Based on the criterion of avoiding the loss of the effective spatial-frequency information,the restrictive conditions of the spatial arrangement are calculated,and then the effective frequency coverage range and the equivalent aperture are obtained.
根据避免有效频率信息丢失的原则,分别计算了三种结构各自对应的空间排布限制条件,在此基础上得到了三种结构的有效频率覆盖范围和等效孔径。
The relationship among the valid porosity,permeability coefficient,plane porosity,equivalent aperture and compressive strength and the situation of pore distribution is also discussed.
分别研究了单掺粉煤灰、矿渣和硅灰3种矿物掺合料的多孔混凝土有效孔隙率与目标孔隙率之间的关系,并探讨了掺有矿物掺合料时多孔混凝土有效孔隙率、透水系数、平面孔隙率、等效孔径和抗压强度之间的关系以及等效孔径大小的分布情况。
Through the case study we analyze the definitions,measurements and sizes of the equivalent aperture in different specifications home and abroad.
