The phrase "a thin ring" is correct and usable in written English.
It can be used to describe a ring that has a small width or thickness, often in contexts related to jewelry, materials, or shapes.
Example: "She wore a delicate, thin ring on her finger that sparkled in the light."
Alternatives: "a slender band" or "a narrow ring".
In this structure a thin ring is placed between the high index core and nonuniform cladding.
The numerical simulations have been performed considering a thin ring, discs and bladed-deformable shafts.
The in-plane stability of a thin ring rotating at relatively high speeds is analysed thoroughly.
It consists of a thin ring that deflects elastically as it rolls on the inside of a slightly larger rigid circular ring.
The free vibration eigensolutions of a thin ring on a general elastic foundation are obtained by perturbation and Galerkin analyses.
This push creates a thin ring of gaseous matter that breaks away from the rest of the system, which in turn contracts a little more until such time as another ring of matter is deposited inward of the first.
But around the central region is a thin, ring-shaped reflective telescope, which expands the perceived size of objects like weak binoculars.
Then the central solar updraft chimney – the power tower – is treated in more detail: a thin ring-stiffened RC shell of extreme height, forming the utmost structural challenge of such plants.
Very recently, a computational model has been developed in Wyczalkowski et al. (2013) considering both circular and elliptical geometries, with experiments, displaying a biphasic behaviour of the wound closure first promoted by the actomyosin isotropic contraction within a thick ring and later by a circumferential contraction within a thinner ring.
The moons Prometheus and Pandora straddle the narrow F ring, a thin band that is kinked and braided by the inner moon's gravity.
The ring, a thin band of gold topped by a tiny diamond, is all that is left after 31 years of marriage.
