电介质球聚集体的力学平衡
Mechanical equilibrium of aggregates of dielectric spheres
摘要:
工业以及自然聚集的细颗粒被认为是与静电。然而,同性电荷相斥,因此不清楚类似处理的粒子如何聚集。为了解决这一明显的矛盾,我们分析了必要的条件举行聚集在一起的静电力。我们发现,由于电介质的极化,带相同符号电荷的粒子聚集在一起,我们评估聚集体尺寸的影响,我们简要总结了实际聚集的后果。
英文摘要:
Industrial as well as natural aggregation of fine particles is believed to be associated with electrostatics. Yet like charges repel, so it is unclear how similarly treated particles aggregate. To resolve this apparent contradiction, we analyze conditions necessary to hold aggregates together with electrostatic forces. We find that aggregates of particles charged with the same sign can be held together due to dielectric polarization, we evaluate the effect of aggregate size, and we briefly summarize consequences for practical aggregation.
