viscosity    音标拼音: [vɪsk'ɑsəti]
n. 粘质,粘性

粘质,粘性

viscosity
粘性

viscosity
n 1: resistance of a liquid to shear forces (and hence to flow)
[synonym: {viscosity}, {viscousness}]

Viscosity \Vis*cos"i*ty\, n. [Cf. F. viscosit['e], LL.
viscositas.]
1. The quality or state of being viscous.
[1913 Webster]

2. (Physics) A property possessed by a viscous fluid, being a
resistance to the forces causing a fluid to flow, caused
by interactions between the molecules of the fluid and
between the fluid and the walls of the conduit through
which it moves; also, a measure of such a property.
[1913 Webster PJC]

  • Viscosity - Wikipedia
    [1] For liquids, it corresponds to the informal concept of thickness; for example, syrup has a higher viscosity than water [3] Viscosity is defined scientifically as a force multiplied by a time divided by an area Thus its SI units are newton-seconds per metre squared, or pascal-seconds [2]
  • 黏度_百度百科
    黏度(英文viscosity),是指流体对流动所表现的阻力。 当流体 (气体或液体) 流动时, 一部分在另一部分上面流动时, 就受到阻力, 这是流体的内摩擦力。 要使流体流动就需在流体流动方向上加一切线力以对抗阻力作用。

    Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another Viscosity denotes opposition to flow
