    摘要： The subject of the invention is a structure for filtering particle-laden gases, of the honeycomb type and comprising a set of longitudinal adjacent channels of mutually parallel axes (21, 22) separated by porous filtering walls (23), the said channels (21, 22) being alternately plugged at one or other of the ends of the structure so as to define inlet channels (21) and outlet channels (22) for the gas that is to be filtered, and in such a way as to force the said gas to pass through the porous walls (23) that separate the inlet (21) and outlet (22) channels, the said structure being such that in cross section: - the ratio R between the sum of the areas of the inlet channels and the sum of the areas of the outlet channels is greater than 1, - at least some of the porous walls (23) have undulations such that they are concave with respect to the centre of the inlet channels (21) and convex at their middle with respect to the centre of the outlet channels (22), - the outlet channels (22) have at least one rounded corner (25).

    摘要： The invention relates to a structure for filtering gases charged with particles, of the honeycomb type and including an assembly of longitudinal adjacent channels with parallel axes and separated by porous filtration walls, in which: each outlet channel has a wall that is common with six inlet channels, each common wall defining a side of said outlet channel, each outlet channel including six sides having a substantially identical width a in order to define a channel having a substantially hexagonal and regular section; at least two adjacent sides of each inlet channel have a different width; and at least two inlet channels sharing a wall with a same outlet channel, share a common wall having a width b, wherein the ratio between the widths b/a is equal to 1.
