(EN) Honeycomb structure
(ZH) 蜂窝状结构体
要約
(EN)
This honeycomb structure (1) has dividing walls (11) and a plurality of cells (12). In a cross-section perpendicular to the axial direction of said honeycomb structure (1), the honeycomb structure (1) has a plurality of cell-density regions (2), with different cell densities, in the radial direction from the center of the honeycomb structure (1) to the outside thereof. A border region (14) is provided between adjacent cell-density regions (2), separating said regions (2). Said border region (14) has the following: border dividing walls (141) that connect the dividing walls (11) of the cell-density regions (2) on either side; and a plurality of polygonal border cells (142) that are each surrounded at least in part by border dividing walls (141) and are shaped differently from the cells (12) in the cell-density regions (2) on either side. The mean hydraulic diameter ([Phi]1) of the border cells (142) in the border region (14) and the mean hydraulic diameter ([Phi]2) of the cells (12) in the cell-density region (2) immediately inwards of the border region (14) satisfy the relation [Phi]1/[Phi]2 >= 1.25.

(ZH)
该蜂窝状结构体(1)具有隔壁(11)和多个单元(12)。在蜂窝状结构体(1)的垂直于轴向的横截面中,蜂窝状结构体(1)具有沿径向从蜂窝状结构(1)的中心到其外侧具有不同单元密度的多个单元密度区域(2)。边界区域(14)被设置在相邻的单元密度区域(2)之间,分离所述区域(2)。所述边界区域(14)具有以下部分:在两侧连接单元密度区域(2)的隔壁(11)的边界隔壁(141);和多个多边形边界单元(142),多边形边界单元中的每个至少部分地由边界隔壁(141)包围并且被形成为具有不同于在两侧的单元密度区域(2)内的单元(12)的形状。在边界区域(14)内的边界单元(142)的平均液压直径(Φ1)和在边界区域(14)的紧接内侧的单元密度区域(2)内的单元(12)的平均液压直径(Φ2)满足Φ1/Φ2>=1.25的关系。
