孔径分布（pore size distribution）是指材料中存在的各级孔径按数量或体积计算的百分率。一般测试样品的孔径分布，所使用的方法就是静态容量法和压汞法。其原理是通过测试的分压和对应 …

Pore size refers to the size of the openings or gaps in a filter membrane, which can vary depending on the method used to determine the porosity. It is important to note that pore size …

Pore structure is a common term employed to characterize the porosity, pore size, pore size distribution, and pore morphology (such as pore shape, surface roughness, and tortuosity of …

Mercury intrusion capillary pressure (MICP) measurements are the standard method for characterizing pore features, particularly pore throat size distributions in porous media from …

A soil’s porosity and pore size distribution characterize its pore space, that portion of the soil’s volume that is not occupied by or iso-lated by solid material. The basic character of the pore …

2019年9月1日 · In this study, we clarify the relationship between pore diameter (d) and pore width (w), two terms interchangeably used in the literature. The former corresponds to a cylindrical …

When considering pore size, a set of standards approved by IUPAC has defined pore size ranges based on different size widths. Pores with an internal width of less than 2 nm are referred to as …

The characteristics of membrane pore structures (pore size, pore size distribution, pore density, surface roughness, etc.) should be the backbone of the membrane industry, since such …

Gas-liquid porometry is also known as Capillary Flow Porometry (CFP), measures pore size and pore size distribution of through pores in materials. The technique is based on the …

2017年8月17日 · We determined critical pore size by measuring the pressure at which gas passes through a porous medium; The critical pore size controls permeability over more than 10 …
