释义 | permeation noun[ U ] formaluk /ˌpɜː.miˈeɪ.ʃən/ us /ˌpɝː.miˈeɪ.ʃən/ the act of spreading through something and becoming present in every part of it: The lake loses much of its water through permeation into the underlying sand. The next chapter of the book will discuss the permeation of rock music into wider society. The meat had not been marinated for long enough to allow a really deep permeation of the spices. Many commentators have drawn attention to the internet's permeation of every aspect of modern life. They adopted a policy of infiltrating radical groups by steady permeation. Filling and completing backfill box ticking brick brick something up brim fill jam occupy overcrowd overrun pack something/somewhere out permeate plug squeeze (someone/something) in/squeeze (someone/something) into something stuffing suffuse supersaturated take something up tank tie Related wordpermeate Examples of permeationpermeation In addition, the underlying heat permeation makes it difficult to control final dimensions. Each connexin had a characteristic ' fingerprint ' of relative permeabilities to the tracers, establishing clear distinctions among the permeation pathways. This general formulation enables incorporation of arbitrary factors that influence ion permeation as long as they can be expressed as a chemical potential. What is clear is that any treatment of the energetics of permeation (and selectivity) will be sensitive to the choice of parameters. That ion channels are flexible, and that their motion may be coupled to permeation remains a difficult problem. That is, the electrical conductance of the pore is reduced by anion permeation. Atomic structure of a glycerol channel and implications for substrate permeation in aqua(glycero)porins. The increases in both lactulose and mannitol recoveries in the present study indicate that both transcellular and paracellular permeation routes are affected. Nonetheless, it had a very wide circulation and had a profound impact on computational studies of ion permeation. In addition to permeation, the other aspect of channel function we would like to explain is ion selectivity. Using theory and simulation to understand permeation and selectivity in ion channels. A rapid healing of the membrane follows this transient permeation. Thus, simply averaging across atomistic simulations is not going to provide a picture of ion permeation. Brownian dynamics study of a multiply-occupied cation channel - application to understanding permeation in potassium channels. Gains in computational efficiency is not, however, the only motivation for adopting this perspective on ion permeation. These examples are from corpora and from sources on the web.
