The density of green body is increased and the sintering condition is improved after adopting close packing theory. 采用紧密堆积理论对cBN进行级配后,坯体的致密度得到了提高,烧结状况也有明显的改善。
By properly choosing the vibration parameters such as amplitude A and frequency ω, highly dense packing with the packing density of 0.728 can be realized, which is much denser than the maximum packing density of random close packing. 通过适当选择振动参数如振动振幅A和振动频率ω,可以实现堆积密度0.728的高密度堆积,它是比最大随机紧密堆积更致密的堆积。
Experimental control through indoor grille and the interface between the role of the effect of soil, As well as the packing density in different, under different moisture conditions change in the value of packing c 、? 通过室内实验掌握格栅与土间的界面作用效应,以及填料在不同密实度、不同含水率情况下填料的c、?值的变化,找出变化规律,从而得到相关模拟计算参数。
It was also found that higher Reynolds number yielded better shell-side mass transfer. The Sherwood Numbers at high packing density were smaller than those at low packing density. 高Reynolds数有利于接触器壳程的传质,同时,低填充密度时的Sherwood数高于高填充密度时的Sherwood数。
When the density of packing material is smaller than that of liquid, the packing material becomes less dense and expands before flooding. The pressure drop in an expanding packed bed can be calculated by modifying the porosity of the bed. 当填料密度比液体密度小时,在液泛前填料会发生松动和膨胀,通过修正填料床的孔隙度可以计算膨胀填料床的压降。
