodies. The methods in common use for determining the aperture and its distribution of porous materials are introduced, which include the direct observation from cross-section, the gas-bubble method, the permeation method, the mercury method, the gas-adsorption method, the liquid-liquid method, the suspension-filtration method, the X-ray small-angle scattering method, and so forth; and several measuring methods are compared with one another.
