hole de ity
hole density
Examples
- Hole density : the number of holes per unit area on a pcb
孔密度： pcb上单位面积上的孔数。 - The cells in barrier anodized aluminum films are arranged in hexagonal arrays at aluminum / alumina interface . furthermore , the effect of anodizing voltage on cell sizes , pore diameter , pore density and cell density are studied
阻挡层氧化铝膜中的晶胞大小一致，且在铝氧化铝界面上排成六方形阵列；另外，研究了阳极氧化电压对晶胞尺寸、孔径大小、孔密度和晶胞密度的影响。 - Results indicate that in the given range cells sizes and pores diameters in porous anodized aluminum films increase with the increase of anodizing voltage , while pores densities and cells densities decrease with the of increase anodizing voltage
结果表明在一定的电压范围内多孔氧化铝膜的孔间距，孔径、晶胞尺寸均随阳极氧化电压的增加而增加，孔密度和晶胞密度却随阳极氧化电压的升高而减小。 - At last , the impact of the monolith length , cell density , wall thickness and noble metal dosage on the light - off characteristic and conversion efficiency of three - way catalytic converter are analyzed and could provide a guide for the optimization of three - way catalytic converter
本文还对载体长度、孔密度、孔道壁厚和催化剂用量对催化转化器起燃特性和转化效率的影响进行了分析,为载体参数的优化设计提供了依据。 - The relationship between capacitance and corrosion conditions in the enlargement of tunnels justifies the latter competition mechanism the varied etching conditions were implemented by enhancing the passivating characteristics and viscosity , changing the a13 + concentration , temperature of etchants and current pulsation . passivating acid in the etchant is conducive to the instant passivation of exposed areas on the foil surface , and hence sustains the balance of competition between aggressive anions and passivators , providing pit nucleatiori sites continuously
通过侵蚀液中添加草酸、硫酸、乙二醇，改变侵蚀液al ~ ( 3 + )浓度和电流纹波等方法，研究了不同的侵蚀条件对隧道孔形貌和比容的影响，结果表明：草酸和硫酸既保护了铝箔表面又促进了隧道孔孔壁的迅速钝化，增加发孔密度。
