释义

Definition of viscosity in English:

viscosity

nounPlural viscosities vɪˈskɒsɪtiˌvɪˈskɑsədi
mass noun
  • 1The state of being thick, sticky, and semi-fluid in consistency, due to internal friction.

    黏稠,黏性

    cooling the fluid raises its viscosity
    Example sentencesExamples
    • By the way, rheological properties mean viscosity and its effects.
    • As a result, density and viscosity both decrease, and the magma becomes buoyant and mobile.
    • The pore lifetime has been interpreted as interplay between the pore edge tension and the membrane viscosity.
    • When liquid helium is cooled to within a couple of degrees of absolute zero, it flows without any friction or viscosity.
    • Their lower viscosity and greater lateral mobility explain why the mafic magmas were distributed over a much wider area than the felsic magmas.
    • He and Gross also want to find other genes involved in fruit softening in hopes of further improving firmness or viscosity.
    • The experiment began in 1927 and demonstrates the high viscosity of pitch.
    • These chemical changes can lead to an increase in viscosity.
    • Thinness or viscosity, odour, ‘touch’, clarity, foaminess, and probably taste, were all considered.
    • The density and viscosity of wine that combine to create an impression of fullness or weight on the palate.
    • Once aspirated, due to their low viscosity and surface tension, they reach the dependent portion of the lung and cause a chemical pneumonia.
    • This wetting is a result of very low viscosity and surface tension high enough to be drawn into the cracks and pore structure of concrete by capillary action.
    • The texture and viscosity of the mixture is important, for it must be thick enough to adhere to the food, but not so thick that the coating becomes excessive and heavy.
    • In other words, if the material viscosity is close to water thin, the pump can cycle in the vicinity of 30 times per minute.
    • Acidification, texture, flavor and viscosity can be customized to meet the customer's needs.
    • In a rigid porous material, the normal component is clamped by viscosity and cannot move.
    • Electronics also compensate for changes in oil viscosity for consistent operation at all temperatures.
    • Hydrogels are usually clear or translucent in color and vary in viscosity or thickness.
    • Water so treated will show a change of temperature, surface tension, viscosity and electrical conductivity.
    • When the temperature of an emulsion is raised, there is a decrease in viscosity, which reduces emulsion stability.
    Synonyms
    thickness, density, firmness, solidity, cohesion, heaviness, degree of thickness, degree of density
    1. 1.1count noun A quantity expressing the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow.
      silicone oils can be obtained with different viscosities
      Example sentencesExamples
      • However, the temperature effect on the diffusion boundary layer involves the 1/6 power of the ratio of kinematic viscosities of water at the two temperatures.
      • The experiment uses fluids with known viscosities such as honey, corn syrup, glycerin and silicone oil.
      • We present a comparative study of the ultrafast photophysics of all-trans retinal in the protonated Schiff base form in solvents with different polarities and viscosities.
      • The problem involves materials of different densities, different viscosities, with very large variations in local Reynolds number (convection divided by viscous diffusion) and hydraulic conditions.
      • Whitaker used numerical methods to develop the interface between the two fluids with different viscosities in a Hele-Shaw cell.

Origin

Late Middle English: from Old French viscosite or medieval Latin viscositas, from late Latin viscosus (see viscous).
