ตัวอย่าง concentric

• A purely elastic instability apparently also occurs by a similar mechanism in other rotational shearing flows, namely concentric plate-and-plate flow and concentric cone-and-plate flow.

• The internal and external elastic laminae are thick concentric elastic-fibre layers that separate the intima and media, and the media and adventitia, respectively.

• Concentric-whorled membranes, having a granular appearance resembling the ribosomes of rough endoplasmic reticulum, float in the pseudocoelom between somatic muscles, reproductive tract and intestine.

• The concentric spherical shells, the so called "onions," constitute a form of carbon consisting of spherical concentric layers of carbon shells.

• Euhedral concentric zoning is common in most crystals.

• Again the isobars are concentric cylinders about the origin 0 and correspond with a pressure maximum.

• The inner crater in the crystalline basement is often the only part of the concentric structure that is preserved or recognizable.

• The excretory pore is located at the posterior extremity of the worm with the tegument forming tight concentric bands around the pore.

• The orientation boundary is made up of two offset concentric circles.

• In any case, all schemata representing concentric circles are misleading (as in discussions of identity).

• In the convoy, important relationships are identified and situated in three concentric circles around the self, arranged according to importance and closeness.

• They were asked to arrange their attributes in one of three concentric circles (center, intermediate, and outer) corresponding to importance of each attribute.

• One checks easily that this is the only other possibility for a cycle of circles of period 3 that is concentric about the origin.

• At the centre of the chamber base, a typical, rather small basal scar can be observed on all specimens, consisting of two concentric circles.

• There are indications that it is similar to the mechanism shown to cause orientation bias in cat concentric cells.
