Question

propagation n.(动植物)繁殖；(声波,电磁辐射等)传播 Propagation has two main uses, both having to do with multiplying something. If it's used in relation to creatures, that means that the creatures are multiplying — having kids. A synonym for this is procreation. We also propagate ideas. Use propagation for anything that multiplies and spreads through larger and larger numbers or spaces — from the propagation of weeds in your garden to the propagation of belief in the divinity of snowmen. In physics, propagation is wave movement. 2010.3

Accepted Answer

[prɔpə'geiʃ(ə)n] If your dog is about to have puppies, then she's is engaged in the propagation of dogs, the creation of new life to further the species. Our work shows that the principal requirement for what we call "global cascades"– the widespread propagation of influence through networks – is the presence not of a few influentials but, rather, of a critical mass of easily influenced people, each of whom adopts, say, a look or a brand after being exposed to a single adopting neighbor.
