释义 | corrugation noun uk /ˌkɒr.əˈɡeɪ.ʃən/ us /ˌkɔːr.əˈɡeɪ.ʃən/ [ C ] a line or fold on the surface of something: The path is full of corrugations which make it unsuitable for caravans. On this scan, you can see the normal corrugations of the brain surface. [ U ] the fact of having small lines or folds on a surface: I moved a finger across the surface but could not detect any corrugation. The manufacturers use corrugation to keep the bottles strong despite the thinness of the glass. The surface of the planet has many sharp corrugations. The whole van shook as we went over the potholes and corrugations. To get to the farm we had to go down a track with many ruts and corrugations. The track had a series of corrugations running across it at right angles. Patterns and shapes amorphous arabesque argyle asymmetrically asymmetry flecked formless formlessly fretted geoglyph scalloped scissor semilunaris shapeable shaped wavery wavily weave willow pattern zigzag Related wordcorrugated Examples of corrugationcorrugation The corrugation used was moderately nonuniform in depth. Rutkevich et al. (1996) found that the spontaneous emission of sound waves from strong shocks in metals results in corrugation of a planar shock front. Hence, the effect of the surface corrugation is to decrease the surface temperature gradient and hence the surface-tension gradient compared to the flatinterface case. Sections cut further along the protruding plate, gave rise to a biconvex profile with corrugations on both sides, due to the emerging form of the spine teeth (fig. 5). Its main rôle in the first instance is to help iron out the corrugations and clear the blockages in the system. From the Hansard archive Example from the Hansard archive.

Since the turbulence inside the rotating tube is complex and still not well understood, we modelled the effect of corrugations. If the electron beam is away from corrugation wall, the temporal growth rates decrease. Corrugation and invaginations of the surface are also less extensive than on the ventral side of the body. Consider the case of a sinusoidal corrugation carved from a solid with the surface pattern repeated in depth. The corrugations of such tubes must be located inside the tube, otherwise the tube does not sing. Symmetrically positioned corrugations produce the most desirable sonorities. The temporal growth rate becomes the maximum in the vicinity of the inner corrugation wall for both cases. By varying the slow-wave structure corrugation period, the frequency could be tuned within a 10% band. The effect of the small-scale corrugations is that to avoid the formation of a single magnetic channel. These examples are from corpora and from sources on the web.
