- Die Porenziffer, auch Porenzahl oder selten relativer Porenraum genannt, ist eine Kenngröße zur Charakterisierung eines porösen Stoffes. Sie ist ein Maß dafür, wie viel Raum der eigentliche Feststoff aufgrund seiner Körnung oder Klüftung innerhalb eines bestimmten Volumens ausfüllt bzw. welche Hohlräume er in diesem hinterlässt. Die Poren sind dabei in der Regel mit Luft und/oder Wasser gefüllt. (de)
- The void ratio of a mixture is the ratio of the volume of voids to volume of solids. It is a dimensionless quantity in materials science, and is closely related to porosity as follows: and where is void ratio, is porosity, VV is the volume of void-space (such as fluids), VS is the volume of solids, and VT is the total or bulk volume. This figure is relevant in composites, in mining (particular with regard to the properties of tailings), and in soil science. In geotechnical engineering, it is considered one of the state variables of soils and represented by the symbol e. Note that in geotechnical engineering, the symbol usually represents the angle of shearing resistance, a shear strength (soil) parameter. Because of this, the equation is usually rewritten using for porosity: and where is void ratio, is porosity, VV is the volume of void-space (air and water), VS is the volume of solids, and VT is the total or bulk volume.

- 간극비(공극비, void ratio)는 혼합물에서 고체의 부피에 대한 고체를 제외한 (또는 공극)의 부피의 비를 일컫는다. 이를테면, 토질역학에서 간극비는 흙 입자의 부피에 대한 간극 즉, 물과 공기의 부피의 비로 정의된다. 즉, 여기서 는 간극의 부피, 는 고체 성분의 부피이다. 공극률(간극률, porosity)과는 다르다. (ko)
- Коэффициент пустотности (согласно ГОСТ 25100-2020 Коэффициент пористости ) — отношение объёма пустот к объёму твёрдых частиц . Стоит заметить, что в объём пустот входит объём воды и объём воздуха (пористость). (ru)
