• 2003, Rodney O. Fox, Computational Models for Turbulent Reacting Flows:
However, it can be expected that 'scale-similarity' models of this form will be inadequate for describing non-equilibrium scalar fields resulting, for example, from non-equilibrium inlet flow conditions.
• 2015, Raymond L Bryant, The International Handbook of Political Ecology, page 504:
Scalar thickening is useful for understanding the propensity of scales to coalesce in certain times and places, or even how a particular scale provides conditions for other forms of scalar production.
4. (music) Of or pertaining to a musical scale.
5. (physics) Relating to particles with a spin () of 0 (known as spin 0).
