Definition of toroid in English:



  • 1Geometry
    A figure with a shape resembling a torus.

    ‘As an example of the benefits of toroids, consider a concave spherical mirror used to image an off-axis point.’
    • ‘A remarkable feature of oligoamine-condensed DNA is the ability to assume condition-defined morphologies such as spheroids, toroids, and rods.’
    • ‘Polyelectrolytes having complete charge neutralization, like uncharged polymers in poor solvents, can collapse to toroids, rods, or spherical globules.’
    • ‘When stretched at fixed displacement, the toroid undergoes a transition from an ellipse to a tadpole regime.’
    • ‘It is an asymmetrical oval slice of toroid, tilted out of the ground towards the south to catch the sun's heat.’
    • ‘DNA molecules shorter then the persistence length do not form structures like toroids, but their condensed phase is still ordered and has liquid-crystalline properties.’
    • ‘Although there is still some controversy surrounding the exact reason for the formation of toroids, there is one fairly simple model that accounts for most of the properties of toroids and gives a simple prediction for their size.’
    • ‘The roof structures, supported by laminated wood beams and a mill deck structure, are generated by complementary toroids (which can be understood as the surface of a doughnut).’
    • ‘Yet another explanation is that DHPC diffuses along a continuous path consisting of the edges of bicelle disks or toroids in close edge-to-edge contact.’
    • ‘Electron microscopic analysis also indicated that the DNA was in a ring-like structure, probably toroids.’
    • ‘Under some conditions, DNA toroids or rods are not uniformly smooth, but show globular substructure.’
    • ‘In the previous section, a simple argument was presented to determine when toroids formed in bulk solution.’
    • ‘Calculations showed that the flux features were nicely reproduced, provided the toroid was observed edge-on - but the polarization was much too strong.’
    • ‘Each one, curved in two directions, is a slice off the same part of a toroid, with the seven slices tilted around their long axes and arranged in a series of loosely overlapping shells.’
    • ‘The roof shapes are engaging, seemingly free-form, but are actually segments of a toroid (essentially, a donut).’
    • ‘The geometry of the house is based on that of an elliptical toroid.’
    • ‘The structural role of the toroid was assumed to be a pier to which two bracelets are fixed by 12 connections.’
    • ‘The toroid adds additional optical power in the vertical direction to bring the two focal planes together.’
    • ‘As far as I'm concerned, it's glazed toroids from here on out.’
    • ‘The five forms curve with or away from each other - both vertically and along their lengths in a flattened-S toroid form - to create a series of spooning or ovoid spaces.’
    1. 1.1Electronics A coil shaped like a torus or doughnut.
      ‘There are two forms of toroids: one is part of a ring and the other is barrel-shaped; the power of such surfaces can be positive or negative.’
      • ‘The observed condensates are typically found to be toroids with an average diameter ranging from 25 to 300 nm, and occasionally as rods with average length ranging from 40 to 80 nm.’
